Examples

The following example finds a specific add-in.

// Find a specific add-in.

// Construct the path to the add-in.
string addInFilePath = pipeRoot + @"\AddIns\P3AddIn2\P3AddIn2.dll";

// The fourth parameter, addinTypeName, takes the full name
// of the type qualified by its namespace. Same as AddInToken.AddInFullName.
Collection<AddInToken> tokenColl = AddInStore.FindAddIn(typeof(Calculator),
    pipeRoot, addInFilePath, "CalcAddIns.P3AddIn2");
Console.WriteLine("Found {0}", tokenColl[0].Name);
' Find a specific add-in.
' Construct the path to the add-in.
Dim addInFilePath As String = (pipeRoot + "\AddIns\P3AddIn2\P3AddIn2.dll")
' The fourth parameter, addinTypeName, takes the full name 
' of the type qualified by its namespace. Same as AddInToken.AddInFullName.
Dim tokenColl As System.Collections.ObjectModel.Collection(Of AddInToken) = AddInStore.FindAddIn(GetType(Calculator), pipeRoot, addInFilePath, "CalcAddIns.P3AddIn2")
Console.WriteLine("Found {0}", tokenColl(0).Name)

Remarks

If a single pipeline for an add-in is found, it will be the only item in the AddInToken collection. If multiple pipelines to the specified add-in are found, you can differentiate them by examining the QualificationData property.
