Removing a specific string in the array using a List Array

Question

I am creating a simple Bingo game.

I stored the different number in a String Array

    String[] number = new[] { "" };
    
    if (lblLetter.Text == "B")
    {
        //number = new[] { "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15" };
    }
    if (lblLetter.Text == "I")
    {
        //number = new[] { "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29", "30" };
    }
    if (lblLetter.Text == "N")
    {
        //number = new[] { "31", "32", "33", "34", "35", "36", "37", "38", "39", "40", "41", "42", "43", "44", "45" };
    }
    if (lblLetter.Text == "G")
    {
        //number = new[] { "46", "47", "48", "49", "50", "51", "52", "53", "54", "55", "56", "57", "58", "59", "60" };
    }
    if (lblLetter.Text == "O")
    {
        number = new[] { "61", "62", "63", "64", "65", "66", "67", "68", "69", "70", "71", "72", "73", "74", "75" };
    }

I used a List Array to store the numbers that was already selected on the bingo thus should be removed on the String Array

public List<string> exceptions = new List<string>();

Appending the label Value to it

exceptions.Add(lblNumber.Text);

Now I want to remove specific Items on String Array that is found on the exceptions List String

I'm confused on how to do this, Any help will be appreciated.

The exceptions list string contains the numbers I want to remove on number list array — CSAPawn

You can use Except.

number = number.Except(exceptions).ToArray();
