How Can I Retrieve All Classes Within a Specific Namespace Using C# Reflection?

Use reflection to enumerate namespace types

Reflection allows developers to inspect loaded assemblies and manipulate metadata. In C#, you can query information about types defined in a specific namespace.

Get namespace type

To retrieve all classes in a namespace using reflection, follow these steps:

1. Use a string variable to identify the target namespace.
2. Use Assembly.GetExecutingAssembly().GetTypes() to iterate over the types loaded in the executing assembly.
3. Use LINQ to filter the results, specifying that the type should be a class with a matching namespace.
4. Convert the filtered enum to a list using ToList().
5. Use a loop to iterate over the list and print the name of the class.

Sample code

Here is a sample code snippet illustrating this approach:

<code class="language-csharp">string nspace = "...";

var q = from t in Assembly.GetExecutingAssembly().GetTypes()
        where t.IsClass && t.Namespace == nspace
        select t;

q.ToList().ForEach(t => Console.WriteLine(t.Name));</code>

This code will print the names of all classes defined in the specified namespace in the current assembly. Note that this method only considers the executing assembly, so if your namespace is spread across multiple assemblies, you will need to enumerate all loaded assemblies to get a complete list of types.
