本文實(shí)例講述了ASP.NET實(shí)現(xiàn)推送文件到瀏覽器的方法。。具體分析如下：

這里主要實(shí)現(xiàn)從服務(wù)器到瀏覽器，推送文件，提供用戶下載/瀏覽的功能。

提示： 在AJAX UpdatePanel里面將無效。如果代碼從按鈕單擊事件中被調(diào)用，該按鈕需要在 AJAX UpdatePanel的外部。

具體代碼如下：

/// <summary>/// Downloads (pushes) file to the client browser. /// **** NOTE **** Cannot be done from inside an AJAX UpdatePanel control./// </summary>/// <param name="fullFilePath">The full file path of the file</param>protected void DownloadFile(string fullFilePath){  // Gets the File Name  string fileName = fullFilePath.Substring(fullFilePath.LastIndexOf('//') + 1);  byte[] buffer;  using (FileStream fileStream = new FileStream(fullFilePath, FileMode.Open))  {    int fileSize = (int)fileStream.Length;    buffer = new byte[fileSize];    // Read file into buffer    fileStream.Read(buffer, 0, (int)fileSize);  }  Response.Clear();  Response.Buffer = true;  Response.BufferOutput = true;  Response.ContentType = "application/x-download";  Response.AddHeader("Content-Disposition", "attachment; filename=" + fileName);  Response.CacheControl = "public";  // writes buffer to OutputStream  Response.OutputStream.Write(buffer, 0, buffer.Length);  Response.End();}

希望本文所述對大家的asp.net程序設(shè)計有所幫助。
