IWebSiteLib.Tools.InterceptCharacter为截取字符串的方法

public static string InterceptCharacter(string Character, int extent)
        {
            string TempString = "";
            if (System.Text.Encoding.Default.GetByteCount(Character) > extent)
            {
                int iCount = Character.Length;
                while (true)
                {
                    iCount--;
                    TempString = Character.Substring(0, iCount);
                    if (System.Text.Encoding.Default.GetByteCount(TempString) <= extent)
                    {
                        break;
                    }
                }
                return TempString + "";
            }
