Question

当用户点击“确定”按钮时，我会将其输入验证为：

private void btnOk_Click(object sender, EventArgs e)
{
    myTxtField_Validated(this, e);
    myTxtField2_Validated(this, e);

    CustomObject obj = new CustomObject .....
}

在验证内部，我使用错误提供程序通知用户字段中的输入必须符合某些条件。

如果验证中断，我如何以静默方式中断此部分CustomObject obj = new CustomObject ....的执行。它可以按预期使用现有的验证代码。

使用私有布尔成员可以轻松实现这一点，并按照以下方式实现：

private bool _validatedTextFields;
private void btnOk_Click(object sender, EventArgs e)
{
   myTxtField_Validated(this, e);
   myTxtField2_Validated(this, e);

   if (_validatedTextFields)
   {
   CustomObject obj = new CustomObject .....
   }
}

private void myTxtField_Validated(object sender, EventArgs e)
{
  //your validation...
  _validatedTextFields = true //only set your member to true if it has been validated.
}

private void myTxtField2_Validated(object sender, EventArgs e)
{
  //your validation...
  _validatedTextFields = true //only set your member to true if it has been validated.
}

验证规则中断时，停止执行并关注表单
