Mime类型与文件后缀对照表及探测文件MIME的方法

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

*.txt

text/plain

 

*.xls *.xla

application/msexcel

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。
