QualificationDataItem.Segment Property


Gets a value that identifies the pipeline segment the qualification data item was applied to.

Namespace:   System.AddIn.Hosting
Assembly:  System.AddIn (in System.AddIn.dll)

public AddInSegmentType Segment { get; }

Property Value

Type: System.AddIn.Hosting.AddInSegmentType

The kind of pipeline segment the data item was applied to.

When you enumerate qualification data, use this property to identify the qualification data that belongs to a particular segment of the pipeline.


The add-in model does not use qualification data that is applied to the host view of the add-in. As a result, when you enumerate qualification data you will not find any items whose Segment property is HostViewOfAddIn.

The following example lists the qualification data for the pipeline segments associated with each AddInToken in a collection of tokens. The Segment property is used to display the kind of segment.

// Show the qualification data for each
// token in an AddInToken collection.
foreach (AddInToken token in tokens)
    foreach (QualificationDataItem qdi in token)
        Console.WriteLine("{0} {1}\n\t QD Name: {2}, QD Value: {3}",
