How to exclude an array from search in C#

Question

I've an array. Let's say;

private string[] WhiteList =
{
"abcxyz.cs",
"mouseapi.dll",
"SensitivtyFix.asi",
"drake.mp3"
};

Another array,

private string[] SuspectedFiles =
{
".cs",
"d3d9.dll",
"sqlite3.dll",
"mod_sa.ini",
"mod_sa.raw",
".cleo",
".asi"
};

Now I want to exclude WhiteList array from a directory/file search. How do I achieve that?

For this search, I'm using another array called SuspectedFiles as mentioned above from which I could fetch desired files but I'm unable to exclude files from the array Whitelist.

This is my code;

 

 I could get results of files from SuspectedFiles array but couldn't remove files contained in Whitelist array from the search results.

private void VerifySuspectedFiles()
        {
            listBox1.Enabled = true;

            DirectoryInfo DirInf = new DirectoryInfo(GetGtaRegistryPath());
            int GetSize = SuspectedFiles.GetLength(0);

            if (!DirInf.Exists)
            {
                MessageBox.Show("This directory does not exist!", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);

                return;
            }

            if (GetSize == 0)
            {
                return;
            }

            for (int i = 0; i < GetSize; ++i)
            {
                foreach (var File in DirInf.GetFiles("*", SearchOption.AllDirectories))
                {
                    if (File.FullName.Contains(SuspectedFiles[i]) && !File.FullName.Contains(WhiteList[i]))

                    {
                        listBox1.Items.Add("File: " + File.FullName);
                    }
                }
            }
        }

 

Any help would be great. Thank You.
