window 服务安装卸载

在VS2008命令控制台下,执行installitil.exe

1. 注册Windows服务

C:"WINDOWS"Microsoft.NET"Framework"v2.0.50727>installutil @fileName

2. 卸载Windows服务

C:"WINDOWS"Microsoft.NET"Framework"v2.0.50727>installutil /u @fileName

@fileName是Winfows服务文件路径和文件名如:c:\MyService.exe



或者在VS2008命令行提示行下直接输入installutil.exe命令

C# 使用正则表达式去掉字符串中的数字,或者去掉字符串中

01 /// <summary>  

02         /// 去掉字符串中的数字  

03         /// </summary>  

04         /// <param name="key"></param>  

05         /// <returns></returns>  

06         public static string RemoveNumber(string key)  

07         {

09         }        /// <summary>  

10         /// 去掉字符串中的非数字  

11         /// </summary>

14         public static string RemoveNotNumber(string key)  

15         {

 效果:输入"High:4"
第一个函数,输出结果是"High:"
第二个函数,输出结果是"4"
