AddInToken.GetEnumerator Method

Definition

Namespace:

System.AddIn.Hosting

Assembly:

System.AddIn.dll

Returns an enumerator for the qualification data of the pipeline segments that are associated with this token.

public:
 virtual System::Collections::Generic::IEnumerator<System::AddIn::Hosting::QualificationDataItem> ^ GetEnumerator();

public System.Collections.Generic.IEnumerator<System.AddIn.Hosting.QualificationDataItem> GetEnumerator ();

abstract member GetEnumerator : unit -> System.Collections.Generic.IEnumerator<System.AddIn.Hosting.QualificationDataItem>
override this.GetEnumerator : unit -> System.Collections.Generic.IEnumerator<System.AddIn.Hosting.QualificationDataItem>

Public Function GetEnumerator () As IEnumerator(Of QualificationDataItem)

Returns

IEnumerator<QualificationDataItem>

An enumerator that can be used to iterate through the qualification data of the pipeline segments that are associated with the current token.

Implements

GetEnumerator()

Examples

The following example lists the qualification data for the pipeline segments associated with each AddInToken in a collection of tokens.

// 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}",
            token.Name,
            qdi.Segment,
            qdi.Name,
            qdi.Value);
    }
}

' Show the qualification data for each
' token in an AddInToken collection.
For Each token As AddInToken In tokens
    For Each qdi As QualificationDataItem In token
        Console.WriteLine("{0} {1}\n\t QD Name: {2}, QD Value: {3}", _
            token.Name, qdi.Segment, qdi.Name, qdi.Value)
    Next
Next

Remarks

Use this method to treat a token as if it were a collection of qualification data items, for example, in a foreach statement (For Each in Visual Basic, for each in Visual C++).

Use the enumerator returned by this method to iterate through the qualification data items of the pipeline segments associated with the current token. Each item of qualification data is a QualificationDataItem structure that identifies the pipeline segment and contains a name/value pair from a QualificationDataAttribute attribute applied to that segment.

Note

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 AddInSegmentType.HostViewOfAddIn.

Alternatively, you can use the QualificationData property to get a nested set of dictionaries that contain the qualification data of the pipeline segments.
