Definition

Discovers the attributes of a method and provides access to method metadata.

Remarks

The MethodInfo class represents a method of a type. You can use a MethodInfo object to obtain information about the method that the object represents and to invoke the method. For example:

You can instantiate a MethodInfo instances by calling the Type.GetMethods or Type.GetMethod method, or by calling the MethodInfo.MakeGenericMethod method of a MethodInfo object 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 IsGenericType property.

Constructors

MethodInfo()

Initializes a new instance of the MethodInfo class.

Properties

MemberType

Gets a MemberTypes value indicating that this member is a method.

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

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(Object)

Returns a value that indicates whether this instance is equal to a specified 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.

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.

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.

MakeGenericMethod(Type[])

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.

Operators

Equality(MethodInfo, MethodInfo)

Indicates whether two MethodInfo objects are equal.

Inequality(MethodInfo, MethodInfo)

Indicates whether two MethodInfo objects are not equal.

Explicit Interface Implementations

_MethodInfo.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.

_MethodInfo.GetType()

Provides access to the GetType() method from COM.

_MethodInfo.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.

_MethodInfo.GetTypeInfoCount(UInt32)

Retrieves the number of type information interfaces that an object provides (either 0 or 1).

_MethodInfo.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.
