说明:刚刚写了一篇《IHttpHandler的妙用(2):防盗链!我的资源只有我的用户才能下载》的文章,网址:http://blog.csdn.net/zhoufoxcn/archive/2008/01/11/2036995.aspx。估计很多朋友对不同后缀的文件对应的MIME类型不熟悉(实际上这么多我也记不住),所以将平常常见的一些文件后缀对应的MIME类型写了一个对照表,现在奉献给大家:

文件后缀

二进制数据文件
*.bin
application/x-macbinary
 
*.csv
text/comma-separated-values
 
*.css
text/css

Word类型文件
*.gz
application/gzip
GNU 压缩格式文件
*.gif
p_w_picpath/gif
 
*.hlp *.chm
application/mshelp
 
*.htm *.html *.shtml
text/html
 
*.js

*.jpeg *.jpg *.jpe
p_w_picpath/jpeg
 
*.mpeg *.mpg *.mpe

application/msaccess
 
*.ppt *.ppz *.pps *.pot
application/mspowerpoint
 
*.pdf

*.rm
*.rmvb
application/vnd.rn-realmedia
 
*.swf *.cab
application/x-shockwave-flash
 
*.txt
text/plain
 
*.xls *.xla
application/msexcel
 
*.z
application/x-compress
 
*.zip
application/x-zip-compressed
 
 注:以上列出了较为常用的文件格式与MIME的对照关系,如果在实际开发中遇到生僻的文件格式,其实也不用惊慌,利用asp.net的上传组件FileUpload组件轻松搞定,向Web窗体中拖一个FileUpload组件,然后添加一个Button,Button的Click事件代码如下:
protected void btnUpload_Click(object sender, EventArgs e)
    {
        
if (FileUpload1.HasFile)
        {
            Response.Write(
"MIME=" + FileUpload1.PostedFile.ContentType);
        }
    }
这样就能得到该类型文件的MIME类型了。
