推荐答案

您好，



您可以使用正则表达式：

使用正则表达式电子邮件地址验证 [ ^ ]

而不是RegEx来验证电子邮件地址，你也可以试试这个：

只需检查给定的电子邮件地址包含@和.com不足以验证电子邮件地址：如果您只是检查@和.com，那么甚至 .com @ 有效。

Hi,

You can use a regular expression:

Instead of a RegEx to validate an email address, you can also try this:

Just checking whether the given email address contains "@" and ".com" wouldn't be enough to validate an email address: if you just would check for "@" and ".com", then even .com@ would be valid.

你真的不需要一个蒙面文本框。您应该将此代码放在要验证电子邮件的位置。

You don't really need a masked text box. You should just put this code where you want to validate the email.

if (TextBox1.Text.Contains("@")) {
    if (TextBox1.Text.Contains(".com")) {
        MessageBox.Show("Valid Email");
    }
} else {

}
