问题描述

嗨...
我正在使用验证码控制，我需要验证该代码.
我给出了这样的代码，

Hi...
Im using captcha control and i need to validate that code.
I gave code like this,

protected void btnNext_Click(object sender, EventArgs e)
        {
            ccJoin.ValidateCaptcha(txtCaptcha.Text);
            if (!ccJoin.UserValidated)
            {
                lblMsg.Text = "Incorrect code";
                return;
            }
            else
            {
                lblMsg.Text = "Code matched";

            }
        }

但是即使在文本框中输入正确的代码后，我也只会收到不正确的消息...指导我
