AssemblyFlagsAttribute Class

 

Specifies a bitwise combination of AssemblyNameFlags flags for an assembly, describing just-in-time (JIT) compiler options, whether the assembly is retargetable, and whether it has a full or tokenized public key. This class cannot be inherited.

Namespace:   System.Reflection
Assembly:  mscorlib (in mscorlib.dll)

public sealed class AssemblyFlagsAttribute : Attribute

NameDescription
System_CAPS_pubmethodAssemblyFlagsAttribute(AssemblyNameFlags)

Initializes a new instance of the AssemblyFlagsAttribute class with the specified combination of AssemblyNameFlags flags.

System_CAPS_pubmethodAssemblyFlagsAttribute(Int32)

Obsolete.Initializes a new instance of the AssemblyFlagsAttribute class with the specified combination of AssemblyNameFlags flags, cast as an integer value.

System_CAPS_pubmethodAssemblyFlagsAttribute(UInt32)

Obsolete.Initializes a new instance of the AssemblyFlagsAttribute class with the specified combination of AssemblyNameFlags flags, cast as an unsigned integer value.

NameDescription
System_CAPS_pubpropertyAssemblyFlags

Gets an integer value representing the combination of AssemblyNameFlags flags specified when this attribute instance was created.

System_CAPS_pubpropertyFlags

Obsolete.Gets an unsigned integer value representing the combination of AssemblyNameFlags flags specified when this attribute instance was created.

System_CAPS_pubpropertyTypeId

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

NameDescription
System_CAPS_pubmethodEquals(Object)

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_pubmethodGetHashCode()

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodIsDefaultAttribute()

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethodMatch(Object)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfoCount(UInt32)

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

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

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

The AssemblyNameFlags enumeration describes the assembly characteristics that can be set using this attribute.

To access the flags that have been specified for an assembly, use the Assembly.GetName property to obtain an AssemblyName object, then use the AssemblyName.Flags property to obtain an AssemblyNameFlags value.

To specify AssemblyNameFlags flags for a dynamic assembly, set the AssemblyName.Flags property of the AssemblyName object that you pass to the AppDomain.DefineDynamicAssembly method.

The following code example shows how to apply the AssemblyFlagsAttribute to an assembly, and how to read the flags at run time. The example also creates an instance of the attribute, and uses the AssemblyFlags property to display the flags. For an example of how to apply the AssemblyFlagsAttribute to a dynamic assembly, see the AssemblyName.Flags property.

        ListFlags(thisAsmName.Flags);

        // Create an instance of AssemblyFlagsAttribute with the
        // same combination of flags that was specified for this

        // the return value must be cast to AssemblyNameFlags.
        AssemblyNameFlags anf = (AssemblyNameFlags) afa.AssemblyFlags;

        // Display the flags.
