asp.net生成Excel并导出下载五种实现方法

有关Excel下载的文章网上想必有很多，利用闲暇时间整理了一些有Excel下载方法的文章，接下来介绍五种实现Excel下载的方法，感兴趣的朋友可以了解下，或许对你学习Excel下载有所帮助

方法一 通过GridView(简评：方法比较简单，但是只适合生成格式简单的Excel，且无法保留VBA代码),页面无刷新
aspx.cs部分

复制代码代码如下:

using System; 
using System.Collections; 
using System.Configuration; 
using System.Data; 
using System.Web; 
using System.Web.Security; 
using System.Web.UI; 
using System.Web.UI.HtmlControls; 
using System.Web.UI.WebControls; 
using System.Web.UI.WebControls.WebParts; 
using System.Text; 
public partial class DataPage_NationDataShow : System.Web.UI.Page 
{ 
private Data_Link link = new Data_Link(); 
private string sql; 
protected void Page_Load(object sender, EventArgs e) 
{ 
Ajax.Utility.RegisterTypeForAjax(typeof(DataPage_NationDataShow)); 
} 
protected void btnExcel_Click(object sender, EventArgs e) 
{ 
string strExcelName = "MyExcel"; 
strExcelName = strExcelName.Replace(@"/", ""); 
Data_Link link = new Data_Link(); 
string strSQL = this.hidParam.Value; 
DataSet ds = new DataSet(); 
ds = link.D_DataSet_Return(strSQL);//获得想要放入Excel的数据 
gvExcel.Visible = true; 
gvExcel.DataSource = null; 
gvExcel.DataMember = ds.Tables[0].TableName; 
gvExcel.DataSource = ds.Tables[0]; 
gvExcel.DataBind(); 
ExportToExcel(this.Page, gvExcel, strExcelName); 
} 
protected void gvExcel_RowDataBound(object sender, GridViewRowEventArgs e) 
{ } 
public override void VerifyRenderingInServerForm(Control control) 
{ } 
/// <summary> 
/// 工具方法，Excel出力(解决乱码问题) 
/// </summary> 
/// <param name="page">调用页面</param> 
/// <param name="excel">Excel数据</param> 
/// <param name="fileName">文件名</param> 
public void ExportToExcel(System.Web.UI.Page page, GridView excel, string fileName) 
{ 
try 
{ 
foreach (GridViewRow row in excel.Rows) 
{ 
for (int i = 0; i < row.Cells.Count; i++) 
{ 
excel.HeaderRow.Cells[i].BackColor = System.Drawing.Color.Yellow; 
} 
} 
excel.Font.Size = 10; 
excel.AlternatingRowStyle.BackColor = System.Drawing.Color.LightCyan; 
excel.RowStyle.Height = 25; 
page.Response.AppendHeader("Content-Disposition", "attachment;filename=" + fileName); 
page.Response.Charset = "utf-8"; 
page.Response.ContentType = "application/vnd.ms-excel"; 
page.Response.Write("<meta http-equiv=Content-Type content=text/html;charset=utf-8>"); 
excel.Page.EnableViewState = false; 
excel.Visible = true; 
excel.HeaderStyle.Reset(); 
excel.AlternatingRowStyle.Reset(); 
System.IO.StringWriter oStringWriter = new System.IO.StringWriter(); 
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
excel.RenderControl(oHtmlTextWriter); 
page.Response.Write(oStringWriter.ToString()); 
page.Response.End(); 
excel.DataSource = null; 
excel.Visible = false; 
} 
catch (Exception e) 
{ 
} 
} 
}

aspx部分
复制代码代码如下:

