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

Retrieving All Classes within a Namespace in C

Obtaining all classes within a specific namespace is essential in various scenarios. In C#, there are comprehensive approaches to accomplish this task.

To address this need, we'll explore a backward approach. By initially listing all types in an assembly and then scrutinizing the namespace of each type, we can effectively filter out the desired classes.

The following code snippet showcases this technique:

using System.Reflection;

private Type[] GetTypesInNamespace(Assembly assembly, string nameSpace)
{
    return assembly.GetTypes()
            .Where(t => String.Equals(t.Namespace, nameSpace, StringComparison.Ordinal))
            .ToArray();
}

To illustrate its usage, consider the following example:

Type[] typelist = GetTypesInNamespace(Assembly.GetExecutingAssembly(), "MyNamespace");
for (int i = 0; i < typelist.Length; i++)
{
    Console.WriteLine(typelist[i].Name);
}

In environments prior to .Net 2.0, where "Assembly.GetExecutingAssembly()" is unavailable, you'll require a workaround to retrieve the assembly as follows:

Assembly myAssembly = typeof(<Namespace>.<someClass>).GetTypeInfo().Assembly;
Type[] typelist = GetTypesInNamespace(myAssembly, "<Namespace>");
for (int i = 0; i < typelist.Length; i++)
{
    Console.WriteLine(typelist[i].Name);
}

By employing these methods, you can effectively enumerate all classes within a desired namespace in C#.
