Type Library Importer (Tlbimp.exe)

Статья
12/05/2006

The Type Library Importer converts the type definitions found within a COM type library into equivalent definitions in a common language runtime assembly. The output of Tlbimp.exe is a binary file (an assembly) that contains runtime metadata for the types defined within the original type library. You can examine this file with tools such as Ildasm.exe.

tlbimp tlbFile [options]

Parameters

Argument	Description
tlbFile	The name of any file that contains a COM type library.

Option	Description
/asmversion:versionNumber	Specifies the version number of the assembly to produce. Specify versionNumber in the format major.minor.build.revision.
/delaysign	Specifies to Tlbimp.exe to sign the resulting assembly with a strong name using delayed signing. You must specify this option with either the /keycontainer:, /keyfile:, or /publickey: option. For more information on the delayed signing process, see Delay Signing an Assembly.
/help	Displays command syntax and options for the tool.
/keycontainer:containername	Signs the resulting assembly with a strong name using the public/private key pair found in the key container specified by containername.
/keyfile:filename	Signs the resulting assembly with a strong name using the publisher's official public/private key pair found in filename.
/namespace:namespace	Specifies the namespace in which to produce the assembly.
/noclassmembers	Prevents Tlbimp.exe from adding members to classes. This avoids a potential TypeLoadException.
/nologo	Suppresses the Microsoft startup banner display.
/out:filename	Specifies the name of the output file, assembly, and namespace in which to write the metadata definitions. The /out option has no effect on the assembly's namespace if the type library specifies the Interface Definition Language (IDL) custom attribute that explicitly controls the assembly's namespace. If you do not specify this option, Tlbimp.exe writes the metadata to a file with the same name as the actual type library defined within the input file and assigns it a .dll extension. If the output file is the same name as the input file, the tool generates an error to prevent overwriting the type library.
/primary	Produces a primary interop assembly for the specified type library. Information is added to the assembly indicating that the publisher of the type library produced the assembly. By specifying a primary interop assembly, you differentiate a publisher's assembly from any other assemblies that are created from the type library using Tlbimp.exe. You should only use the /primary option if you are the publisher of the type library that you are importing with Tlbimp.exe. Note that you must sign a primary interop assembly with a strong name. For more information, see Primary Interop Assemblies.
/publickey:filename	Specifies the file containing the public key to use to sign the resulting assembly. If you specify the /keyfile: or /keycontainer: option instead of /publickey:, Tlbimp.exe generates the public key from the public/private key pair supplied with /keyfile: or /keycontainer:. The /publickey: option supports test key and delay signing scenarios. The file is in the format generated by Sn.exe. For more information, see the -p option of Sn.exe in Strong Name Tool (Sn.exe).
/reference:filename	Specifies the assembly file to use to resolve references to types defined outside the current type library. If you do not specify the /reference option, Tlbimp.exe automatically recursively imports any external type library that the type library being imported references. If you specify the /reference option, the tool attempts to resolve external types in the referenced assemblies before it imports other type libraries.
/silent	Suppresses the display of success messages.
/strictref	Does not import a type library if the tool cannot resolve all references within the current assembly, the assemblies specified with the /reference option, or registered primary interop assemblies (PIAs).
/strictref:nopia	Same as /strictref, but ignores PIAs.
/sysarray	Specifies to the tool to import a COM style SafeArray as a managed System.Array Class type.
/tlbreference:filename	Specifies the type library file to use to resolve type library references without consulting the registry. Note that this option will not load some older type library formats. However, you can still load older type library formats implicitly through the registry or current directory.
/transform:transformName	Transforms metadata as specified by the transformName parameter. Specify dispret for the transformName parameter to transform [out, retval] parameters of methods on dispatch-only interfaces (dispinterfaces) into return values. For more information about this option, see the examples later in this topic.
/unsafe	Produces interfaces without .NET Framework security checks. Calling a method that is exposed in this way might pose a security risk. You should not use this option unless you are aware of the risks of exposing such code.
/verbose	Specifies verbose mode; displays additional information about the imported type library.
/?	Displays command syntax and options for the tool.

Note

The command-line options for Tlbimp.exe are case-insensitive and can be supplied in any order. You only need to specify enough of the option to uniquely identify it. Therefore, /n is equivalent to /nologo and /ou:outfile.dll is equivalent to /out:outfile.dll.

Remarks

Tlbimp.exe performs conversions on an entire type library at one time. You cannot use the tool to generate type information for a subset of the types defined within a single type library.

It is often useful or necessary to be able to assign strong names to assemblies. Therefore, Tlbimp.exe includes options for supplying the information necessary to generate strongly named assemblies. Both the /keyfile: and /keycontainer: options sign assemblies with strong names. Therefore, it is logical to supply only one of these options at a time.

A resource ID can optionally be appended to a type library file when importing a type library from a module containing multiple type libraries. Tlbimp.exe is able to locate this file only if it is in the current directory or if you specify the full path. See the example later in this topic.

Examples

The following command generates an assembly with the same name as the type library found in myTest.tlb and with the .dll extension.

tlbimp myTest.tlb

The following command generates an assembly with the name myTest.dll.

tlbimp  myTest.tlb  /out:myTest.dll

The following command generates an assembly with the same name as the type library specified by MyModule.dll\1 and with the .dll extension. MyModule.dll\1 must be located in the current directory.

tlbimp MyModule.dll\1

The following command generates an assembly with the name myTestLib.dll for the type library TestLib.dll. The /transform:dispret option transforms any [out, retval] parameters of methods on dispinterfaces in the type library into return values in the managed library.

tlbimp TestLib.dll /transform:dispret /out:myTestLib.dll

The type library TestLib.dll, in the preceding example, includes a dispinterface method named SomeMethod that returns void and has an [out, retval] parameter. The following code is the input type library method signature for SomeMethod in TestLib.dll.

void SomeMethod([out, retval] VARIANT_BOOL*);

Specifying the /transform:dispret option causes Tlbimp.exe to transform the [out, retval] parameter of SomeMethod into a bool return value. The following is the method signature that Tlbimp.exe produces for SomeMethod in the managed library myTestLib.dll when the /transform:dispret option is specified.

bool SomeMethod();

If you use Tlbimp.exe to produce a managed library for TestLib.dll without specifying the /transform:dispret, the tool produces the following method signature for SomeMethod in the managed library myTestLib.dll.

void SomeMethod(out bool x);
