如何在Winforms中使用数据注释验证器？

public class User
{
    [Required]
    public string Name { get; set; }

    [Range(18, 100)]
    public int Age { get; set; }

    [EmailAddress]
    public string Email { get; set; }
}

private void nameTextBox_Validating(object sender, CancelEventArgs e)
{
    var user = (User)bindingSource.Current;
    var validationContext = new ValidationContext(user);
    validationContext.MemberName = nameof(User.Name);
    var validationResults = new List<ValidationResult>();

    if (!Validator.TryValidateProperty(user.Name, validationContext, validationResults))
    {
        errorProvider.SetError(nameTextBox, validationResults.First().ErrorMessage);
        e.Cancel = true;
    }
    else
    {
        errorProvider.SetError(nameTextBox, null);
    }
}

private void saveButton_Click(object sender, EventArgs e)
{
    var user = (User)bindingSource.Current;
    var validationContext = new ValidationContext(user);
    var validationResults = new List<ValidationResult>();

    if (!Validator.TryValidateObject(user, validationContext, validationResults, true))
    {
        foreach (var validationResult in validationResults)
        {
            var control = GetControlByPropertyName(validationResult.MemberNames.First());
            errorProvider.SetError(control, validationResult.ErrorMessage);
        }
    }
    else
    {
        // 保存数据的逻辑
    }
}
