asp.net服务端使用正则表达式验证数据合法性．

            ValidTextBox VT =  new ValidTextBox();
            VT.IsValidField(tb1,5,"闭填", false);
            VT.IsValidDate(tb2,10,"日期", false);
            VT.IsValidNumber(tb3,5,"数字", false);
            VT.IsValidSSN(tb4,18,"身份证", false);
            VT.IsValidUrl(tb5,30,"URL", false);
            VT.IsValidZip(tb6,10,"ZIP", false);


             if (!VT.IsValid)

             {
                ／／string js = "<script>alert('"+VT.ErrorMsg+"');</script>";
                ／／Response.Write(js);
                Label1.Text = VT.ErrorMsg;
            }
