推荐答案

尝试:

if (myListBox.Items.Contains(myTextBox.Text))
    {
    Console.WriteLine("YES");
    }

尝试

foreach(ListItem item in yourlstbox.Items)
{
if(item.Text == yourtxtName.Text)
{
// isExists = true;  your condition 
break;
}
}

或更好地在TextBox的TextChangedEvent代码上编写代码，例如:-

or better to write code on TextBox''s TextChangedEvent code like :-

private void textBox1_TextChanged(object sender, EventArgs e)
{
int index = listBox1.FindString(this.textBox1.Text);
if (0 <= index)
{
listBox1.SelectedIndex = index;
}
}
