Question

I have a List<FieldsInfo> in two different namespace say A & B both of them are in different project within same VS solution. I have populated some values for List<FieldsInfo> in namespace B. I want to pass this list to List<FieldsInfo> in namespace B to assign value to ListBox control. Please suggest me how can I achieve this.

Answer 1

There is nothing related between A.FieldsInfo and B.FieldsInfo. The ideal would be to make them only a single type. If that isn’t possible, then a lazy compromise is to declare an IFieldsInfo somewhere (with the common members), and implement IFieldsInfo from both types. One nice thing about this is that implicit interface implementation will kick in, and partial classes make it possible to do this even for generated types outside your control:

namespace A {
    partial class FieldsInfo : IFieldsInfo {}
}
namespace B {
    partial class FieldsInfo : IFieldsInfo {}
}

Now just talk in terms if IFieldsInfo instead of either A.FieldsInfo or B.FieldsInfo.
