使用c＃将公式写入现有excel表单的语法是什么？

我试图将我在VBA中编写的内容转换为使用c＃的可执行文件。 我的想法是将某些公式写入现有的Excel工作簿。 我有用于写入新工作簿的语法，但不能写入现有的工作簿。

Answer 1

尝试和testing

using System; using System.Windows.Forms; using System.IO; using Excel = Microsoft.Office.Interop.Excel; Namespace WindowsFormsApplication5 { public partial class Form1 : Form { Public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { Microsoft.Office.Interop.Excel.Application xlexcel; Microsoft.Office.Interop.Excel.Workbook xlWorkBook; Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet; object misValue = System.Reflection.Missing.Value; xlexcel = new Excel.Application(); // Open a File xlWorkBook = xlexcel.Workbooks.Open("C:\\MyFile.xlsx", 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0); // Set Sheet 1 as the sheet you want to work with xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1); ////////////////////////////////////////////////////////// // REST OF THE CODE HERE TO INTERACT WITH THE WORKSHEET// ////////////////////////////////////////////////////////// //Once done close and quit Excel xlWorkBook.Close(true, misValue, misValue); xlexcel.Quit(); releaseObject(xlWorkSheet); releaseObject(xlWorkBook); releaseObject(xlexcel); } private void releaseObject(object obj) { try { System.Runtime.InteropServices.Marshal.ReleaseComObject(obj); obj = null; } catch (Exception ex) { obj = null; MessageBox.Show("Unable to release the Object " + ex.ToString()); } finally { GC.Collect(); } } } }

您可以通过Workbooks.Open方法执行此操作， 本文提供了详细信息。

 string workbookPath = "c:/SomeWorkBook.xls"; Excel.Workbook excelWorkbook = excelApp.Workbooks.Open(workbookPath, 0, false, 5, "", "", false, Excel.XlPlatform.xlWindows, "", true, false, 0, true, false, false); 

然后，您可以通过Worksheets属性引用特定Worksheets 。

 Excel.Sheets excelSheets = excelWorkbook.Worksheets;
