AssemblyDelaySignAttribute Class


Specifies that the assembly is not fully signed when created.

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


[AttributeUsageAttribute(AttributeTargets.Assembly, Inherited = false)]
public sealed class AssemblyDelaySignAttribute : Attribute


Initializes a new instance of the AssemblyDelaySignAttribute class.


Gets a value indicating the state of the attribute.


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


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.)


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


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


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


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


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

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.)


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.)

When this attribute is used on an assembly, space is reserved for the signature which is later filled by a signing tool such as the Sn.exe utility. Delayed signing is used when the author of the assembly does not have access to the private key that will be used to generate the signature, as in [assembly:AssemblyDelaySignAttribute(true)].

The classes in System.Runtime.CompilerServices are intended for use by compilers only. Do not use them unless you are building a compiler.

For more information, see the Common Language Infrastructure (CLI) documentation, especially "Partition II: Metadata Definition and Semantics". The documentation is available online; see ECMA C# and Common Language Infrastructure Standards on MSDN and Standard ECMA-335 - Common Language Infrastructure (CLI) on the Ecma International Web site.

The following code example shows the use of the AssemblyDelaySignAttribute attribute with the AssemblyKeyFileAttribute. To compile this example, you must create a strong-name key file named TestPublicKey.snk using the Sn.exe (Strong Name Tool):

sn -k TestPublicKey.snk 

Compile the example as a .dll. If you compile from the command line, use the /t:library option for C# or Visual Basic, or the /LD linker option for Visual C++.
