我硬编码了文件路径。你可以从文本框中获取它并分配给filePath变量。



这是Link Button Click事件。您必须使用System.IO和System .NET作为额外的库，这是用于Path.getExtention（）和WebClient类。

Please See this solution. I have tested now with sample.Please Mark as answered if you got help from this.

I hardcoded the file path. You can get it from text box and assign to filePath variable.

This is Link Button Click event. You have to use System.IO and System .NET as extra libraries, which is for Path.getExtention() and WebClient Class.

using System.IO;
using System.Net;

protected void LinkButton1_Click(object sender, EventArgs e)
      {
          string filePath = "C:\\GIHAN\\Employee Profile - Senior Engineer Technology.docx";
          string fileExtention = Path.GetExtension(filePath);
          WebClient client = new WebClient();
          Byte[] buffer = client.DownloadData(filePath);
          Response.ContentType = ReturnExtension(fileExtention);

          Response.AddHeader("content-length", buffer.Length.ToString());
          Response.BinaryWrite(buffer);
      }

这是退货延期功能

Here is the Return Extension Function

private string ReturnExtension(string fileExtension)
        {
            switch (fileExtension)
            {
                case ".htm":
                case ".html":
                case ".log":
                    return "text/HTML";
                case ".txt":
                    return "text/plain";

                case ".bmp":
                    return "image/bmp";
                case ".wav":

                case ".rtf":

                case ".asp":

                default:
                    return "application/octet-stream";
            }
