The MethodInfo type exposes the following members.

Properties

Name Description
Attributes Gets the attributes associated with this method. (Inherited from MethodBase.)
CallingConvention Gets a value that indicates the calling conventions for this method. (Inherited from MethodBase.)
ContainsGenericParameters Gets a value that indicates whether the generic method contains unassigned generic type parameters. (Inherited from MethodBase.)
CustomAttributes Gets a collection that contains this member's custom attributes. (Inherited from MemberInfo.)
DeclaringType Gets the class that declares this member. (Inherited from MemberInfo.)
IsAbstract Gets a value that indicates whether the method is abstract (MustInherit in Visual Basic). (Inherited from MethodBase.)
IsAssembly Gets a value that indicates whether the potential visibility of this method or constructor is described by MethodAttributes..::.Assembly; that is, the method or constructor is visible at most to other types in the same assembly, and is not visible to derived types outside the assembly. (Inherited from MethodBase.)
IsConstructor Gets a value that indicates whether the method is a constructor. (Inherited from MethodBase.)
IsFamily Gets a value that indicates whether the visibility of this method or constructor is described by MethodAttributes..::.Family; that is, the method or constructor is visible only within its class and derived classes. (Inherited from MethodBase.)
IsFamilyAndAssembly Gets a value that indicates whether the visibility of this method or constructor is described by MethodAttributes..::.FamANDAssem; that is, the method or constructor can be called by derived classes, but only if they are in the same assembly. (Inherited from MethodBase.)
IsFamilyOrAssembly Gets a value that indicates whether the potential visibility of this method or constructor is described by MethodAttributes..::.FamORAssem; that is, the method or constructor can be called by derived classes wherever they are, and by classes in the same assembly. (Inherited from MethodBase.)
IsFinal Gets a value that indicates whether this method is final (NotOverridable in Visual Basic). (Inherited from MethodBase.)
IsGenericMethod Gets a value that indicates whether the method is generic. (Inherited from MethodBase.)
IsGenericMethodDefinition Gets a value that indicates whether the method is a generic method definition. (Inherited from MethodBase.)
IsHideBySig Gets a value that indicates whether only a member of the same kind with exactly the same signature is hidden in the derived class. (Inherited from MethodBase.)
IsPrivate Gets a value that indicates whether this member is private. (Inherited from MethodBase.)
IsPublic Gets a value that indicates whether this is a public method. (Inherited from MethodBase.)
IsSpecialName Gets a value that indicates whether this method has a special name. (Inherited from MethodBase.)
IsStatic Gets a value that indicates whether the method is static (Shared in Visual Basic). (Inherited from MethodBase.)
IsVirtual Gets a value that indicates whether the method is virtual (Overridable in Visual Basic). (Inherited from MethodBase.)
MemberType Gets a MemberTypes value indicating that this member is a method. (Overrides MemberInfo..::.MemberType.)
MetadataToken Gets a value that identifies a metadata element. (Inherited from MemberInfo.)
MethodHandle Gets a handle to the internal metadata representation of a method. (Inherited from MethodBase.)
MethodImplementationFlags Gets the MethodImplAttributes flags that specify the attributes of a method implementation. (Inherited from MethodBase.)
Module Gets the module in which the type that declares the member represented by the current MemberInfo is defined. (Inherited from MemberInfo.)
Name Gets the name of the current member. (Inherited from MemberInfo.)
ReflectedType Gets the class object that was used to obtain this instance of MemberInfo. (Inherited from MemberInfo.)
ReturnParameter Gets a ParameterInfo object that contains information about the return type of the method, such as whether the return type has custom modifiers.
ReturnType Gets the return type of this method.
ReturnTypeCustomAttributes Gets the custom attributes for the return type.

Methods

Name Description
CreateDelegate(Type) Creates a delegate of the specified type from this method.
CreateDelegate(Type, Object) Creates a delegate of the specified type with the specified target from this method.
Equals Returns a value that indicates whether this instance is equal to a specified object. (Overrides MethodBase..::.Equals(Object).)
Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
GetBaseDefinition When overridden in a derived class, returns the MethodInfo object for the method on the direct or indirect base class in which the method represented by this instance was first declared.
GetCustomAttributes(Boolean) When overridden in a derived class, returns an array of all custom attributes applied to this member. (Inherited from MemberInfo.)
GetCustomAttributes(Type, Boolean) When overridden in a derived class, returns an array of custom attributes applied to this member and identified by Type. (Inherited from MemberInfo.)
GetGenericArguments Returns an array of Type objects that represent the type arguments of a generic method or the type parameters of a generic method definition. (Overrides MethodBase..::.GetGenericArguments()()().)
GetGenericMethodDefinition Returns a MethodInfo object that represents a generic method definition from which the current method can be constructed.
GetHashCode Returns the hash code for this instance. (Overrides MethodBase..::.GetHashCode()()().)
GetMethodImplementationFlags When overridden in a derived class, returns the MethodImplAttributes flags. (Inherited from MethodBase.)
GetParameters When overridden in a derived class, gets the parameters of this method or constructor. (Inherited from MethodBase.)
GetType Gets the Type of the current instance. (Inherited from Object.)
Invoke(Object, array<Object>[]()[]) Invokes the method or constructor represented by the current instance, using the specified parameters. (Inherited from MethodBase.)
Invoke(Object, BindingFlags, Binder, array<Object>[]()[], CultureInfo) When overridden in a derived class, invokes the reflected method or constructor with the given parameters. (Inherited from MethodBase.)
IsDefined When overridden in a derived class, indicates whether one or more attributes of the specified type or of its derived types is applied to this member. (Inherited from MemberInfo.)
MakeGenericMethod Substitutes the elements of an array of types for the type parameters of the current generic method definition, and returns a MethodInfo object representing the resulting constructed method.
MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
ToString Returns a string that represents the current object. (Inherited from Object.)

Remarks

Instances of MethodInfo are obtained by calling the GetMethods or GetMethod method of a Type object or of an object that derives from Type, or by calling the MakeGenericMethod method of a MethodInfo that represents a generic method definition.

For a list of the invariant conditions for terms specific to generic methods, see the IsGenericMethod property. For a list of the invariant conditions for other terms used in generic reflection, see the Type..::.IsGenericType property.

In Windows Phone applications, you cannot derive new types from MethodInfo.
