在Excel加载项（C＃）中以编程方式创建工作表

Question

According to MSDN, one can programmatically create and delete Excel Worksheets in Visual Studio ( http://msdn.microsoft.com/en-us/library/6fczc37s.aspx ). The code to do so is as follows:

private void createNewAccount()
{            
    Excel.Worksheet newWorksheet;
    newWorksheet = Globals.ThisAddIn.Application.ThisWorkbook.Worksheets.Add();            
}

One of the forms in my project has a button carrying this code. The user is supposed to be able to press it and create a new worksheet, but it doesn't work. So I decided to make it a button on a ribbon tab, instead. That didn't work either. What am I missing?

My answer is not going to be too long.

If you need to go Microsoft way, please first be sure to first create a Book. Remember Excel files resemble a workbook , then, inside, you can create worksheets.

If you don't please take a look at NPOI project .

With both approaches you will have to create the workbook, then the worksheets inside.

Well, If you are sure you have access to a WorkBook I would recommend you to:

1.- Use the parameters of the WorkSheets.Add method

2.- Please take a look at this example .

3.- Persist the workbook after the worksheet is added. This will allow to check if it was added or not.

Last but not least, debug, debug and debug.

Hope that helps,
