创建一个指向您文件的超链接。

Create a hyperlink to your file.

我不知道如何使用linkbutton下载文件。

and i dont know how to download the file using the linkbutton.

LinkBut​​ton 就像一个普通的按钮， CSS 就像一个锚标签。

试试这个

LinkButton is like a normal button with CSS like an anchor Tag.
try this

protected void LinkButton1_Click(object sender, EventArgs e)
       {
           string filePath = "Your file path from the folder";
           Response.ContentType = ContentType;
           Response.AppendHeader("Content-Disposition", "attachment; filename=" + System.IO.Path.GetFileName(filePath));
           Response.WriteFile(filePath);
           Response.End();
       }
