C＃上的TimeScaleData

Question

我正在将宏代码迁移到VSTO中。我遇到TimeScaleData问题。宏代码是这样的。

For Each tsk In ActiveProject.Tasks
    If tsk.Summary = False And tsk.Duration <> 0 Then
        With tsk 
            Set tsvs = .TimeScaleData(StartDate:=ActiveProject.ProjectStart, EndDate:=ActiveProject.ProjectFinish, Type:=pjTaskTimescaledBaselineWork, timescaleunit:=pjTimescaleWeeks, Count:=1)
        End With
        For Each tsv In tsvs 
           differencedate = 0
           If tsk.BaselineStart <> "NA" And tsk.BaselineFinish <> "NA" Then

                If tsk.BaselineStart >= tsv.StartDate And tsk.BaselineStart <= tsv.StartDate + 7 And tsk.BaselineFinish <= tsv.StartDate + 7 Then
                    differencedate = Application.DateDifference(tsk.BaselineStart, tsk.BaselineFinish, ActiveProject.Calendar) / 60

                ElseIf tsk.BaselineStart >= tsv.StartDate And tsk.BaselineStart <= tsv.StartDate + 7 And tsk.BaselineFinish >= tsv.StartDate + 7 Then
                     differencedate = (Application.DateDifference(tsk.BaselineStart, tsv.StartDate + 7, ActiveProject.Calendar)) / 60


                ElseIf tsk.BaselineStart <= tsv.StartDate And tsk.BaselineFinish >= tsv.StartDate And tsk.BaselineFinish <= tsv.StartDate + 7 Then
                     differencedate = (Application.DateDifference(tsv.StartDate, tsk.BaselineFinish, ActiveProject.Calendar)) / 60

                ElseIf tsk.BaselineStart <= tsv.StartDate And tsk.BaselineFinish >= tsv.StartDate + 7 Then
                     differencedate = Application.DateDifference(tsv.StartDate, tsv.StartDate + 7, ActiveProject.Calendar) / 60

                End If
          End If
    Next
    End if
Next

我需要将此翻译为C＃，任何可以提供帮助的人吗？
