AssemblyKeyFileAttribute Class

Specifies the name of a file containing the key pair used to generate a strong name.

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

[AttributeUsageAttribute(AttributeTargets::Assembly, Inherited=false)] 
[ComVisibleAttribute(true)] 
public ref class AssemblyKeyFileAttribute sealed : public Attribute
/** @attribute AttributeUsageAttribute(AttributeTargets.Assembly, Inherited=false) */ 
/** @attribute ComVisibleAttribute(true) */ 
public final class AssemblyKeyFileAttribute extends Attribute
AttributeUsageAttribute(AttributeTargets.Assembly, Inherited=false) 
ComVisibleAttribute(true) 
public final class AssemblyKeyFileAttribute extends Attribute

When building a strong-named assembly, the author must supply either this attribute or AssemblyKeyNameAttribute. If AssemblyDelaySignAttribute has also been specified, it is likely that this file will only contain the public key.

An example of the syntax is [assembly:AssemblyKeyFileAttribute("myKey.snk")].

Caution noteCaution

Since the path and file name persist, ensure that the string you use with AssemblyKeyFileAttribute does not contain sensitive information.

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 Strong Name Tool (Sn.exe):

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++.

using namespace System;
using namespace System::Reflection;

[assembly:AssemblyKeyFileAttribute("TestPublicKey.snk")];
[assembly:AssemblyDelaySignAttribute(true)];

namespace DelaySign
{
    public ref class Test { };
}
