如何从excel复制特定的工作表名称并将其保存到新位置？使用 C#

Question

我正在使用 C# Windows 窗体。

目标：

如果我有多个 Excel 表格。

例如，"Sheet1, Sheet2, Sheet3, TestSheet1, TestSheet2"

如何获取特定的工作表名称，例如["Sheet2"] 并将其另存为新的 Excel 工作簿？

这是我目前所拥有的：

按钮点击：

private void button1_Click(object sender, EventArgs e)
{
    Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();
    Microsoft.Office.Interop.Excel.Workbook excelBook = excelApp.Workbooks.Open("C:\Users\LV98\Desktop\Test C#\excel_file.xlsx");

    excelBook.Worksheets.Copy("Sheet2");
}

更新：

这就是我要去的地方。

private void button1_Click(object sender, EventArgs e)
{
    Excel.Application excelApp;

    string fileTarget = "C:\\Users\\LV98\\Desktop\\Test C#\\template.xlsx";
    string fileTemplate = "C:\\Users\\LV98\\Desktop\\Test C#\\excel_file.xlsx";
    excelApp = new Excel.Application();
    Excel.Workbook wbTarget;
    Excel.Worksheet sh;

    //Create target workbook
    wbTarget = excelApp.Workbooks.Open(fileTemplate);

    //Fill target workbook
    //Open the template sheet
    sh = wbTarget.Worksheets["Sheet2"];
    sh.Copy(wbTarget.Worksheets[1]);


    //Save file
    wbTarget.SaveAs(fileTarget);
    wbTarget.Close(true);
    excelApp.Quit();

}

当我打开新的 excel 文件时，它会打开“Sheet2”，这正是我所追求的！但唯一的问题是，还保存了其他工作表。我将考虑重命名新工作表 - 并删除其余工作表。

只要在你的代码中试试这个就行了

foreach (Excel.Worksheet sheet in wbTarget.Worksheets)
            {
                //Save Particular sheet as file
                if (sheet.Name == "Sheet2")
                {
                    var newbook = excelApp.Workbooks.Add(1);
                    sheet.Copy(newbook.Sheets[1]);

                    newbook.SaveAs(@"C:\Users\LV98\Desktop\Test C#\" + sheet.Name);
                    newbook.Close();
                }
            }

您的按钮点击事件的完整代码。我测试了下面的代码，它工作正常

protected void button1_Click(object sender, EventArgs e)
    {
        Excel.Application excelApp;

        string fileTemplate = "C:\\Users\\LV98\\Desktop\\Test C#\\template.xlsx";            
        excelApp = new Excel.Application();
        Excel.Workbook wbTarget;

        //Create target workbook
        wbTarget = excelApp.Workbooks.Open(fileTemplate);

        foreach (Excel.Worksheet sheet in wbTarget.Worksheets)
        {
            //Save Particular sheet as file
            if (sheet.Name == "Sheet2")
            {
                var newbook = excelApp.Workbooks.Add(1);
                sheet.Copy(newbook.Sheets[1]);

                newbook.SaveAs(@"C:\Users\LV98\Desktop\Test C#\" + sheet.Name);
                newbook.Close();
            }
        }
        wbTarget.Close(true);
        excelApp.AskToUpdateLinks = false;
        excelApp.Quit();
        GetExcelProcess(excelApp);
    }
    [DllImport("user32.dll")]
    static extern int GetWindowThreadProcessId(int hWnd, out int lpdwProcessId);
    Process GetExcelProcess(Excel.Application excelApp)
    {
        int id;
        GetWindowThreadProcessId(excelApp.Hwnd, out id);
        return Process.GetProcessById(id);
    }

经过一番研究，我发现了一些有用的链接。 我在下面粘贴了一个代码 sn-p，我认为这会对您有所帮助：

IWorkbook sourceWorkbook = application.Workbooks.Open("Source.xlsx");
IWorkbook destinationWorkbook = application.Workbooks.Open("Destination.xlsx");

//Copy Excel worksheet from source workbook to the destination workbook
destinationWorkbook.Worksheets.AddCopy(sourceWorkbook.Worksheets[0]);

//Save the file
destinationWorkbook.Save();
