上传文件(code)

利用上传文件控件,做的点练习

        //上传到服务器的路径 (以后可以在这里改)
        string savePath = Server.MapPath("");
        //获取file控件取得的路径
        string Path = File.Value;
        string[] SplitPath = Path.Split('\\');

        string lastPath = SplitPath[SplitPath.Length - 1];

        string[] fileName = lastPath.Split('.');
        string lastfile = fileName[fileName.Length - 1];

        try
        {
            if (lastfile == "jpg")
            {
                savePath = savePath + "\\" + lastPath;
                //上传文件到服务器 SaveAs
                File.PostedFile.SaveAs(savePath);
                labmessage.Text = "Uploaded";
            }
            else
            {
                labmessage.Text = "The file is not rigth";
            }

        }
        catch(Exception ex)
        {
            labmessage.Text = ex.Message;
        }
