If you can't read my code, try converting it here[^]

string sources = @"
        using System;
        public static class ExampleClass
        {
            public static void ExampleMethod()
            {
                Console.WriteLine(""Hello World!"");
            }
        }";

string st = something

if (textBox1.Text == "Jon" && chkText.Checked)
                MessageBox.Show(st + " (if)");
            else
                MessageBox.Show(st + " (else)");"
