gert all elememnts from class c# code example

Example 1: C# get all child classes of a class

//through reflection
using System.Reflection;

//as a reusable method/function
Type[] GetInheritedClasses(Type MyType) 
{
  	//if you want the abstract classes drop the !TheType.IsAbstract but it is probably to instance so its a good idea to keep it.
	return Assembly.GetAssembly(MyType).GetTypes().Where(TheType => TheType.IsClass && !TheType.IsAbstract && TheType.IsSubclassOf(MyType));
}

//or as a selection of a type in code.
Type[] ChildClasses Assembly.GetAssembly(typeof(YourType)).GetTypes().Where(myType => myType.IsClass && !myType.IsAbstract && myType.IsSubclassOf(typeof(YourType))));

//Example of usage
foreach (Type Type in
                Assembly.GetAssembly(typeof(BaseView)).GetTypes()
                .Where(TheType => TheType.IsClass && !TheType.IsAbstract && TheType.IsSubclassOf(typeof(BaseView))))
            {

                AddView(Type.Name.Replace("View", ""), (BaseView)Activator.CreateInstance(Type));
            }

Example 2: c# Get all class by namespace

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