Excel Interop - 在所有其他人之后添加一个新的工作表

问题描述

我正在尝试向Excel工作簿添加一个新的工作表，并将其作为C＃Excel Interop中的最后一个工作表。

看起来很简单，我以为下面的代码会这样做：

  c> c 添加和之后的参数传递给我的最后一个工作表的名称。 code>移动方法，没有快乐！
 
 
 
这是我试过的，所以我的问题是如何添加工作表到Excel工作簿，并将其作为工作簿中的最后一张表使用C＃Excel Interop？
 
 
 
谢谢
解决方案
在这里查看文档，它表示after对象不是数字位置;表示您要将您的工作表定位的工作表的对象。代码应该是（未经测试的）：
  workbook.Sheets.Add（After：workbook.Sheets [workbook.Sheets 。计数]）; 
  
 
I am trying to add a new worksheet to an Excel workbook and make this the last worksheet in the book in C# Excel Interop.
It seems really simple, and I thought the below code would do it:
using System.Runtime.InteropServices;
using Excel = Microsoft.Office.Interop.Excel;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            var excel = new Excel.Application();

            var workbook = excel.Workbooks.Open(@"C:\test\Test.xlsx");
            workbook.Sheets.Add(After: workbook.Sheets.Count);

            workbook.Save();
            workbook.Close();

            Marshal.ReleaseComObject(excel);
        }
    }
}
No such luck. I get this helpful error:
I found this page on Microsoft.com which suggested I try and add the sheet first and then move it so I tried that as shown below. I know that this webpage targets Excel 95 but the VBA is still there to use so I was hoping it would still work:
using System.Runtime.InteropServices;
using Excel = Microsoft.Office.Interop.Excel;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            var excel = new Excel.Application();

            var workbook = excel.Workbooks.Open(@"C:\test\Test.xlsx");
            workbook.Sheets.Add();
            workbook.Sheets.Move(After: workbook.Sheets.Count);

            workbook.Save();
            workbook.Close();

            Marshal.ReleaseComObject(excel);
        }
    }
}
I get the same error as above. I have also tried passing the name of my last worksheet as a string as the After parameter in both the Add and Move methods, no joy!
That is what I have tried, so my question is how do I add a worksheet to an Excel workbook and make this the last sheet in the workbook using C# Excel Interop?
Thanks

Looking at the documentation here http://msdn.microsoft.com/en-us/library/microsoft.office.tools.excel.worksheet.move(v=vs.80).aspx, it indicates that the 'after' object isn't a numerical position; it's the object representing the sheet you want to position your sheet after. The code should probably be something like (untested):
workbook.Sheets.Add(After: workbook.Sheets[workbook.Sheets.Count]);
