Listing Folders in a List box with specific Subfolder - C#

I have a combobox with an array of Language codes - DA, DE , ET etc.

I have a directory with 11 folders listed from "A" to "K" and each of these folders contain 5 subfolders named after 5 random language codes

I want to be able to select a language in the combobox and click my search button and it will list me only the folders that have that specific language code folder in it

I want it to display the folder names in a listbox.

This is not a homework question - I am slowly learning C# and messing with different instances so i can understand them.

I have tried everything and cant get it to display.

This is what i have done thus far:

It is rather messy but Its all trial and error for me hence the stupid amount of comments

string Download = @"\\Mgsops\data\B&C_Poker_Builds\Release_Location\Tools\Language_Detection\DownloadBrands";

string DLLangs = @"\\Mgsops\data\B&C_Poker_Builds\Release_Location\Tools\Language_Detection\DownloadTrunk";


private int Total_Plus_EN = 0;

public Form1()
{
    InitializeComponent();


    DirectoryInfo languages = new DirectoryInfo(DLLangs);
    DirectoryInfo[] Dir = languages.GetDirectories();
    //languageBox.DataSource = Dir;
   //languageBox.SelectedIndex = 1;
   // languageBox.Items.RemoveAt(0);
    languageBox.Items.AddRange(Dir);
    languageBox.Items.RemoveAt(0);
    languageBox.SelectedIndex = 0;

    int Number = Dir.Length;
    //plus EN
    int Total_Plus_EN = 1 + Number;
    //Minus .SVN
    Total_Plus_EN = Total_Plus_EN - 1;
    string myString = Total_Plus_EN.ToString();
    textBox1.Text = myString;


}



private void button1_Click(object sender, EventArgs e)
{
    //Tried and tested 

    //IEnumerable<string> list = Directory.GetDirectories(Download).Where(s => s.Equals(languageBox.SelectedItem));
    //listBox4.DataSource = list.ToString();
    //for (int langIndex = 1; langIndex <= Total_Plus_EN; langIndex++)
    // {
    // }
    //string[] filesArray = Directory.GetFiles(Download);
    //listBox4.Items.AddRange(filesArray);

    listBox4.Items.Clear();

    string Local_Folder = @"\local";
    string backslash_Value = @"\";


    DirectoryInfo clients = new DirectoryInfo(Download);
    DirectoryInfo[] ClientNames = clients.GetDirectories();

    //listBox.DataSource = folders;          
   //  listBox4.Items.AddRange(ClientNames);
   // listBox4.Items.RemoveAt(0);

    string Destination_to_Lang = Download + backslash_Value + ClientNames + Local_Folder + backslash_Value + languageBox.SelectedItem ;

  //  DirectoryInfo langfolders = new DirectoryInfo(Destination_to_Lang);
    //DirectoryInfo[] PrintLang = langfolders.GetDirectories(languageBox.SelectedItem, SearchOption.AllDirectories);

    foreach (var d in Directory.GetDirectories(Destination_to_Lang))
    {
        var dirname = d.Substring(d.LastIndexOf('\'') + 1);
        listBox4.DataSource = dirname;
    }            
}}

I Have tried the above and some of the suggested below But i keep getting this error (Click above). I want it to search through the directories and list the folders which have subfolders named according to the ComboBox.SelectedItem()

The problem is in your foreach loop, You set your listbox's data source to your directory name.

If you want to set the datasource of your listbox, you should use a list. In your case you can add strings as items Like this :

foreach (var d in Directory.GetDirectories(Destination_to_Lang))
{
    var dirname = d.Substring(d.LastIndexOf('\'') + 1);
    listBox4.Items.Add(dirname);
}

In this case you should pay attention to clearing your listbox because if you use this code :

listBox4.DataSource = myList;

before filling the listbox, it will clear automaticly. But if you call 

 listBox.Items.Add(dirname);

It will dupplicate items if you call your methode more than one times.
