array<CodeAttributeArgument^>^temp3 = {gcnew CodeAttributeArgument( gcnew CodePrimitiveExpression( "Test Description" ) )};
CodeAttributeDeclaration^ testdeclaration = gcnew CodeAttributeDeclaration( "DescriptionAttribute",temp3 );
int itemIndex = -1;
if ( collection->Contains( testdeclaration ) )
   itemIndex = collection->IndexOf( testdeclaration );

// Tests for the presence of a CodeAttributeDeclaration in
// the collection, and retrieves its index if it is found.
CodeAttributeDeclaration testdeclaration = new CodeAttributeDeclaration("DescriptionAttribute", new CodeAttributeArgument(new CodePrimitiveExpression("Test Description")) );
int itemIndex = -1;
if( collection.Contains( testdeclaration ) )
    itemIndex = collection.IndexOf( testdeclaration );

' Tests for the presence of a CodeAttributeDeclaration in the 
' collection, and retrieves its index if it is found.
Dim testdeclaration As New CodeAttributeDeclaration("DescriptionAttribute", New CodeAttributeArgument(New CodePrimitiveExpression("Test Description")))
Dim itemIndex As Integer = -1
If collection.Contains(testdeclaration) Then
