如何在ASP.NET中的gridview中添加超链接 [ ^ ]

如果要正常打开文件，可以使用响应.Redirect（YourFilePath）。如果您想下载该文件，那么您可以使用下面的功能。在GridView的RowCommand事件中调用该函数并传递相应文件的路径。试试这个：

 <！ -    这应该存在于gridview itemtemplate内的aspx文件中   - >   
 < span class =code-keyword><   asp：LinkBut​​ton     ID   =  lnkView    runat   =  server    文字  = < span class =code-keyword>查看文档    CommandName   = 查看    CommandArgument   ='  <％ #EVal（  URL） ％>'  /  >  

  protected   void  Gridview_RowCommand（ Object  sender，GridViewCommandEventArgs e）
 {
  if （e.CommandName ==  查看）
 {
 DownloadFile（e.CommandArgument.ToString（））; 
} 
} 
 
  public   void  DownloadFile（  string  FilePath）
 {
 Response.Clear（）; 
 Response.ContentType =  @  application\octet-stream; 
 System.IO.FileInfo file =  new  System.IO.FileInfo（Server.MapPath（FilePath））; 
 Response.AddHeader（  Content-Disposition，  attachment; filename = + file.Name）; 
 Response.AddHeader（  Content-Length，file.Length.ToString（）） ; 
 Response.ContentType =   application / octet-stream; 
 Response.WriteFile（file.FullName）; 
 Response.Flush（）; 
} 

希望它有所帮助！

how to add Hyperlink in gridview in ASP.NET[^]

If you want to open the file normally then you can use Response.Redirect(YourFilePath). And if you want to download the file then you can use the function below. Call the function in your RowCommand Event of GridView and pass the path of corresponding file. Try this:

<!--This should be there in your aspx file inside gridview itemtemplate-->
<asp:LinkButton ID="lnkView" runat="server" Text="View Document" CommandName="View" CommandArgument='<%#EVal("URL")%>'/>

protected void Gridview_RowCommand(Object sender, GridViewCommandEventArgs e)
{
   if(e.CommandName == "View")
   {
       DownloadFile(e.CommandArgument.ToString());
   }
}

public void DownloadFile(string FilePath)
{
    Response.Clear();
    Response.ContentType = @"application\octet-stream";
    System.IO.FileInfo file = new System.IO.FileInfo(Server.MapPath(FilePath));
    Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
    Response.AddHeader("Content-Length", file.Length.ToString());
    Response.ContentType = "application/octet-stream";
    Response.WriteFile(file.FullName);
    Response.Flush();
}

Hope it helps!