<head runat="server"> 
<script type="text/javascript"> 
//Excel DownLoad 
function excelExport(){ 
var hidText = document.getElementById("hidParam"); 
hidText.value = "some params"; 
document.getElementById("ExcelOutput").click(); 
} 
</script> 
</head> 
<body onload="pageInit()"> 
<form id="form1" runat="server"> 
<input type="button" value="EXCEL下载" style="width:100px;" onclick="excelExport()" id="excelBut" /> 
<input id="hidParam" type="text" runat="server" style="display:none;"/> 
<asp:Button runat="server" ID="ExcelOutput" style="display:none" Text= "EXCEL出力" Width="0px" onclick="btnExcel_Click" UseSubmitBehavior="false"/> 
<asp:GridView ID="gvExcel" runat="server" Height="95px" OnRowDataBound="gvExcel_RowDataBound" Visible="False"></asp:GridView> 
</form> 
</body>

在刚才的aspx.cs代码中
复制代码代码如下:

foreach (GridViewRow row in excel.Rows) 
{ 
for (int i = 0; i < row.Cells.Count; i++) 
{ 
excel.HeaderRow.Cells[i].BackColor = System.Drawing.Color.Yellow; 
} 
}

这部分是给表头添加样式。

有时候为了便于浏览，需要给交叉行添加样式，简单点的可以用下面这种：

复制代码代码如下:

excel.AlternatingRowStyle.BackColor = System.Drawing.Color.LightCyan;

但是细看一下会发现它把一整行的样式都改变了，包括后面那些没有用到的列。

解决办法是有，不过比较繁琐，就是修改每个单元格的样式。

复制代码代码如下:

int rowCount = excel.Rows.Count; 
int colCount = excel.HeaderRow.Cells.Count; 
for (int i = 0; i < rowCount; i++) 
{ 
for(int j=0;j<colCount; j++) 
{ 
excel.Rows[i].Cells[j].BackColor = System.Drawing.Color.LightCyan; 
} 
}

方法二 通过DataGrid(与方法一基本相同),页面无刷新

aspx.cs部分

复制代码代码如下:

public override void VerifyRenderingInServerForm(Control control) 
{} 
/// <summary> 
/// エクセル出力イベント 
/// </summary> 
/// <param name="sender"></param> 
/// <param name="e"></param> 
private void ExcelBut_Click(object sender, System.EventArgs e) 
{ 
DataGrid dgExcel = new DataGrid(); 
try 
{ 
DataSet ds = getExcelData(this.PageParams.Value);//出力データを取得する 
if(ds.Tables[0].Rows.Count>0) 
{ 
//エクセルへデータを投入する 
string execlName= "MyExcel"; 
Encoding encodingType=System.Text.Encoding.UTF8; 
dgExcel.DataMember=ds.Tables[0].TableName; 
dgExcel.DataSource=ds.Tables[0]; 
Response.Buffer = true; 
Response.Charset = "utf-8"; 
Response.AppendHeader("Content-Disposition", "attachment;filename=" + execlName+ ".xls"); 
Response.ContentEncoding = encodingType; 
Response.ContentType = "application/ms-excel"; 
StringWriter oStringWriter = new StringWriter(); 
HtmlTextWriter oHtmlTextWriter = new HtmlTextWriter(oStringWriter); 
dgExcel.DataBind(); 
dgExcel.Visible = true; 
dgExcel.RenderControl(oHtmlTextWriter); 
Response.Write(oStringWriter.ToString()); 
Response.Flush(); 
Response.Close(); 
dgExcel.DataSource = null; 
dgExcel.Visible = false; 
} 
else 
{ 
Response.Write("<script>alert('xxxxxx')</script>"); 
} 
} 
catch(Exception ex) 
{ 
Response.Write("<script>alert('oooooo')</script>"); 
} 
}

aspx部分
复制代码代码如下:

