C#默认情况下,使用1张创建Excel工作簿

Question

我正在尝试使用C#COM互操作创建一个Excel文件,但它似乎默认创建了3张而不是空或只有一张.创建它需要什么空或只需一个:

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);

Answer 1

看看MSDN对Workbooks.Add方法的解释.

1. 试试Workbooks.Add(XlWBATemplate.xlWBATWorksheet),或
2. 查看是否可以将xl.SheetsInNewWorkbook属性设置为0或1.

我继续进行验证.这是代码:

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));

        }
    }
}
