如何验证已启用的空文本框而不考虑已禁用的文本框

问题描述

我应该如何声明仅验证已启用的文本框?"

How should I declare "validate only Text Boxes which are enabled?"

 public static bool IsEmpty(Form myform)
        {
            foreach (Control myControl in myform.Controls)
            {
if ((myControl.GetType() == typeof(TextBox)) || (myControl.GetType() == typeof(ComboBox)))
                {
                    myControl.Text = myControl.Text.Trim();
                    if (myControl.Text == "")
                    {
                        MessageBox.Show(myControl.Name.Substring(3).ToString() + " is empty.");
                        myControl.Focus();
                        return true;
                    }
                    myControl.Text = TrimBetween(myControl.Text);
                }

推荐答案

if ((myControl.GetType() == typeof(TextBox)) || (myControl.GetType() == typeof(ComboBox)))
    {
    //myControl.Text = myControl.Text.Trim();
    if (myControl.Enabled && string.IsNullOrWhiteSpace(myControl.Text))
        {
        MessageBox.Show(myControl.Name.Substring(3).ToString() + " is ");
        myControl.Focus();
        return true;
        }
    myControl.Text = TrimBetween(myControl.Text);
    }

BTW:我已经删除了Trim，并更改了检查-如果您使用IsNullOrWhiteSpace方法，它将为您完成此操作.

BTW: I have removed the Trim, and changed the check - if you use the IsNullOrWhiteSpace method it does that for you.
