How to compare two textbox alphanumeric values with each other in c# WinForm

private void yourTextBox_TextChanged(object sender, EventArgs e)
{
    string value1 = textBox1.Text;
    string value2 = textBox2.Text; // change the names here

    // now you can compare value1 and value2 the way you want, for example:
    if (value1 == value2)
    {
        // text is equal
    }
    else
    {
        // text is not equal
    }
}
