public static string GetSubString(string str, int length)
        {
            string temp = str;
            int j = 0;
            int k = 0;
            for (int i = 0; i < temp.Length; i++)
            {
                if (Regex.IsMatch(temp.Substring(i, 1), @"[\u4e00-\u9fa5]+"))
                {
                    j += 2;
                }
                else
                {
                    j += 1;
                }
                if (j <= length)
                {
                    k += 1;
                }
                if (j >= length)
                {
                    temp = temp.Substring(0, k);
                    break;
                }
            }
            
            return temp;
    }
<asp:LinkButton ID="News_Name" runat="server" Text='<%#GetSubString(Eval("P_Name"),2)%>'></asp:LinkButton>CS1502: 与“admin_admin_News.GetSubString(string, int)”最匹配的重载方法具有一些无效参数
