Examples

The following example adds two references to an open Visual Basic or Visual C# project. It then calls a function, GetRefTypeName, to display the reference type and calls a function, ReportReferences, to display additional reference properties. To run this example as an add-in, see How to: Compile and Run the Automation Object Model Code Examples.

The default paths for the added references are : <installation root>\Program Files\Microsoft.NET\Primary Interop Assemblies for adodb.dll, and <installation root>\Program Files\Common Files\SpeechEngines\Microsoft for spcommon.dll. Replace the <file path> in the example with these or other appropriate file paths.

Remarks

Reference3 defines the following new parameters:

Aliases

AutoReferenced

Isolated

RefType

SpecificVersion

Properties

Aliases	Gets or sets the aliased names for the specified reference. This property applies to Visual C# only.
AutoReferenced	Gets whether the reference is automatically referenced by the compiler.
BuildNumber	Gets the build number of the reference.
Collection	Gets a collection of References.
ContainingProject	Gets the Project containing the reference.
CopyLocal	Gets or sets whether the reference is copied to the local bin path.
Culture	Gets the culture string of a reference.
Description	Gets a text description of the reference.
DTE	Gets the top-level extensibility object.
ExtenderCATID	Microsoft Internal Use Only.
ExtenderNames	Microsoft Internal Use Only.
Identity	Gets the unique identifier of the reference.

Name	Gets the name of the object.
Path	Gets the path to the reference file.

RefType	Gets the type of reference: assembly, COM, or native.
Resolved	Gets whether the current reference was resolved.
RevisionNumber	Gets the revision number of the reference.
RuntimeVersion	Gets the version of the runtime against which the reference was built. This is applicable only for .NET references.
SourceProject	Gets a Project object if the reference is a project. Otherwise, it returns Nothing (a null object).
SpecificVersion	Gets or sets whether only a specific version of the reference is used.
StrongName	Gets whether the reference is signed with a public/private key pair.
SubType	Sets or Gets the assembly subtype.
Type	Obsolete. Included for backward compatibility only. Use RefType instead.
Version	Gets the version of the specified reference.

Methods

get_Extender(String)
Remove()	Removes the reference from the References object that contains it.
