C# 我想从c创建xlsx（Excel）文件#

这是一个只能创建xls文件的代码。但是我想创建xlsx（Excel）文件；我如何从这段代码中做到这一点，或者我可以使用另一段代码来创建xlsx文件

using Excel = Microsoft.Office.Interop.Excel;
using System.Runtime.InteropServices;


Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();

            if (xlApp == null)
            {
                MessageBox.Show("Excel is not properly installed!!");
                return;
            }


            Excel.Workbook xlWorkBook;
            Excel.Worksheet xlWorkSheet;
            object misValue = System.Reflection.Missing.Value;

            xlWorkBook = xlApp.Workbooks.Add(misValue);
            xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

            xlWorkSheet.Cells[1, 1] = "ID";
            xlWorkSheet.Cells[1, 2] = "Name";
            xlWorkSheet.Cells[2, 1] = "1";
            xlWorkSheet.Cells[2, 2] = "One";
            xlWorkSheet.Cells[3, 1] = "2";
            xlWorkSheet.Cells[3, 2] = "Two";



            xlWorkBook.SaveAs("d:\\vdfgdfg.xls", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
            xlWorkBook.Close(true, misValue, misValue);
            xlApp.Quit();

            Marshal.ReleaseComObject(xlWorkSheet);
            Marshal.ReleaseComObject(xlWorkBook);
            Marshal.ReleaseComObject(xlApp);

            MessageBox.Show("Excel file created , you can find the file d:\\csharp-Excel.xls");
        }

    ExcelDocument workbook = new ExcelDocument(1);

    // Set the sheet name
    workbook.easy_getSheetAt(0).setSheetName("Sheet1");

   // Add data
   ExcelTable xlsTable = ((ExcelWorksheet)workbook.easy_getSheetAt(0)).easy_getExcelTable();
   xlsTable.easy_getCell(0, 0).setValue("ID");
   xlsTable.easy_getCell(0, 1).setValue("Name");
   xlsTable.easy_getCell(1, 0).setValue("1");
   xlsTable.easy_getCell(1, 1).setValue("One");
   xlsTable.easy_getCell(2, 0).setValue("2");
   xlsTable.easy_getCell(2, 1).setValue("Two");

    // Create Excel file
    workbook.easy_WriteXLSXFile("d:\\vdfgdfg.xlsx");

请尝试下面更新的代码

    public void CreateExcel()
    {
      Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();

        if (xlApp == null)
        {
            MessageBox.Show("Excel is not properly installed!!");
            return;
        }


        Microsoft.Office.Interop.Excel.Workbook xlWorkBook;
        Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet;
        object misValue = System.Reflection.Missing.Value;

        xlWorkBook = xlApp.Workbooks.Add(misValue);
        xlWorkSheet = (Microsoft.Office.Interop.Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

        xlWorkSheet.Cells[1, 1] = "ID";
        xlWorkSheet.Cells[1, 2] = "Name";
        xlWorkSheet.Cells[2, 1] = "1";
        xlWorkSheet.Cells[2, 2] = "One";
        xlWorkSheet.Cells[3, 1] = "2";
        xlWorkSheet.Cells[3, 2] = "Two";

                  //Here saving the file in xlsx
                xlWorkBook.SaveAs("d:\\vdfgdfg.xlsx", Microsoft.Office.Interop.Excel.XlFileFormat.xlOpenXMLWorkbook, misValue,
                misValue, misValue, misValue, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);


        xlWorkBook.Close(true, misValue, misValue);
        xlApp.Quit();

        Marshal.ReleaseComObject(xlWorkSheet);
        Marshal.ReleaseComObject(xlWorkBook);
        Marshal.ReleaseComObject(xlApp);

        MessageBox.Show("Excel file created , you can find the file d:\\csharp-Excel.xlsx");
    }

看一看。它是一个创建xlsx文件的库

using Excel = Microsoft.Office.Interop.Excel;
using System.Runtime.InteropServices;


Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();

            if (xlApp == null)
            {
                MessageBox.Show("Excel is not properly installed!!");
                return;
            }


            Excel.Workbook xlWorkBook;
            Excel.Worksheet xlWorkSheet;
            object misValue = System.Reflection.Missing.Value;

            xlWorkBook = xlApp.Workbooks.Add(misValue);
            xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

            xlWorkSheet.Cells[1, 1] = "ID";
            xlWorkSheet.Cells[1, 2] = "Name";
            xlWorkSheet.Cells[2, 1] = "1";
            xlWorkSheet.Cells[2, 2] = "One";
            xlWorkSheet.Cells[3, 1] = "2";
            xlWorkSheet.Cells[3, 2] = "Two";



            xlWorkBook.SaveAs("d:\\vdfgdfg.xls", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
            xlWorkBook.Close(true, misValue, misValue);
            xlApp.Quit();

            Marshal.ReleaseComObject(xlWorkSheet);
            Marshal.ReleaseComObject(xlWorkBook);
            Marshal.ReleaseComObject(xlApp);

            MessageBox.Show("Excel file created , you can find the file d:\\csharp-Excel.xls");
        }

    ExcelDocument workbook = new ExcelDocument(1);

    // Set the sheet name
    workbook.easy_getSheetAt(0).setSheetName("Sheet1");

   // Add data
   ExcelTable xlsTable = ((ExcelWorksheet)workbook.easy_getSheetAt(0)).easy_getExcelTable();
   xlsTable.easy_getCell(0, 0).setValue("ID");
   xlsTable.easy_getCell(0, 1).setValue("Name");
   xlsTable.easy_getCell(1, 0).setValue("1");
   xlsTable.easy_getCell(1, 1).setValue("One");
   xlsTable.easy_getCell(2, 0).setValue("2");
   xlsTable.easy_getCell(2, 1).setValue("Two");

    // Create Excel file
    workbook.easy_WriteXLSXFile("d:\\vdfgdfg.xlsx");

尝试OpenXML库，应该可以做到这一点，在

请注意，除非在计算机上安装excel，否则Interop将无法工作。

查看我的库。它的设计是为了快速简便的excel输出，更重要的是性能

using (var ew = new ExcelWriter("C:\\temp\\test.xlsx"))
{
    ew.Write("ID", 1, 1);
    ew.Write("Name", 2, 1);

    ew.Write("1", 1, 2);
    ew.Write("One", 2, 2);

    ew.Write("2", 1, 3);
    ew.Write("Two", 2, 3);
}

替换以下行：

 xlWorkBook.SaveAs("d:\\vdfgdfg.xls", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);

---

使用此行：

xlWorkBook.SaveAs（“d:\\vdfgdfg.xlsx”）
可能的重复项您看过了吗？它是一个不需要excel的组件，并且有一个免费的小表格许可证。您可能需要知道，您只需要在代码中更改
xlWorkBookNormal
到
xlOpenXMLWorkbook
就可以了。当然，您可以将文件名从
xls
更改为
xlsx
：我试过一次dosent work它只保存一个xlsx文件，但无法打开。请尝试我的更新代码。它工作正常。它将在.xlsx中保存excel并将其打开。
