windows Media player 等avi,wmv,asf,mov,rm,ra,ram的Web播放-优快云博客

本文介绍了一段用于判断视频文件格式并根据不同格式输出相应播放代码的C#程序。该程序首先从URL中提取文件扩展名，然后根据扩展名确定视频类型，并针对不同类型的视频文件（如AVI、WMV、RM等）输出特定的HTML代码以实现网页内嵌播放。

string Exts = string.Empty;
string isExt = string.Empty;

        if (strUrl != "")
        {
            isExt = strUrl.Substring(strUrl.LastIndexOf('.') + 1).ToLower();
        }
        else
        {
            isExt = "";
        }

        Exts = "avi,wmv,asf,mov,rm,ra,ram";
        if (Exts.IndexOf("isExt") >= -1)
        {
            switch (isExt)
