.NET Framework Class Library

Gets the custom attributes for this assembly as specified by type.

[Visual Basic]
Overloads Public Overridable Function GetCustomAttributes( _
   ByVal attributeType As Type, _
   ByVal inherit As Boolean _
) As Object() Implements ICustomAttributeProvider.GetCustomAttributes
[C#]
public virtual object[] GetCustomAttributes(
 Type attributeType,
 bool inherit
);
[C++]
public: virtual Object* GetCustomAttributes(
 Type* attributeType,
 bool inherit
)  __gc[];
[JScript]
public function GetCustomAttributes(
   attributeType : Type,
 inherit : Boolean
) : Object[];

Parameters

attributeType: The Type for which the custom attributes are to be returned.
inherit: This argument is ignored for objects of type Assembly.

Return Value

An array of type Object containing the custom attributes for this assembly as specified by attributeType.

Implements

ICustomAttributeProvider.GetCustomAttributes

Exceptions

Exception Type	Condition
ArgumentNullException	attributeType is a null reference (Nothing in Visual Basic).
ArgumentException	attributeType is not a runtime type.

Remarks

This method implements the corresponding ICustomAttributeProvider interface method. Therefore, the inherit parameter must be specified even though it is ignored.

A pseudo-attribute indicates bits of the core metadata that must be set when the attribute is present. Unlike a custom attribute that extends the metadata for a type and is saved along with the type, a pseudo-attribute modifies the metadata for the type and then is discarded. Some of the resulting bits cannot be accessed using existing reflection APIs.

The following table summarizes the different pseudo-attributes and the accessors for the bits that are available in reflection.

Pseudo-Attribute	Metadata Bits	Reflection Accessor
DllImportAttribute	CorPInvokeMap DLL name	No accessor for PInvokeMap for ordinary method/global method attributes. No accessor for DLL name.
GuidAttribute	Stored as a real custom attribute.	Accessed as a real custom attribute.
ComImportAttribute	CorTypeAttr.tdImport	Type.Attributes.Import
SerializableAttribute	CorTypeAttr.tdSerializable	Type.Attributes.Serializable
NonSerializedAttribute	CorFieldAttr.fdNotSerialized	FieldInfo.Attributes.NotSerialized
MethodImplAttribute	CorMethodImpl	MethodInfo.GetMethodImplementationFlags() ConstructorInfo.GetMethodImplementationFlags()
MarshalAsAttribute	Various bits.	No accessor.
PreserveSigAttribute	CorMethodImpl.miOLE	MethodInfo.GetMethodImplementationFlags().OLE ConstructorInfo.GetMethodImplementationFlags().OLE
InAttribute	CorParamAttr.pdIn	ParameterInfo.Attributes.In
OutAttribute	CorParamAttr.pdOut	ParameterInfo.Attributes.Out
StructLayoutAttribute	CorTypeAttr.tdLayoutSequential CorTypeAttr.tdExplicitLayout CorTypeAttr.tdAnsiClass CorTypeAttr.tdUnicodeClass CorTypeAttr.tdAutoClass Class packing.	Type.Attributes.LayoutSequential Type.Attributes.ExplicitLayout Type.Attributes.AnsiClass Type.Attributes.UnicodeClass Type.Attributes.AutoClass No accessor.
FieldOffsetAttribute	Field offset.	No accessor.
AssemblyLoadAttribute	CorAssemblyFlags	No accessor or enumerator.
