Question

Hi I want to use my code below for a thread. I have some example code for invoke but I dont know how to do it when it comes to my combo box selected item going to string.

This is what I have:

//My code
string cb1 = comboBox1.Items[comboBox1.SelectedIndex].ToString();

//Example 1
textBox2.Invoke((Action)(() => textBox2.Text = ""));

//Example 2
textbox2.Invoke((MethodInvoker)(delegate()
{
    //do something
}));

Answer 1

Try this one if you want to go with Example 1 (using a Func<string> delegate instead of an Action delegate):

string cb1 = comboBox1.Invoke((Func<string>) (() => comboBox1.Items[comboBox1.SelectedIndex].ToString())) as string;
