Note Note

To view the .NET Framework source code for this type, see the Reference Source. You can browse through the source code online, download the reference for offline viewing, and step through the sources (including patches and updates) during debugging; see instructions.

Type is the root of the System.Reflection functionality and is the primary way to access metadata. Use the members of Type to get information about a type declaration, such as the constructors, methods, fields, properties, and events of a class, as well as the module and the assembly in which the class is deployed.

The C# typeof operator (GetType operator in Visual Basic, typeid operator in Visual C++) returns a Type object.

A Type object that represents a type is unique; that is, two Type object references refer to the same object if and only if they represent the same type. This allows for comparison of Type objects using reference equality.

No permissions are required for code to use reflection to get information about types and their members, regardless of their access levels. No permissions are required for code to use reflection to access public members, or other members whose access levels would make them visible during normal compilation. However, in order for your code to use reflection to access members that would normally be inaccessible, such as private or internal methods, or protected fields of a type your class does not inherit, your code must have ReflectionPermission. See Security Considerations for Reflection.

Type is an abstract base class that allows multiple implementations. The system will always provide the derived class RuntimeType. In reflection, all classes beginning with the word Runtime are created only once per object in the system and support comparison operations.

Note Note

In multithreading scenarios, do not lock Type objects in order to synchronize access to static data. Other code, over which you have no control, might also lock your class type. This might result in a deadlock. Instead, synchronize access to static data by locking a private static object.

This class is thread safe; multiple threads can concurrently read from an instance of this type. An instance of Type can represent any of the following types:

  • Classes

  • Value types

  • Arrays

  • Interfaces

  • Pointers

  • Enumerations

  • Constructed generic types and generic type definitions

  • Type arguments and type parameters of constructed generic types, generic type definitions, and generic method definitions

A reference to the Type object associated with a type can be obtained in the following ways:

  • The Object.GetType method returns a Type object that represents the type of an instance.

  • The static GetType methods return a Type object that represents a type specified by its fully qualified name.

  • The Module.GetTypes, Module.GetType, and Module.FindTypes methods return Type objects that represent the types defined in a module. The first method can be used to obtain an array of Type objects for all the public and private types defined in a module. (You can obtain an instance of Module through the Assembly.GetModule or Assembly.GetModules method, or through the Type.Module property.)

  • The System.Reflection.Assembly object contains a number of methods to retrieve the classes defined in an assembly, including Assembly.GetType, Assembly.GetTypes, and Assembly.GetExportedTypes.

  • The FindInterfaces method returns a filtered list of interface types supported by a type.

  • The GetElementType method returns a Type object that represents the element.

  • The GetInterfaces and GetInterface methods return Type objects representing the interface types supported by a type.

  • The GetTypeArray method returns an array of Type objects representing the types specified by an arbitrary set of objects. The objects are specified with an array of type Object.

  • The GetTypeFromProgID and GetTypeFromCLSID methods are provided for COM interoperability. They return a Type object that represents the type specified by a ProgID or CLSID.

  • The GetTypeFromHandle method is provided for interoperability. It returns a Type object that represents the type specified by a class handle.

  • The C# typeof operator, the C++ typeid operator, and the Visual Basic GetType operator obtain the Type object for a type.

  • The MakeGenericType method returns a Type object representing a constructed generic type, which is an open constructed type if its ContainsGenericParameters property returns true, and a closed constructed type otherwise. A generic type can be instantiated only if it is closed.

  • The MakeArrayType, MakePointerType, and MakeByRefType methods return Type objects that represent, respectively, an array of a specified type, a pointer to a specified type, and the type of a reference parameter (ref in C#, ByRef in Visual Basic).

Note Note

A derived class can access protected members of the calling code's base classes. Also, access is allowed to assembly members of the calling code's assembly. As a rule, if you are allowed access in early-bound code, then you are also allowed access in late-bound code.

Note Note

Interfaces that extend other interfaces do not inherit the methods defined in the extended interfaces.

Notes to Inheritors

When you inherit from Type, you must override the following members: GUID, InvokeMember(String, BindingFlags, Binder, Object, Object[], ParameterModifier[], CultureInfo, String[]), Module, Assembly, TypeHandle, FullName, Namespace, AssemblyQualifiedName, BaseType, GetConstructorImpl, GetConstructors(BindingFlags), GetMethodImpl, GetMethods(BindingFlags), GetField(String, BindingFlags), GetFields(BindingFlags), GetInterface(String, Boolean), GetInterfaces(), GetEvent(String, BindingFlags), GetEvents(BindingFlags), GetPropertyImpl, GetProperties(BindingFlags), GetNestedType(String, BindingFlags), GetNestedTypes(BindingFlags), GetAttributeFlagsImpl, IsArrayImpl, IsByRefImpl, IsPointerImpl, IsPrimitiveImpl, IsCOMObjectImpl, GetElementType(), HasElementTypeImpl, UnderlyingSystemType, MemberInfo.Name, MemberInfo.IsDefined, MemberInfo.GetCustomAttributes(Boolean), and GetCustomAttributes.

The following code example shows a few representative features of Type. The C# typeof operator (GetType operator in Visual Basic, typeid operator in Visual C++) is used to get a Type object representing String. From this Type object, the GetMethod method is used to get a MethodInfo representing the Substring overload that takes a starting location and a length.

To identify the overload signature, the code example creates a temporary array containing two Type objects representing int (Integer in Visual Basic).

Note Note

To be precise, the array contains two references to the instance of Type that represents int in the current application domain. For any type, there is only one instance of Type per application domain.

The code example uses the MethodInfo to invoke the Substring method on the string "Hello, World!", and displays the result.

Imports System
Imports System.Reflection

Module Example

    Sub Main() 

        Dim t As Type = GetType(String)

        Dim substr As MethodInfo = t.GetMethod("Substring", _
            New Type() { GetType(Integer), GetType(Integer) })

        Dim result As Object = _ 
            substr.Invoke("Hello, World!", New Object() { 7, 5 })
        Console.WriteLine("{0} returned ""{1}"".", substr, result)

    End Sub  
End Module 

' This code example produces the following output: 

'System.String Substring(Int32, Int32) returned "World".
