Reuse code from class to class

I have 2 winforms called AppNamespace.MYForm and AnotherNamespace.AnotherForm.
They both have a button.

When the user click on the button of AnotherNamespace.AnotherForm I would like to perform a click on the button located on AppNamespace.MYForm.

However, there is a constriant that AnotherNamespace cannot use AppNamespace.
This prevents me from doing : 

AppNamespace.MYForm firstForm = new AppNamespace.MYForm();
firstForm.button.PerformClick();

Any ideas?

Either make the Button on the second form public by editing the Form2.Designer.cs:

public System.Windows.Forms.Button button1;

And register its Click with the 1st Form: 

private void Form1_Load(object sender, EventArgs e)
{
    // or whatever you do to create the 2nd form..
    AnotherNamespace.Form2 F2 = new AnotherNamespace.Form2();
    F2.Show();
    // register the click:
    F2.button1.Click += button2_Click;
}

Or create a Property in the 2nd form:

public Button myButton { get; set;  }

And set it to the Button: 

public Form2()
{
   InitializeComponent();
   myButton = button1;
}

Now you can register its Click like this:

F2.myButton.Click += button2_Click;

Manually executing event of any control is a bad practice. Create separate method and execute it instead.

You can create interface then implement it to both forms. The interface should contains a method PerformClick.

public Interface IMyInterface
{
    void PerformClick(string _module);
}

public class Form1 : IMyInterface
{
   public void IMyInterface.PerformClick(string _module) 
   {
      //CODE HERE
      if (Application.OpenForms["Form2"] != null && _module != "Form2")
          ((IMyInterface)Application.OpenForms["Form2"]).PerformClick(_module);
   }

   private void button1_Click(object sender, EventArgs e)
   {
       this.PerformClick(this.Name);
   }
}


public class Form2 : IMyInterface
{
   public void IMyInterface.PerformClick() 
   {
      //CODE HERE
      if (Application.OpenForms["Form1"] != null && _module != "Form1")
          ((IMyInterface)Application.OpenForms["Form1"]).PerformClick(_module);
   }

   private void button1_Click(object sender, EventArgs e)
   {
       this.PerformClick(this.Name);
   }
}

Separate the button click code in a helper class/another namespace and call it in button click.

You can use the method in any namespace by calling helper namespace and method.
