Array of structure

[Leon]

Hi Everybody

I have a small structure
Structure SkuInfo
Dim SkuNo As String
Dim Priority As Integer
End Structure
and Array

Dim arrSkus() As SkuInfo

Before adding next element to this array I want to make sure
that I do not have elements with the same SKUNO.

I am trying to use indexof, but do not know how to use it with array of
structures.
I realize I can use For... Next loop, but hope there is a better way to do
this.

Thanks in advance

Thank you Mark.
I'll try that.

Firstly, I would not use an array for this. Instead, I'd use a Dictionary
generic. Generics were introduced in .NET Framework v2, and are many times
more powerful and function-rich than arrays. A Dictionary would allow you to
add the structure *and* reference it by its SkuNo:

Alternatively, you could use (probably) use LINQ to query the array:

However, the generic method will be much simpler, and probably much
faster...
