Return true per item if list1 contains part of any string from list2

Question

If a string(or part of a string) from list1 is the same as a string in list2 the string needs to be added to a listbox.

I now have:

            int g = 0;

            while (g < musthaves.Count())
            {
                if (list1.Contains(list2[g].ToString()))
                {
                    listBox14.Items.Add("Found: " + list2[g].ToString());
                }
                else
                {
                    listBox14.Items.Add("Not found: " + list2[g].ToString());
                }
                g++;
            }

The list are:

list1:
testcase scan document
testcase upload document
testcase delete document

list2:
upload document
scan document
indicate inconsistency

So the listbox should contain:

Found: upload document
Found: scan document
Not found: indicate inconsistency

But my results are Not found for every string.

Any help is appreciated.

You are checking only that full string is one of the item in the another list, but your requirement is

If a string (or part of a string) from list1 is the same as a string in list2

So you need to check every phrase in list2 if phrase contains one of the expected phrases from the list1 (uhh, I would suggest to use more descriptive names for variables - will simplify conversations :))

foreach (var requiredPhrase in list1)
{
    if (list2.Any(phrase => phrase.Contains(requiredPhrase))
    {
        // Found
    }
    else
    {
        // Not found
    }
}
