how do i check if the guid for the selected item is present in a list of guids?

[Added from OP "solution" post]

i have an expander with several tabs amd those tabs have similar items. when u drag and drop these items from the tab to a canvas each creates a guid and these guids gets saved into guid lists. each tab has a list for itself. example i drag n drop and object from tab 1 the guid for the item gets saved into the tab1 list n if its from the second tab guid gets saved into tab 2 list n so on. what i need to do now is when i select an item on the canvas i need a window to show the name of the tab it came from

What's the problem? What have you tried so far?
And I'm just curious: why some items have GUIDs and why checking them? I'm asking because there many cases of abusing them, or using without right purpose.

Don't post extra info as a solution: it removes the question from the "unanswered" list. Used the "Improve question" widget instead.

Solution 2

There is a Contains method which works with any class:List<T>.Contains[^]
Since Guid is a Value type, it will work with the default comparer.

C#

if (my list.Contains(guidToLookFor))