<head runat="server"> 
<script type="text/javascript"> 
//Excel DownLoad 
function excelExport(){ 
var hidText = document.getElementById("hidParam"); 
hidText.value = "some params"; 
document.getElementById("ExcelOutput").click(); 
} 
</script> 
</head> 
<body onload="pageInit()"> 
<form id="form1" runat="server"> 
<input type="button" value="EXCEL下载" style="width:100px;" onclick="excelExport()" id="excelBut" NAME="excelBut"/> 
<input id="hidParam" type="text" runat="server" style="display:none;" NAME="hidParam"/> 
<asp:Button runat="server" ID="ExcelOutput" style="display:none" Text= "EXCEL出力" Width="0px" onclick="btnExcel_Click" UseSubmitBehavior="false"/> 
<asp:datagrid id="gvExcel" Visible="False" Runat="server" style="Z-INDEX: 107; POSITION: absolute; TOP: 72px; LEFT: 520px" 
Width="80px" Height="40px"></asp:datagrid> 
</form> 
</body>

方法三 以XML形式的Excel方式(可以设置丰富的样式，并可以有多个sheet，但需要模版。速度很快，但生成的文件较大，且无法保留VBA代码)

具体方法：把模版以 XML Document形式另存为A.xml。然后参照A.xml中的内容即可

复制代码代码如下:
 
private void ExcelBut_Click(object sender, System.EventArgs e) 
{ 
DataSet ds = new DataSet(); 
string ExcelFileName = ""; 
DataRow dr=[------列名信息-------]; 
try 
{ 
ExcelFileName = Path.Combine(Request.PhysicalApplicationPath + "/ExcelFile", "MyExcel.xls"); 
//获取Excel需要的数据 
ds = [------获得数据-------]; 
if (ds.Tables.Count == 0) 
{ 
Response.Write("<script type='text/javascript'>alert('无数据');</script>"); 
return; 
} 
int sheetNum = ds.Tables.Count / 2; 
StreamWriter writer = new StreamWriter(ExcelFileName, false); 
//Styles标签前面的信息相当于'头信息'，不需要改变 
writer.WriteLine("<?xml version=\"1.0\"?>"); 
writer.WriteLine("<?mso-application progid=\"Excel.Sheet\"?>"); 
writer.WriteLine("<Workbook xmlns=\"urn:schemas-microsoft-com:office:spreadsheet\""); 
writer.WriteLine("xmlns:o=\"urn:schemas-microsoft-com:office:office\""); 
writer.WriteLine("xmlns:x=\"urn:schemas-microsoft-com:office:excel\""); 
writer.WriteLine("xmlns:ss=\"urn:schemas-microsoft-com:office:spreadsheet\""); 
writer.WriteLine("xmlns:html=\"http://www.w3.org/TR/REC-html40\">"); 
writer.WriteLine("<DocumentProperties xmlns=\"urn:schemas-microsoft-com:office:office\">"); 
writer.WriteLine("<LastAuthor>Automated Report Generator Example</LastAuthor>"); 
writer.WriteLine(string.Format("<Created>{0}T{1}Z</Created>", DateTime.Now.ToString("yyyy-mm-dd"), DateTime.Now.ToString("HH:MM:SS"))); 
writer.WriteLine(" <Company>51aspx.com</Company>"); 
writer.WriteLine(" <Version>11.6408</Version>"); 
writer.WriteLine("</DocumentProperties>"); 
writer.WriteLine("<ExcelWorkbook xmlns=\"urn:schemas-microsoft-com:office:excel\">"); 
writer.WriteLine("<WindowHeight>6195</WindowHeight>"); 
writer.WriteLine(" <WindowWidth>18495</WindowWidth>"); 
writer.WriteLine(" <WindowTopX>525</WindowTopX>"); 
writer.WriteLine(" <WindowTopY>4260</WindowTopY>"); 
writer.WriteLine(" <AcceptLabelsInFormulas/>"); 
writer.WriteLine(" <ProtectStructure>True</ProtectStructure>"); 
writer.WriteLine(" <ProtectWindows>False</ProtectWindows>"); 
writer.WriteLine("</ExcelWorkbook>");
