Assembly.GetCustomAttributes Method

Definition

Namespace:

System.Reflection

Assembly:

System.Runtime.dll

Gets the custom attributes for this assembly.

Overloads

GetCustomAttributes(Boolean)	Gets all the custom attributes for this assembly.
GetCustomAttributes(Type, Boolean)	Gets the custom attributes for this assembly as specified by type.

GetCustomAttributes(Boolean)

Source:

Assembly.cs

Gets all the custom attributes for this assembly.

public:
 virtual cli::array <System::Object ^> ^ GetCustomAttributes(bool inherit);

public virtual object[] GetCustomAttributes (bool inherit);

abstract member GetCustomAttributes : bool -> obj[]
override this.GetCustomAttributes : bool -> obj[]

Public Overridable Function GetCustomAttributes (inherit As Boolean) As Object()

Parameters

inherit

Boolean

This argument is ignored for objects of type Assembly.

Returns

Object[]

An array that contains the custom attributes for this assembly.

Implements

GetCustomAttributes(Boolean)

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.

GetCustomAttributes(Type, Boolean)

Source:

Assembly.cs

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

public:
 virtual cli::array <System::Object ^> ^ GetCustomAttributes(Type ^ attributeType, bool inherit);

public virtual object[] GetCustomAttributes (Type attributeType, bool inherit);

abstract member GetCustomAttributes : Type * bool -> obj[]
override this.GetCustomAttributes : Type * bool -> obj[]

Public Overridable Function GetCustomAttributes (attributeType As Type, inherit As Boolean) As Object()

Parameters

attributeType

Type

The type for which the custom attributes are to be returned.

inherit

Boolean

This argument is ignored for objects of type Assembly.

Returns

Object[]

An array that contains the custom attributes for this assembly as specified by attributeType.

Implements

GetCustomAttributes(Type, Boolean)

Exceptions

ArgumentNullException

attributeType is null.

ArgumentException

attributeType is not a runtime type.
