无法在标签中放置错误消息

我希望我的错误消息显示在我的标签中(lblNewTemperature)但是,每次我使用格式lblNewTemperature.Text = "Error message"时,它都无法正常工作,并且与我混淆整体代码。知道为什么会这样吗?

if (!double.TryParse(txtTemperature.Text, out inputTemperature))  // Checking that user input is valid
        {
            MessageBox.Show("ERROR: Please enter a numeric temperature to convert.");  // Error message that is displayed
            txtTemperature.ResetText();  // Resets the form
            txtTemperature.Focus();  // Places the user's cursor back in the Temperature textbox
        }
