c# constructor issues

Question

Ok hello sharpcorner 

 

i been having a issue now for ages and cant seem to find out why its causing me issues  but here is a lines of the code 

 

Ok main form1

elfenlied_program_settings elf;
addingweapons elf_weap;
Parser elfenliedl;
gscadding elfy1;


//Parser parser = new Parser("model1887_sp");



public Form1()
{

    InitializeComponent();

    updater1.CheckForUpdates();
    listBoxAdv1.Visible = false;
    elf = new elfenlied_program_settings(listBoxAdv1,elfenliedl);
    elf_weap = new addingweapons(richTextBoxEx1);
    elfenliedl = new Parser("model1887_sp");
    elfy1 = new gscadding(this, elf_weap);
    elfy1.elfygsc = this;
    timer1.Start();
    elf.buttonX2 = buttonX2;
    elf.elfenform = this;
   // elfe.elfgsc = this;
    buttonX2.Visible = false;
    buttonX3.Enabled = true;
    textBoxX6.Enabled = false;
    elfenliedl.buttonX1 = buttonX1;

    // last thing to add hopfully

    if (Properties.Settings.Default.root.Equals("First"))
    {
        if (Directory.Exists(wawpath))
        {
            Properties.Settings.Default.root.Equals(wawpath);
            string rootsave = wawpath;
            Properties.Settings.Default.root = rootsave;
            Properties.Settings.Default.Save();
            listBoxAdv1.Visible = true;
            root = Properties.Settings.Default.root;
            buttonX2.Visible = true;
            elf.newlistbox();
            elf.listboxfunction();
            updatesettings();

        }
    }
    else
    {
        MessageBox.Show("we did not hit it");
    }


}

the methord i want to reach in form1  

 

public void updatesettings()
{
    mods = Properties.Settings.Default.mods + "//maps//_zombiemode_weapons.gsc";
    dlc3code = Properties.Settings.Default.mods + "//maps//dlc3_code.gsc";
    zombiemodeweapons = Properties.Settings.Default.mods + "//maps//_zombiemode_weapons.gsc";
}

 

and what im trying to do is get gscadder to revrence  form 1 to update string paths as follows here 

 

gscadding
 and i want here to revrence updatesettings in form1

 

public SoundAlis sounds;
public addingweapons dlc3gsc;
public Form1 elfygsc;
public gscadding(addingweapons dlc3)
{
    dlc3gsc = dlc3;
}

public gscadding(Form1 elfygsc,addingweapons dlc3)
{
    this.elfygsc = elfygsc;
}
/// <summary>
/// MODEL 1887 DLC3....
/// </summary>
public void dlcexists()
{

    elfygsc.updatesettings();
    if (dlc3gsc.Model1887 == true)
    {
        if (File.Exists(dlc3code))
        {
            MessageBox.Show("exists");
        }
        else
        {
            DialogResult dialogResult = MessageBox.Show("Dlc3code.gsc is not found in mods do you wish to copy.", "Dlc3_code.gsc not found in mods", MessageBoxButtons.YesNo);
            if (dialogResult == DialogResult.Yes)
            {
                File.Copy(Properties.Settings.Default.root + "\\raw\\maps\\dlc3_code.gsc", Properties.Settings.Default.mods + "//maps//dlc3_code.gsc", true);
                {
                    string s = "include_weapon( \"model1887_sp\");"; //string s = "include_weapon( \"hk416_zm\");";

                    string file = modspath1 + "//maps//dlc3_code.gsc";
                    List<string> lines = new List<string>(System.IO.File.ReadAllLines(file));
                    int index = lines.FindLastIndex(item => item.Contains(("include_weapon(")));
                    if (index != -1)
                    {
                        lines.Insert(index + 1, s);//""
                    }
                    System.IO.File.WriteAllLines(file, lines);
                    MessageBox.Show("done");
                }
            }

            else if (dialogResult == DialogResult.No)
            {
                MessageBox.Show("No Files Copied To Add files to the mystery box you will need to add lines later");
            }
        }
    }

 and i do have a call in another class im not sure if this is what is causing it or not but i dont think so as that one revrences the form1 as well 

 

addingweapons.cs

 

SoundAlis sounds;
gscadding elfgscadd;
public bool M27 { get; set; }
public bool Model1887 { get; set; }




// copying files
private void DirectoryCopy(
string sourceDirName, string destDirName, bool copySubDirs)
{
    DirectoryInfo dir = new DirectoryInfo(sourceDirName);
    DirectoryInfo[] dirs = dir.GetDirectories();

    // If the source directory does not exist, throw an exception.
    if (!dir.Exists)
    {
        throw new DirectoryNotFoundException(
            "Source directory does not exist or could not be found: "
            + sourceDirName);
    }

    // If the destination directory does not exist, create it.
    if (!Directory.Exists(destDirName))
    {
        Directory.CreateDirectory(destDirName);
    }


    // Get the file contents of the directory to copy.
    FileInfo[] files = dir.GetFiles();

    foreach (FileInfo file in files)
    {
        // Create the path to the new copy of the file.
        string temppath = Path.Combine(destDirName, file.Name);

        // Copy the file.
        file.CopyTo(temppath, true);
    }

    // If copySubDirs is true, copy the subdirectories.
    if (copySubDirs)
    {

        foreach (DirectoryInfo subdir in dirs)
        {
            // Create the subdirectory.
            string temppath = Path.Combine(destDirName, subdir.Name);

            // Copy the subdirectories.
            DirectoryCopy(subdir.FullName, temppath, copySubDirs);
        }
    }
}

public addingweapons(DevComponents.DotNetBar.Controls.RichTextBoxEx richtextboxelf)
{

    richTextBoxEx1 = richtextboxelf;
   // opnwep = new Parser(this);
    elfgscadd = new gscadding(this);
    sounds = new SoundAlis(this, elfgscadd);
    elfgscadd.sounds = sounds;


    // textboxes






}

 And this is the error i get once i push copy weapons 

 

 

 

Thank you in advance Saito
