ASP.NET中上传并读取Excel文件数据示例

<INPUT id="File1" type="file" name="File1" runat="server"> 
<asp:Button id="Button1" runat="server" Text="Button"></asp:Button> 
<asp:DataGrid id="DataGrid1" runat="server"></asp:DataGrid> 
 
在代码视图中首先导入OleDb命名空间： 
using System.Data.OleDb; 

在按钮的单击事件中输入如下代码： 
 代码如下:

string strPath="c://test//" + DateTime.Now.ToString("yyyyMMddhhmmss") + ".xls"; 

File1.PostedFile.SaveAs(strPath); 

string mystring="Provider = Microsoft.Jet.OLEDB.4.0 ; Data Source = '"+ strPath +"';Extended Properties=Excel 8.0"; 

OleDbConnection cnnxls = new OleDbConnection (mystring); 

OleDbDataAdapter myDa =new OleDbDataAdapter("select * from [Sheet1$]",cnnxls); 

DataSet myDs =new DataSet(); 

myDa.Fill(myDs); 

DataGrid1.DataSource=myDs.Tables[0]; 

DataGrid1.DataBind(); 
 
其中C:/test对ASPNET用户要有读写的权限.
