以 regular expression 驗證 Email 格式

筆記用...

檢查字串

/^.+@.+\..+$/

C#

public bool CheckEmailFormat(string email)
{
    //c#裡要把前後的斜線拿掉
    string emailFormat = @"^.+@.+\..+$";
    System.Text.Reqex reg = new System.Text.Regex(emailFormat);
    return reg.IsMatch(email);
}

Javascript

function IsEmail(value) {
    var objRegExp = /^.+@.+\..+$/;

    if (!objRegExp.test(value))
        return false;
    return true;
}
