How do I get a list of all loaded Types in C#?

I need to retrie开发者_JS百科ve all enums that were loaded from a given set of Assemblies.

List<Type> list = new List<Type>();
foreach (Assembly ass in AppDomain.CurrentDomain.GetAssemblies())
{
    foreach (Type t in ass.GetExportedTypes())
    {
        if (t.IsEnum)
        {
            list.Add(t);
        }
    }
}

That should do, for all assemblies loaded by the current Appdomain, to get just from defined assemblies, just adjust ;-)

Here is a more functional solution:

AppDomain.CurrentDomain.GetAssemblies()
    .SelectMany(a => a.GetTypes())
    .Where(t => t.IsEnum)

Assuming you have the list of Assembly objects you want to check:

IEnumerable<Assembly> assemblies; // assign the assemblies you want to check here

foreach (Assembly a in assemblies) {
    foreach (Type t in assembly.GetTypes()) {
        if (t.IsEnum) {
            // found an enum! Do whatever...
        }
    }
}

You should be able to use Assembly.GetTypes() to get all the types for the assembly. For each type, you can use Type.IsEnum property to see if it's an enum.

You can also use LINQ to return a list of all enum types from a list of assemblies.

IEnumerable<Assembly> assemblies;
// give assemblies some value
var enums = from assembly in assemblies let types = assembly.GetTypes() from type in types where type.IsEnum select type;

enums will be of type IEnumerable.
