检查是否在文本框中输入电子邮件 [英] Check if input in textbox is email

问题描述

我试图验证是否userinput是（添加成员数据库）的的电子邮件地址。

I am trying to validate if the userinput is an email adress (adding a member to database).

用户将进入文本框的数据，当验证事件被调用;我要检查，如果输入的是一个有效的电子邮件地址。因此，由ATLEAST的@和点（。）的字符串。

The user will enter data in TextBox, when the validating event gets called; I want to check if the input is a valid email adress. So consisting of atleast an @ and a dot(.) in the string.

有没有办法通过代码来做到这一点，或者从MaskedTextBox中口罩？

Is there any way to do this through code, or perhaps with a Mask from the MaskedTextbox?

推荐答案

不要用正则表达式打扰。 这是一个坏主意。

Don't bother with Regex. It's a Bad Idea.

我通常从不的使用异常来控制程序流程，但就个人而言，在这种情况下，我宁愿让谁创造了 MailAddress 类做的工作对我来说：

I normally never use exceptions to control flow in the program, but personally, in this instance, I prefer to let the experts who created the MailAddress class do the work for me:

try
{
    var test = new MailAddress("");
}
catch (FormatException ex)
{
    // wrong format for email
}
