Properties

	Name	Description
	Attributes	Gets the attributes associated with this method.
	CallingConvention	Gets a value indicating the calling conventions for this method.
	ContainsGenericParameters	Gets a value indicating whether the generic method contains unassigned generic type parameters.
	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 indicating whether the method is abstract.
	IsAssembly	Gets a value indicating 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.
	IsConstructor	Gets a value indicating whether the method is a constructor.
	IsFamily	Gets a value indicating 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.
	IsFamilyAndAssembly	Gets a value indicating 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.
	IsFamilyOrAssembly	Gets a value indicating 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.
	IsFinal	Gets a value indicating whether this method is final.
	IsGenericMethod	Gets a value indicating whether the method is generic.
	IsGenericMethodDefinition	Gets a value indicating whether the method is a generic method definition.
	IsHideBySig	Gets a value indicating whether only a member of the same kind with exactly the same signature is hidden in the derived class.
	IsPrivate	Gets a value indicating whether this member is private.
	IsPublic	Gets a value indicating whether this is a public method.
	IsSecurityCritical	Gets a value that indicates whether the current method or constructor is security-critical or security-safe-critical at the current trust level, and therefore can perform critical operations.
	IsSecuritySafeCritical	Gets a value that indicates whether the current method or constructor is security-safe-critical at the current trust level; that is, whether it can perform critical operations and can be accessed by transparent code.
	IsSecurityTransparent	Gets a value that indicates whether the current method or constructor is transparent at the current trust level, and therefore cannot perform critical operations.
	IsSpecialName	Gets a value indicating whether this method has a special name.
	IsStatic	Gets a value indicating whether the method is static.
	IsVirtual	Gets a value indicating whether the method is virtual.
	MemberType	When overridden in a derived class, gets a MemberTypes value indicating the type of the member — method, constructor, event, and so on. (Inherited from MemberInfo.)
	MetadataToken	Gets a value that identifies a metadata element. (Inherited from MemberInfo.)
	MethodHandle	Gets a handle to the internal metadata representation of a method.
	MethodImplementationFlags	Gets the MethodImplAttributes flags that specify the attributes of a method implementation.
	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.)

Methods

	Name	Description
	Equals	Returns a value that indicates whether this instance is equal to a specified object. (Overrides MemberInfo.Equals(Object).) In XNA Framework 3.0, this member is inherited from Object.Equals(Object). In Portable Class Library Portable Class Library, this member is inherited from Object.Equals(Object).
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetCurrentMethod	Returns a MethodBase object representing the currently executing method.
	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.)
	GetCustomAttributesData	Returns a list of CustomAttributeData objects representing data about the attributes that have been applied to the target member. (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.
	GetHashCode	Returns the hash code for this instance. (Overrides MemberInfo.GetHashCode.) In XNA Framework 3.0, this member is inherited from Object.GetHashCode. In Portable Class Library Portable Class Library, this member is inherited from Object.GetHashCode.
	GetMethodBody	When overridden in a derived class, gets a MethodBody object that provides access to the MSIL stream, local variables, and exceptions for the current method.
	GetMethodFromHandle(RuntimeMethodHandle)	Gets method information by using the method's internal metadata representation (handle).
	GetMethodFromHandle(RuntimeMethodHandle, RuntimeTypeHandle)	Gets a MethodBase object for the constructor or method represented by the specified handle, for the specified generic type.
	GetMethodImplementationFlags	When overridden in a derived class, returns the MethodImplAttributes flags.
	GetParameters	When overridden in a derived class, gets the parameters of the specified method or constructor.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Invoke(Object, Object())	Invokes the method or constructor represented by the current instance, using the specified parameters.
	Invoke(Object, BindingFlags, Binder, Object(), CultureInfo)	When overridden in a derived class, invokes the reflected method or constructor with the given parameters.
	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.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
