c#字符串截取函数

//region 字符串截取函数//首先引入System.Text命名空间    public static string CutString(string inputString,int len)     {         ASCIIEncoding ascii = new ASCIIEncoding();         int tempLen=0;         string tempString="";         byte[] s = ascii.GetBytes(inputString);         for(int i=0;i<s.Length;i++)         {             if((int)s[i]==63) //63:表示问号：?            {                 tempLen+=2;             }             else             {                 tempLen+=1;             }
