Solution 2

Try:

C#

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

Did I say to use FindStringExact? No, I didn't think I did...

but you wrote console.writeline .. i actually wnt to compare the text what i have entered in the textbox with listbox items.. when i click on button if the data matches it should proceed to next form

So replace the Console code with the code to open your form?
Are you a programmer and capable of thinking for yourself or only capable of following instructions? Because if it is the latter, then you need to change courses...

OriginalGriff is right!!! @zahra1991-are you a programmer? or you dont know how to show next Form

Solution 1

Try

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

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

C#

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