int itemIndex = -1;
if ( collection->Contains( testStatement ) )

// Tests for the presence of a CodeStatement in the
// collection, and retrieves its index if it is found.
int itemIndex = -1;
if( collection.Contains( testStatement ) )
    itemIndex = collection.IndexOf( testStatement );

' Tests for the presence of a CodeStatement in the 
' collection, and retrieves its index if it is found.
Dim itemIndex As Integer = -1
If collection.Contains(testStatement) Then
    itemIndex = collection.IndexOf(testStatement)
