 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。
