.NET截取指定长度汉字超出部分以“…”代替

 

public static string StringTruncat(string oldStr, int maxLength, string endWith)

    {
        if (string.IsNullOrEmpty(oldStr))
            return oldStr + endWith;
        if (maxLength < 1)
            throw new Exception("返回的字符串长度必须大于[0]");
        if (oldStr.Length > maxLength)
        {
            string strTmp = oldStr.Substring(0,maxLength);
            if (string.IsNullOrEmpty(endWith))
                return strTmp;
            else
                return strTmp + endWith;
        }
        return oldStr;
}
