如何在验证码控制中检查条件? [英] how to check the condition in captcha control?

问题描述

您好，先生，
我在ASP.NET中使用验证码控件.在设计页面上，我有文本框，按钮和验证码控件.现在我想要当我在文本框中输入与验证码相同的文本并单击按钮时，请检查输入的文本是否匹配.
所以我想验证一下输入的文本是否与验证码匹配.
如果不匹配，则给出错误消息.

谢谢.

检查条件.

check condition like that.

protected void Button1_Click(object sender, EventArgs e)
    {
        CaptchaControl1.ValidateCaptcha(TextBox1.Text);
        if (!CaptchaControl1.UserValidated)
        {
            Label1.Text = " not sucessfull";
            return;
        }
        else
        {
            Label1.Text = "Sucessfull";
        }
}

If you are still stuck, post the code, work you did and where you are unable to get it. All you need is to compare and then raise the flag based on the comparison result.
