Represents one reference in the project. Including a reference in a project allows you to use any of the public members contained in the reference. Projects may include references to other .NET projects, .NET assemblies, and COM objects.

Examples

The following example creates a new project from a template, adds two references, and displays their types.

'Macro Editor  
Imports VSLangProj  
Sub NewProject()  
   Dim newName As String = InputBox("New project name:")  
   ' Create a new project in the solution based on an existing  
   ' project.  
   Dim newProject As Project = DTE.Solution.AddFromTemplate( _  
      "C:\TemplatePath\Template.vbproj", _  
      "C:\ProjectPath\" & newName, newName)  

   ' Add a COM reference and display its type.  
   Dim vsProject As VSProject = CType(newProject.Object, VSProject)  
   Dim newRef As Reference  
   newRef = vsProject.References.Add("C:\WINNT\System32\msmask32.ocx")  
   MsgBox(GetRefTypeName(newRef))  

   ' Add an Assembly reference and display its type, "Assembly".  
   newRef = vsProject.References.Add("C:\SomeProject\bin\SomeProject.dll")  
   MsgBox(GetRefTypeName(newRef))  
End Sub  

Private Function GetRefTypeName(ByVal ref As Reference) _  
   As String  
   Dim type As String  
   Select Case ref.Type  
      Case prjReferenceType.prjReferenceTypeActiveX  
         type = "COM"  
      Case prjReferenceType.prjReferenceTypeAssembly  
         type = "Assembly"  
   End Select  
   Return type  
End Function

The following example creates a short report of a reference's properties.

' Macro Editor  
' Create a small report about a reference.  
Imports VSLangProj  
Function ReportReferences(ByVal aRef As Reference) As String  
   Dim report As String = ""  
   Dim type As String  
   ' Each entry in the ArrayList will contain a label and a value.  
   Dim ht As System.Collections.ArrayList = _  
      New System.Collections.ArrayList()  
   With aRef  
      ht.Add(New String() {"Name", .Name})  
      ht.Add(New String() {"Description", .Description})  
      ht.Add(New String() {"Version", String.Format("{0}.{1}.{2}.{3}", _  
         .MajorVersion, .MinorVersion, .BuildNumber, .RevisionNumber)})  
      ht.Add(New String() {"Location", .ContainingProject.FullName})  
      Select Case .Type  
         Case prjReferenceType.prjReferenceTypeActiveX  
            type = "COM"  
         Case prjReferenceType.prjReferenceTypeAssembly  
            type = "Assembly"  
      End Select  
      ht.Add(New String() {"Type", type})  
      ht.Add(New String() {"Culture", .Culture})  
   End With  

   Dim datas() As String  
   For Each datas In ht  
      report &= datas(0) & ControlChars.Tab & datas(1) & ControlChars.CrLf  
   Next  
   Return report  
End Function

Remarks

Reference objects are contained in the VSProject object's References collection. There are two types of Reference objects: assemblies (including Visual Studio projects) and COM objects. When a reference is another project, this is called a project-to-project reference and is still considered an assembly reference.

Properties

BuildNumber	Gets the build number of the reference. Read-only.
Collection	Gets the collection containing the object supporting this property or contained within this code construct.
ContainingProject	Gets the project that the selected item is a part of. Read-only.
CopyLocal	Determines whether the reference is copied to the local bin path.
Culture	Gets the culture string of a reference. Read-only.
Description	Gets a text description of the reference. Read-only.
DTE	Gets the top-level extensibility object.
Extender[String]	Gets the requested Extender object if it is available for this object.
ExtenderCATID	Gets the Extender category ID (CATID) for the object.
ExtenderNames	Gets a list of available Extenders for the object.
Identity	Gets the unique identifier of the reference. Read-only.
MajorVersion	Gets the major version number of the reference. Read-only.
MinorVersion	Gets the minor version number of the reference. Read-only.
Name	Gets the name of the object. Read-only.
Path	Gets the path to the reference file. Read-only.
PublicKeyToken	Gets the public key token for the referenced assembly.
RevisionNumber	Gets the revision number of the reference. Read-only.
SourceProject	Gets a Project object if the reference is a project. Otherwise, it returns Nothing (a null reference). Read-only.
StrongName	Gets whether the reference is signed with a public/private key pair. Read-only.
Type	Gets a prjReferenceType value indicating whether the reference is an assembly or a COM component. Read-only.
Version	Gets the version of the selected reference.

Methods

Remove()

Gets the reference from the References object that contains it.
