	///<summary>

	 /// 截前后字符(串)

	 ///</summary>

	 ///<param name="val">原字符串</param>

	 ///<param name="str">要截掉的字符串</param>

	 ///<param name="all">是否贪婪</param>

	 ///<returns></returns>

	        private string GetString(string val,string str,bool all)

	        {

	            return Regex.Replace(val, @"(^(" + str + ")" + (all ? "*" : "") + "|(" + str + ")"+(all ? "*" : "") + "$)", "");

	        }

	 

	二、去除首尾字符

	 

	复制代码 代码如下:

	

	        /// <summary>

	        ///

	        /// </summary>

	        /// <param name="val">原字符串</param>

	        /// <param name="c">要截取的字符</param>

	        /// <returns></returns>

	        private string GetString(string val,char c)

	        {

	            return val.TrimStart(c).TrimEnd(c);

	        }
