Check for specific value in a combobox

How can I check that a combobox in winforms contains some value?

Is there any way of doing it without iterating through all items?

Using the accepted answer did not work for me as it always returned false even though a check of the list show the value present. What I use is the FindStringExact method, as recommend by Louis and Amit. In this case its a value entered in the comboBox text box.

var index = comboBox1.FindStringExact(comboBox1.Text)
if(index > -1)
{
    //Success followup code
}

To find exact data from combo box we have to check with FindStringExact

int resultIndex = cbEmployee1.FindStringExact(item.Text);

The other answers didn't work for me.

This did:

if (comboBox1.Items.Cast<string>().Any(i => i == position))
{
    // Items contains value
}

Hope this helps!

int index = comboBox1.FindString("some value"); comboBox1.SelectedIndex = index;

There's also FindStringExact http://msdn.microsoft.com/en-us/library/c440x2eb.aspx

if (comboBox1.Items.Contains("some value"))
{

}

If the items are some custom object instead of strings you might need to override the Equals method.
