C＃默认创建Excel工作簿1张

问题描述：

我正在尝试使用C＃COM互操作来创建一个Excel文件，但是默认情况下它会创建3个文件，而不是空白或仅一个。
需要创建它为空或只是一个：

I'm trying to create an Excel file with C# COM interop but seems it create it by default with 3 sheets instead of empty or only one. What is needed to create it Empty or just with one:

Excel.Application xl = null;
Excel._Workbook wb = null;

// Create a new instance of Excel from scratch
xl = new Excel.Application();
xl.Visible = true;     
wb = (Excel._Workbook)(xl.Workbooks.Add(Missing.Value));

wb.SaveAs(@"C:\a.xls", Excel.XlFileFormat.xlWorkbookNormal,
 null, null, false, false, Excel.XlSaveAsAccessMode.xlShared,
 false, false, null, null, null);

答

看看MSDN对 Workbooks.Add方法。

尝试 Workbooks.Add（XlWBATemplate.xlWBATWorksheet）或

查看是否可以将 xl.SheetsInNewWorkbook 属性设置为0或1。

Try Workbooks.Add(XlWBATemplate.xlWBATWorksheet), or
See if you can set the xl.SheetsInNewWorkbook property to 0 or 1.

$ b $我进行了验证。这是代码：

I went ahead and verified this. Here is the code:

using Microsoft.Office.Interop.Excel;
using System.Reflection;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Application xl = null;
            _Workbook wb = null;

            // Option 1
            xl = new Application();
            xl.Visible = true;
            wb = (_Workbook)(xl.Workbooks.Add(XlWBATemplate.xlWBATWorksheet));

            // Option 2
            xl = new Application();
            xl.SheetsInNewWorkbook = 1;
            xl.Visible = true;
            wb = (_Workbook)(xl.Workbooks.Add(Missing.Value));

        }
    }
}
