一、去除首尾字符串

复制代码 代码如下:

///<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);

}
