[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Specifies the variables that participate in a row.

Namespace:  Microsoft.SolverFoundation.Services
Assembly:  Microsoft.Solver.Foundation (in Microsoft.Solver.Foundation.dll)


Function GetActiveVariables ( _
    rowVid As Integer _
) As IEnumerable(Of Integer)
IEnumerable<int> GetActiveVariables(
    int rowVid
IEnumerable<int>^ GetActiveVariables(
    int rowVid
abstract GetActiveVariables : 
        rowVid:int -> IEnumerable<int> 
function GetActiveVariables(
    rowVid : int
) : IEnumerable<int>


Return Value

Type: System.Collections.Generic.IEnumerable<Int32>
An enumeration of active variables in rowVid.


Exception Condition

rowVid is not a valid row index.


In the case of a model that has explicit linear terms, that is, it implements ILinearModel, it is not necessary to specify the linear terms by using GetActiveVariables. If no call to SetActiveVariables has been made for the row, this method returns an empty result.
