Static context error

I can't figure out what could be static here to cause that error below: 

public bool OptionsMatch(Item item, ItemFavorite itemFavorite)
{
    bool isSame = true;

    switch (item.DispType)
    {
        case DispType.Dropdown:
        case DispType.Radio:
            isSame = String.Contains(item.Value);
            break;
        case DispType.ImageList:
            isSame = ListValuesMatch(item, itemFavorite);
            break;
    }

    return isSame;
}

Error: Cannot access non-static method 'Contains' in static context

DispType is an enum. And the rest are all non-static concrete type instances as well as the underlying class is not static either that contains this method.

Here's the problem which occurs:

isSame = String.Contains(item.Value);

Contains is an instance method:

isSame = "foo".Contains(item.Value);

or the other way around depending on what you are trying to do:

isSame = item.Value.Contains("foo");

The method Contains on System.String is an instance method. You're trying to access using the type System.String which is an error. You'll need an instance of string.

String.Contains is not a valid static method. What are you trying to evaluate?

string.Contains is not static, it is an instance method; i.e. it is called on an instance of a string, like so:

"something".Contains(item.Value);

This is because Contains requires two objects - the reference string, and the string to search for. You've only provided one (the string to search for) but not where to look.
