Assembly::GetTypes Method

Gets the types defined in this assembly.

Namespace:  System.Reflection
Assembly:  mscorlib (in mscorlib.dll)

public:
virtual array<Type^>^ GetTypes()

Return Value

Type: array<System::Type>
An array that contains all the types that are defined in this assembly.

Implements

_Assembly::GetTypes()

ExceptionCondition
ReflectionTypeLoadException

The assembly contains one or more types that cannot be loaded. The array returned by the Types property of this exception contains a Type object for each type that was loaded and nullptr for each type that could not be loaded, while the LoaderExceptions property contains an exception for each type that could not be loaded.

The returned array includes nested types.

If the GetTypes method is called on an assembly and a type in that assembly is dependent on a type in an assembly that has not been loaded (for example, if it derives from a type in the second assembly), a ReflectionTypeLoadException is thrown. For example, this can happen if the first assembly was loaded with the ReflectionOnlyLoad or ReflectionOnlyLoadFrom methods, and the second assembly was not loaded. It can also happen with assemblies loaded using the Load and LoadFile methods if the second assembly cannot be located when the GetTypes method is called.

NoteNote

If a type has been forwarded to another assembly, it is not included in the returned array. For information on type forwarding, see Type Forwarding in the Common Language Runtime.

The following example displays parameters of one method on a type in the specified assembly.


Assembly^ SampleAssembly;
SampleAssembly = Assembly::LoadFrom( "c:\\Sample.Assembly.dll" );
// Obtain a reference to a method known to exist in assembly.
MethodInfo^ Method = SampleAssembly->GetTypes()[ 0 ]->GetMethod( "Method1" );
// Obtain a reference to the parameters collection of the MethodInfo instance.
array<ParameterInfo^>^ Params = Method->GetParameters();
// Display information about method parameters.
// Param = sParam1
//   Type = System::String
//   Position = 0
//   Optional=False
for each ( ParameterInfo^ Param in Params )
{
   Console::WriteLine( "Param= {0}", Param->Name );
   Console::WriteLine( "  Type= {0}", Param->ParameterType );
   Console::WriteLine( "  Position= {0}", Param->Position );
   Console::WriteLine( "  Optional= {0}", Param->IsOptional );
}
