上传大文件

首先在web.config中添加：

<system.web>

<httpRuntime maxRequestLength="40960" executionTimeout="6000"/>

</system.web>

提交按钮的代码如下

protected void btnfileup_Click(object sender, EventArgs e)
   {
       try
       {
           FileUpload1.PostedFile.SaveAs(Server.MapPath("file/"+FileUpload1.FileName));
           Page.ClientScript.RegisterStartupScript(Page.GetType(), "message", "<script language='javascript' defer>alert('上传成功！');</script>");
         
       }
       catch (Exception ex)
       {

           Response.Write(ex.Message.ToString());
           Page.ClientScript.RegisterStartupScript(Page.GetType(), "message", "<script language='javascript' defer>alert('上传失败！');</script>");

        
       }
   }
