Probleme mit finden und ersetzen Excel C#

Question

Hey ich habe Probleme mit meinem Code, die nicht wirklich arbeiten möchten, hat mit Word-Interop funktioniert, aber wenn ich es in Excel ändern, bringt es mir eine Fehlermeldung in Private void CreateWordDocument (Excel .document Adoc und excelapp.document.open)

private void FindAndReplace(Microsoft.Office.Interop.Excel.Application wordApp, object findText, object replaceWithText) 
    { 
     object matchCase = true; 
     object matchWholeWord = true; 
     object matchWildCards = false; 
     object matchSoundLike = false; 
     object nmatchAllForms = false; 
     object forward = true; 
     object format = false; 
     object matchKashida = false; 
     object matchDiactitics = false; 
     object matchAlefHamza = false; 
     object matchControl = false; 
     object read_only = false; 
     object visible = true; 
     object replace = 2; 
     object wrap = 1; 

     wordApp.Selection.Find.Execute(ref findText, 
        ref matchCase, ref matchWholeWord, 
        ref matchWildCards, ref matchSoundLike, 
        ref nmatchAllForms, ref forward, 
        ref wrap, ref format, ref replaceWithText, 
        ref replace, ref matchKashida, 
        ref matchDiactitics, ref matchAlefHamza, 
        ref matchControl); 
    } 



    string pathImage = null; 
    private void CreateWordDocument(object filename, object savaAs, object image) 
    { 
     List<int> processesbeforegen = getRunningProcesses(); 
     object missing = Missing.Value; 


     Excel.Application excelApp = new Excel.Application(); 

     Excel.Document aDoc = null; 

     if (File.Exists((string)filename)) 
     { 
      DateTime today = DateTime.Now; 

      object readOnly = false; //default 
      object isVisible = false; 

      excelApp.Visible = false; 

      aDoc = excelApp.Document.Open(ref filename, ref missing, ref readOnly, 
             ref missing, ref missing, ref missing,

      aDoc.Activate(); 

      //Find and replace: 
      this.FindAndReplace(excelApp, "$$firstname$$", txtFirstName.Text);

     else

    //Load the Template Document:

      tFilename.Text = openFileDialog1.FileName;

     } 
    } 
} 

}

Wort Interop und Excel Interop sind sehr unterschiedlich. Sie können "Word" nicht einfach in "Excel" ändern. Sie werden wahrscheinlich das Arbeitsblatt auswählen, einen Bereich von Zellen definieren, den Bereich durchlaufen müssen usw. Viele Snippets bei Google.
