C# Create a new array from 2 existing arrays

[Skenderbeu]

I have a method where I would like to fill texboxes with a code dependant on options selected from 5 dropdownlists.

Each of the ddls has options 1-5 these are stored in wgselect, wghidden stores the string code assigned to each ddl. If option 3 is selected on ddl selCooker then i need 3 textboxes to be filled with string 77. If selFridge option 1 is slected at the same time then 78 needs to be added to textbox 4.

Any idea how to achieve this?

Is the code i have below - so far I can only fill all 5 boxes with the code associated with the last option selected.

protected void button1_Click(object sender, EventArgs e)
    {
        DropDownList[] wgselect = { selCooker, selFridge, selDryer, selDishwasher, selTV };
                string[] wghidden = {"77","78","79","80","81"};
        string[] wgcodes = new string[5];
 
        int wgsel = wgselect.Length;
               int i = 0;
                int u = 0;
                   for (; i < wgsel; i++)
        {
            if (wgselect[i].SelectedItem.Value != "")
            {
 
              u = u+i
            }
            wgcodes[0] = wghidden[u];
            wgcodes[1] = wghidden[u];
            wgcodes[2] = wghidden[u];
            wgcodes[3] = wghidden[u];
            wgcodes[4] = wghidden[u];
 
        }
 
        dfh1.Text = wgcodes[0];
        dfh2.Text = wgcodes[1];
        dfh3.Text = wgcodes[2];
        dfh4.Text = wgcodes[3];
        dfh5.Text = wgcodes[4];
