C# error An object reference is required for the non-static

Question

In a C# 2008 solution file, there are 4 project files that interact with each other. While I am in the project file called 'app1', I want to be able to obtain the values in another project file called 'samples'.

When I am in debug looking at the locals window, I can see the value I want to obtain is in the following location: samples.PackageMetadata.SubCustomerNumber.

However I am getting the error: An object reference is required for the non-static field, method, or property 'samples.PackageMetadata.SubCustomerNumber.get'.

Thus can you show me code and tell me what I need to do so that I can obtain the 'SubCustomerNumber' value I need for an error message?
