C# Pull value from screen

We are using Epicor customization tools and need some help with passing a variable.  We know how to do it in VB but not C#   In the example below we are working on the private void epiButtonC1_Click(object sender, System.EventArgs args) event and will copycat to the other button click events once we find a solution.  There is a box on the screen where we are trying to get the information from it using the GUID and then pass it to the form we are opening.  The MessageBox in there is to check and see if the value shows up but that is not right either as it just shows "MyJob"
