如何使用来自另一个部分 class 的部分 class 中的方法

Question

I am working in an Excel file with Visual Studio and programming in C#. I added a listbox control to the sheet Seismic2D. I want to fill this listbox with information that is in the sheet FileList. The button that I am trying to program is in ribbon.

I tried to use Sis2D clase=new Sis2D(); but I got an error (There is no argument given that corresponds to the required formal parameter 'factory'of Sis2D.Sis2D(Factory,IServiceProvider)

In the Ribbon file...

public partial class Ribbon1
    {
       private void ListRefresh_Click(object sender, RibbonControlEventArgs e)
       {
           Excel.Worksheet wsFL = Globals.ThisWorkbook.Worksheets["FileList"];
           Sis2D clase = new Sis2D();
           clase.ListaFiles.Items.Add(wsFL.Range["A2"]);
           clase.ListaFiles.Items.Add(wsFL.Range["A3"]);
        }
    }

In the Sis2D.cs file

public partial class Sis2D

Another thing that I tried was adding this in Sis2D

public partial class Sis2D
{
public void LlenaListBox()
        {
           Excel.Worksheet wsFL = Globals.ThisWorkbook.Worksheets["FileList"];
           ListaFiles.Items.Add(wsFL.Range["A2"].Value);
           ListaFiles.Items.Add(wsFL.Range["A3"].Value);
        }
}

But I do not know how to call this method from the Ribbon partial class.

I want to be able to interact with the ListBox, adding items and reading them.

The error that 'There is no argument given that corresponds to the required formal

parameter 'factory'of Sis2D.Sis2D(Factory,IServiceProvider)' means that you only have the

following Constructor in the Sis2D class.

 public Sis2D(Factory, IServiceProvider)
        {
         ////////////

        }

If you want to access the method in Sis2D, you could add a empty constructor in Sis2D class. Like the following:

   public partial  class Sis2D
   {
    public Sis2D()  //  you need to add this code
    {
    }
    public void LlenaListBox()
    {
        Excel.Worksheet wsFL = Globals.ThisWorkbook.Worksheets["FileList"];
        ListaFiles.Items.Add(wsFL.Range["A2"].Value);
        ListaFiles.Items.Add(wsFL.Range["A3"].Value);
    }
    }

Then you could use the following code to access the method without throwing exception:

public partial  class Ribbon1
    {
        public void ListRefresh_Click()
        {
            Sis2D clase = new Sis2D();
            clase.LlenaListBox();

        }
    }

Answer 2

First I want to say thank you for all your help and interest in helping me. I want to apologize if possibly I was not clear with my question, because I am a beginner. Finally, what I wanted, filling the ListBox inside a worksheet from Visual Studio with C#, I got it.

In the Ribbon, the code for the button is:

C#
public partial class Ribbon1
{
private void FL_Click(object sender, RibbonControlEventArgs e)
   {
       Sis2D s = Globals.Sis2D;
       s.LlenaListBox();   
   }
}

In the sheet, the code is:

public partial class Sis2D 
{
public void LlenaListBox()
    {
            Excel.Worksheet wsFL = Globals.ThisWorkbook.Worksheets["Sheet1"];
            ListaF.Items.Add(wsFL.Range["A10"].Value);
            ListaF.Items.Add(wsFL.Range["A11"].Value);
            ListaF.Items.Add(wsFL.Range["A12"].Value);
    }
}

This is all. ListaF is a ListBox added to sheet1 into a worksheet from C# in Visual Studio. The following picture shows how the worksheet looks: enter image description here
