ASP.NET 中 ContentType 类型

代码如:
<% response.ContentType ="text/html" %> 
<!--＃i nclude virtual="/ContentType.html" -->
显示的为网页,而
<% response.ContentType ="text/plain" %> 
<!--＃i nclude virtual="/sscript/ContentType.html" -->
则会显示html原代码.

以下为一些常用的 ContentType
GIF images 
<% response.ContentType ="image/gif" %> 
<!--＃i nclude virtual="/myimage.gif" -->
JPEG images 
<% response.ContentType ="image/jpeg" %> 
<!--＃i nclude virtual="/myimage.jpeg" --> 
TIFF images 
<% response.ContentType ="image/tiff" %> 
<!--＃i nclude virtual="/myimage.tiff" --> 
MICROSOFT WORD document 
<% response.ContentType ="application/msword" %> 
<!--＃i nclude virtual="/myfile.doc" -->
RTF document 
<% response.ContentType ="application/rtf" %> 
<!--＃i nclude virtual="/myfile.rtf" -->
MICROSOFT EXCEL document 
<% response.ContentType ="application/x-excel" %> 
<!--＃i nclude virtual="/myfile.xls" -->
MICROSOFT POWERPOINT document 
<% response.ContentType ="application/ms-powerpoint" %> 
<!--＃i nclude virtual="/myfile.pff" -->
PDF document 
<% response.ContentType ="application/pdf" %> 
<!--＃i nclude virtual="/myfile.pdf" -->
ZIP document 
<% response.ContentType ="application/zip" %> 
<!--＃i nclude virtual="/myfile.zip" -->

RAR document

Response.ContentType = "application/x-msdownload ; Charset=utf-8";   
Response.AddHeader("Content-Disposition", "attachment; filename=...");

前边为类型， 后边为相应Type,只需要TYPE就可以.例如：‘ez‘ => ‘application/andrew-inset‘, 

输出页面（尚未验证）

private void Page_Load(object sender, System.EventArgs e)
{
   try
      {
         string id = Request.QueryString["id"];

         int ID = Int32.Parse(id);

         byte[] imagebyte = //Get image data by image’s ID             

         Response.ContentType = "image/gif"; 

         Response.BinaryWrite( imagebyte );
       }

  catch(Exception Error)
       {
           Response.Write(Error.Message);

       }   
}
