Question

Gooday everyone.
1) I defined a public structure inside a class file (Films.cs) , like this:

public struct CategoryDetails
        {
            ...
        }

The class is NOT put into a namespace, for all that matters.

2) I have an aspx file called Catalog, with a code-behind file.
In the code-behind file, I have this (at the same level as the Page_Load method):

private void PopulateControls()
        {
            --> here I would like to have visibility to the CategoryDetails structure, which I don't
        }

I specify that the Catalog.ascx.cs (code-behind) file has a namespace.

• A. What I tried so far was to place the Films class inside the same
  namespace. No luck.
• B. As you can see, the structure is public. Thank you for your help.
  Much appreciated.

Answer 1

Try Films.CategoryDetails instead. Nested classes/structs need to have their wrapping class prefixed (like a namespace) when accessed. (unless you’re accessing it from within that wrapping class)

private void PopulateControls()
{
    var categorydetails = new Films.CategoryDetails();
    //do stuff
}

EDIT:
Just to clarify, from within the Films class, you no longer need to prefix it. (you still may prefix it if there are ambiguous naming issues):

namespace MyProject
{
    public class Films
    {
        public struct CategoryDetails
        {
        }


        public void DoStuff()
        {
            //both are valid
            var categorydetails = new CategoryDetails();
            var otherdetails = new Films.CategoryDetails();
        }

    }
}
