Generische Methode für Excel.Workbook und Excel.Worksheet

Question

Ich schreibe ein Excel-Add-in und für 1 der Funktionen muss ich einige zusammenfassende Statistiken berechnen. Diese sollten als Namen entweder der gesamten Workbook oder einer einzelnen Worksheet hinzugefügt werden. Im Moment habe ich 2 Methoden, die jede Sache machen. Beide Methoden sehen jedoch fast identisch aus, mit dem Unterschied, dass der erste den Arbeitsbuch und der zweite den Arbeitsblatt hinzufügt.

Gibt es eine Möglichkeit, diese Methode generischer zu machen, so dass basierend auf den übergebenen Argumenten überprüft werden konnte, ob das bereitgestellte Arbeitsblatt null ist und wenn ja, zur gesamten Arbeitsmappe hinzufügen?

Answer 1

Anstatt zu versuchen, den Zugriff auf die Workbook und Worksheet generic würde ich sagen zu machen, dass ein Func<string, string, Name> Bereitstellung, die den Zugriff erlaubt zu rufen entweder die Workbook oder Worksheet wäre eine bessere Methode.

public DynamicSummaryStatistics(Range range, SummaryStatisticsBool doCalculate) 
{ 
    var functionToRun = (arg1, arg2) => Globals.ThisAddIn.Application.ActiveWorkbook.Names.Add(arg1, arg2); 

    this.ComputeDynamicSummaryStatistics(range, doCalculate, functionToRun); 
} 

public DynamicSummaryStatistics(Worksheet sheet, Range range, SummaryStatisticsBool doCalculate) 
{ 
    var functionToRun = (arg1, arg2) => sheet.Names.Add(arg1, arg2); 

    this.ComputeDynamicSummaryStatistics(range, doCalcualte, functionToRun); 
} 

private void ComputeDynamicSummaryStatistics(Range range, SummaryStatisticsBool doCalculate, Func<string, string, Name> functionToRun) 
{ 
    var name = ((Name)range.Name).Name; 
    if(doCalculate.Mean) Mean = functionToRun(name + "_MEAN", "=AVERAGE(" + name + ")"); 
    if(doCalculate.Variance) Variance = functionToRun(name + "_VAR", "=VAR.S(" + name + ")"); 
    // etc. etc. 
} 

So wird dieser Spruch in der Funktion ComputeDynamicSummaryStatistics jeden-Zeit, dass ich functionToRun ich entweder rufen sheet.Names.Add(...) oder Globals.ThisAddIn.Application.ActiveWorkbook.Names.Add(...) basierend auf nenne welchem ​​Konstruktor aufgerufen wurde.

Der Zugriff auf entweder die Workbook oder die Worksheet ist der Methode völlig unbekannt und alles, was es jetzt betrifft, ist die Angabe des Namens zum Hinzufügen.
