c# - How to find out if there are any duplicates in one list versus another? -
I have a list where a property of Myclass is 'name'. I want to know that duplicates with the same name in the list Myclass is.
In addition, I have a separate list and I want to know whether there is a duplicate in comparison to List A or not.
To answer the first question
I want to know Whether the duplicate is the list with the same name in the Myclass.
You can do this:
boolHyplicates = List A. Calculation! = Listings Select (C = & gt; c.Name) .Distinct () Count ();
In response to another question
In addition, I have a separate list and I want to know that there is no duplicate compared to List A I
You can:
bool headlinks = separate list Select (c = & gt; c.Name). Sort (Select List (c = & gt; C.Name)). anyone ();
