Parameters

Type	Name	Description
Type	attributeType	The type of custom attribute to search for. The search includes derived types.
bool	inherit	true to search this member's inheritance chain to find the attributes; otherwise, false. This parameter is ignored for properties and events.

Returns

Type	Description
bool	true if one or more instances of attributeType or any of its derived types is applied to this member; otherwise, false.

Overrides

MemberInfo.IsDefined(Type, bool)

IsPointerImpl()

When overridden in a derived class, implements the IsPointer property and determines whether the Type is a pointer.

Declaration

protected override bool IsPointerImpl()

Returns

Type	Description
bool	true if the Type is a pointer; otherwise, false.

Overrides

Type.IsPointerImpl()

IsPrimitiveImpl()

When overridden in a derived class, implements the IsPrimitive property and determines whether the Type is one of the primitive types.

Declaration

protected override bool IsPrimitiveImpl()

Returns

Type	Description
bool	true if the Type is one of the primitive types; otherwise, false.

Overrides

Type.IsPrimitiveImpl()

MakeArrayType()

Returns a Type object representing a one-dimensional array of the current type, with a lower bound of zero.

Declaration

public override Type MakeArrayType()

Returns

Type	Description
Type	A Type object representing a one-dimensional array of the current type, with a lower bound of zero.

Overrides

Type.MakeArrayType()

Exceptions

Type	Condition
NotSupportedException	The invoked method is not supported in the base class. Derived classes must provide an implementation.
TypeLoadException	The current type is TypedReference. -or- The current type is a ByRef type. That is, IsByRef returns true.

MakeByRefType()

Returns a Type object that represents the current type when passed as a ref parameter (ByRef parameter in Visual Basic).

Declaration

public override Type MakeByRefType()

Returns

Type	Description
Type	A Type object that represents the current type when passed as a ref parameter (ByRef parameter in Visual Basic).

Overrides

Type.MakeByRefType()

Exceptions

Type	Condition
NotSupportedException	The invoked method is not supported in the base class.
TypeLoadException	The current type is TypedReference. -or- The current type is a ByRef type. That is, IsByRef returns true.

MakeGenericType(params Type[])

Substitutes the elements of an array of types for the type parameters of the current generic type definition and returns a Type object representing the resulting constructed type.

Declaration

public override Type MakeGenericType(params Type[] typeArguments)

Parameters

Type	Name	Description
Type[]	typeArguments	An array of types to be substituted for the type parameters of the current generic type.

Returns

Type	Description
Type	A Type representing the constructed type formed by substituting the elements of typeArguments for the type parameters of the current generic type.

Overrides

Type.MakeGenericType(params Type[])

Exceptions

Type	Condition
InvalidOperationException	The current type does not represent a generic type definition. That is, IsGenericTypeDefinition returns false.
ArgumentNullException	typeArguments is null. -or- Any element of typeArguments is null.
ArgumentException	The number of elements in typeArguments is not the same as the number of type parameters in the current generic type definition. -or- Any element of typeArguments does not satisfy the constraints specified for the corresponding type parameter of the current generic type. -or- typeArguments contains an element that is a pointer type (IsPointer returns true), a by-ref type (IsByRef returns true), or void.
NotSupportedException	The invoked method is not supported in the base class. Derived classes must provide an implementation.

ToString()

Returns a String representing the name of the current Type.

Declaration

public override string ToString()

Returns

Type	Description
string	A string representing the name of the current Type.

Overrides

Type.ToString()
