判断字符串中是否有中文

方法一：

//判断字符串中是否有中文，true有，false没有。public bool IsChina(string CString)        {            bool BoolValue = false;            for (int i = 0; i < CString.Length; i++)            {                if (Convert.ToInt32(Convert.ToChar(CString.Substring(i, 1))) > Convert.ToInt32(Convert.ToChar(128)))                {                    BoolValue = true;                }                           }            return BoolValue;        }

方法二：

public bool WordsIScn(string words){string TmmP;for (int i = 0; i < words.Length; i++){TmmP = words.Substring(i, 1);byte[] sarr = System.Text.Encoding.GetEncoding("gb2312").GetBytes(TmmP);if (sarr.Length == 2){return true;}}return false;}
