在C#中重命名Excel工作表名称

Question

VS 2008/C#.

在传递电子表格的文件路径时,我需要重命名工作表.

如何将Excel工作表的Sheet1重命名为"ABC".

我们将Excel工作表导出到SQL数据库.Excel工作表中的记录由最终用户手动编辑和更新.列值可以具有不同的数据类型.

默认情况下,电子表格将有三张表格作为Sheet1,Sheet2,Sheet3.

最终用户,通常在Sheet1上工作.我们需要为这个Sheet1维护一个静态名称,这有助于我们将Sheet1导出到SQL数据库.

如果我们将Sheet1重命名为ABC,我们将保持相同的名称.我们不能像那样导出默认表.因为,最终用户可能会更改其名称或坚持使用默认名称.

为了避免混淆,我们决定重命名Spread Sheet的Sheet1.

Answer 1

C#3.0

using Microsoft.Office.Interop.Excel;

然后

object oMissing = System.Reflection.Missing.Value;

Microsoft.Office.Interop.Excel.ApplicationClass xl = new Microsoft.Office.Interop.Excel.ApplicationClass();

Microsoft.Office.Interop.Excel.Workbook xlBook;
Microsoft.Office.Interop.Excel.Worksheet xlSheet;

string laPath = System.IO.Path.GetFullPath("C:\\ExcelSheet.xls");
xlBook = (Workbook)xl.Workbooks.Open(laPath, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing);

xlSheet = (Worksheet)xlBook.Worksheets.get_Item(1);
xlSheet.Name = "CIAO";
xlBook.Save();
xl.Application.Workbooks.Close();

C#4.0+

区别在于:不再System.Reflection.Missing.Value使用DLR(动态语言运行时)

using System.IO;

using Excel = Microsoft.Office.Interop.Excel;
using Word = Microsoft.Office.Interop.Word;

然后

var excelFile = Path.GetFullPath("C:\\ExcelSheet.xls");
var excel = new Excel.Application();
var workbook = excel.Workbooks.Open(excelFile);
var sheet = (Excel.Worksheet)workbook.Worksheets.Item[1]; // 1 is the first item, this is NOT a zero-based collection
sheet.Name = DateTime.Now.ToString("yyyyMMddHHmmss");
workbook.Save();
excel.Application.Workbooks.Close();
