public:
 virtual System::Reflection::Emit::AssemblyBuilder ^ ConvertTypeLibToAssembly(System::Object ^ typeLib, System::String ^ asmFileName, int flags, System::Runtime::InteropServices::ITypeLibImporterNotifySink ^ notifySink, cli::array <System::Byte> ^ publicKey, System::Reflection::StrongNameKeyPair ^ keyPair, bool unsafeInterfaces);

abstract member ConvertTypeLibToAssembly : obj * string * int * System.Runtime.InteropServices.ITypeLibImporterNotifySink * byte[] * System.Reflection.StrongNameKeyPair * bool -> System.Reflection.Emit.AssemblyBuilder
override this.ConvertTypeLibToAssembly : obj * string * int * System.Runtime.InteropServices.ITypeLibImporterNotifySink * byte[] * System.Reflection.StrongNameKeyPair * bool -> System.Reflection.Emit.AssemblyBuilder
Public Function ConvertTypeLibToAssembly (typeLib As Object, asmFileName As String, flags As Integer, notifySink As ITypeLibImporterNotifySink, publicKey As Byte(), keyPair As StrongNameKeyPair, unsafeInterfaces As Boolean) As AssemblyBuilder

Parameters

typeLib
Object

The object that implements the ITypeLib interface.

asmFileName
String

The file name of the resulting assembly.

flags
Int32

A TypeLibImporterFlags value indicating any special settings.

notifySink
ITypeLibImporterNotifySink

ITypeLibImporterNotifySink interface implemented by the caller.

publicKey
Byte[]

A byte array containing the public key.

keyPair
StrongNameKeyPair

A StrongNameKeyPair object containing the public and private cryptographic key pair.

unsafeInterfaces
Boolean

If true, the interfaces require link time checks for UnmanagedCode permission. If false, the interfaces require run time checks that require a stack walk and are more expensive, but help provide greater protection.

Returns

An AssemblyBuilder object containing the converted type library.

Implements

Exceptions

typeLib is null.

-or-

asmFileName is null.

-or-

notifySink is null.

asmFileName is an empty string.

-or-

asmFileName is longer than the system-defined maximum length. For more information, see PathTooLongException.

flags is not PrimaryInteropAssembly.

-or-

publicKey and keyPair are null.

The metadata produced has errors preventing any types from loading.

Remarks

If you do not want to generate a strong name for your assembly, it is valid for publicKey and keyPair to be null, as long as flags does not equal TypeLibImporterFlags.PrimaryInteropAssembly. Otherwise, at least one of these parameters must be specified. If publicKey is null, the public key in keyPair will be set in the target assembly's manifest metadata and a signature will be generated based on the contents of the assembly. If keyPair is null, publicKey will be set in the target assembly's manifest metadata and no signature will be generated. Specifying both parameters is not generally useful, and can result in an invalid signature.

For more information on ITypeLib, please see its existing documentation in the MSDN library.
