在LinkBut​​ton Onclick内尝试类似下面的内容

Try something like below inside LinkButton Onclick

string filePath = "ReplacethePathHereWithYours";
   Response.ContentType = "ContentType"//Modify ContentType accordingly like pdf etc;
   Response.AppendHeader("Content-Disposition", "attachment; filename=" + Path.GetFileName(filePath));
   Response.WriteFile(filePath);
   Response.End();
