Help with lambda expression

Question

Hi,

I have a string array Array1 and a string array A2. I want to combine these in a 3rd array A3 but excluding duplicate values. Can this be done through lambda expressions or only through iterating through the array and checking array.Contains()?

Thanks.

Answer 1

You can do the following

Dim newArray = array1.Union(array2).Distinct().ToArray()

This requires Visual Studio 2008 or higher (VB.Net 9.0).

Answer 2

array1.Union(array2).Distinct().ToArray();
