Serializer 

启动项目

WPFApplication

获取正在运行程序的完整路径

 //结果 "D:\用户目录\我的文档\Visual Studio 2013\Projects\Serializer\WPFApplication\bin\Debug\WPFApplication.exe"
            string a = System.Reflection.Assembly.GetEntryAssembly().Location;

            //结果 '\'
            char c = System.IO.Path.DirectorySeparatorChar;
            //结果  76
            int b =System.Reflection.Assembly.GetEntryAssembly().Location.LastIndexOf(System.IO.Path.DirectorySeparatorChar);

获取运行程序所在文件夹的路径
            //结果   "D:\用户目录\我的文档\Visual Studio 2013\Projects\Serializer\WPFApplication\bin\Debug"
            string appDir = System.IO.Path.Combine(System.Reflection.Assembly.GetEntryAssembly().Location.Substring(0, System.Reflection.Assembly.GetEntryAssembly().Location.LastIndexOf(System.IO.Path.DirectorySeparatorChar)));

拼接文件夹
            //结果  "D:\用户目录\我的文档\Visual Studio 2013\Projects\Serializer\WPFApplication\bin\Update"
            string updateFileDir = System.IO.Path.Combine(System.IO.Path.Combine(appDir.Substring(0, appDir.LastIndexOf(System.IO.Path.DirectorySeparatorChar))), "Update");

获得运行程序的名字 去掉exe
            //结果  "WPFApplication"
          string  _callExeName = System.Reflection.Assembly.GetEntryAssembly().Location.Substring(System.Reflection.Assembly.GetEntryAssembly().Location.LastIndexOf(System.IO.Path.DirectorySeparatorChar) + 1).Replace(".exe", "");

        }
