ConvertTypeLibToAssembly(Object, String, Int32, ITypeLibImporterNotifySink, Byte[], StrongNameKeyPair, Boolean)

Converts a COM type library to an assembly.

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);

public System.Reflection.Emit.AssemblyBuilder ConvertTypeLibToAssembly (object typeLib, string asmFileName, int flags, System.Runtime.InteropServices.ITypeLibImporterNotifySink notifySink, 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

AssemblyBuilder

An AssemblyBuilder object containing the converted type library.

Implements

ConvertTypeLibToAssembly(Object, String, Int32, ITypeLibImporterNotifySink, Byte[], StrongNameKeyPair, Boolean)

Exceptions

ArgumentNullException

typeLib is null.

-or-

asmFileName is null.

-or-

notifySink is null.

ArgumentException

asmFileName is an empty string.

-or-

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

InvalidOperationException

flags is not PrimaryInteropAssembly.

-or-

publicKey and keyPair are null.

ReflectionTypeLoadException

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.
