从C#对csv文件执行excel宏

本文关键字：执行 excel 文件 csv | 更新日期: 2023-09-27 18:27:46

我需要使用C#在现有csv文件上执行现有Excel宏（用VB编写，可以使用宏编辑器从Excel复制）。我已经有了可以用来在xlsm文件上执行宏的工作代码，它看起来像这样：

using System;
using Excel = Microsoft.Office.Interop.Excel;
namespace MacroBuddy
{
    public class test
    {
        public static void go_Macro()
        {
            object oMissing = System.Reflection.Missing.Value;
            //create new Excel application instance
            Excel.Application oExcel = new Excel.Application();
            oExcel.Visible = true;
            Excel.Workbooks oBooks = oExcel.Workbooks;
            Excel._Workbook oBook = null;
            string path = @"C:'Users'user'Desktop'test.csv";
            //open file located at path
            oBook = oBooks.Open(path, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing);
            //run Macro by referencing file and the name of the Macro
            RunMacro(oExcel, new Object[] { "test.xlsm!TestMacro" });
            //save and close workbook
            oBook.Save();
            oBook.Close(false, oMissing, oMissing);
            System.Runtime.InteropServices.Marshal.ReleaseComObject(oBook);
            oBook = null;
            System.Runtime.InteropServices.Marshal.ReleaseComObject(oBooks);
            oBooks = null;
            oExcel.Quit();
            System.Runtime.InteropServices.Marshal.ReleaseComObject(oExcel);
            oExcel = null;
            GC.Collect();
        }
        private static void RunMacro(object oApp, object[] oRunArgs)
        { oApp.GetType().InvokeMember("Run", System.Reflection.BindingFlags.Default | System.Reflection.BindingFlags.InvokeMethod, null, oApp, oRunArgs); }
        static void Main()
        { go_Macro(); }
    }
}

但是，如果指定的文件是csv文件，则不起作用。因此，我需要帮助使类似的代码在csv文件上工作，或者自动将csv文件从C#转换为xlsm文件。

此外，能够将VB宏代码作为字符串，并能够使用将字符串作为参数或类似过程的方法来运行宏，这将是很有帮助的。

从C#对csv文件执行excel宏

希望以下2个链接将帮助您打开csv文件，然后将其保存为excel格式。然后打开excel文件，执行任务。

我没有首先写入csv，而是决定使用以下内容写入包含多张图纸的.xlsx文件：

public class test
{
    object missing = Type.Missing;
    public test()
    {
        Excel.Application XL = new Excel.Application();
        oXL.Visible = false;
        Excel.Workbook WB = XL.Workbooks.Add(missing);
        Excel.Worksheet Sheet = WB.ActiveSheet as Excel.Worksheet;
        oSheet.Name = "First sheet";
        oSheet.Cells[1, 1] = "Written on first sheet";
        Excel.Worksheet Sheet2 = WB.Sheets.Add(missing, missing, 1, missing) 
                    as Excel.Worksheet;
        Sheet2.Name = "Second sheet";
        Sheet2.Cells[1, 1] = "Written on second sheet";
        string fileName = @"C:'temp'SoSample.xlsx";
        oWB.SaveAs(fileName, Excel.XlFileFormat.xlOpenXMLWorkbook,
            missing, missing, missing, missing,
            Excel.XlSaveAsAccessMode.xlNoChange,
            missing, missing, missing, missing, missing);
        oWB.Close(missing, missing, missing);
        oXL.UserControl = true;
        oXL.Quit();
    }
}

然后我用下面的代码创建了工作簿：

private void button1_Click(object sender, System.EventArgs e)
{
         Excel.Application oExcel;
         Excel.Workbook oBook;
         VBIDE.VBComponent oModule;
         Office.CommandBar oCommandBar;
         Office.CommandBarButton oCommandBarButton;
         String sCode;
         Object oMissing = System.Reflection.Missing.Value;
         // Create an instance of Excel.
         oExcel = new Excel.Application();
         // Add a workbook.
         oBook = oExcel.Workbooks.Add(@"C:'Users'user'Downloads'test.xlsm");
         // Create a new VBA code module.
         oModule = oBook.VBProject.VBComponents.Add(VBIDE.vbext_ComponentType.vbext_ct_StdModule);
         sCode =
         //paste in your macro here, with each line followed by a new line
         "Sub TestMacro()'r'n" +
         "Columns('"D:D'").Select'r'n" +
         "Selection.Copy'r'n" +
         "Columns('"F:F'").Select'r'n" +
         "ActiveSheet.Paste'r'n" +
         "Application.CutCopyMode = False'r'n" +
         "ActiveSheet.Range('"$F$1:$F$542'").RemoveDuplicates Columns:=1, Header:=xlNo'r'n" +
         "Range('"F1'").Select'r'n" +
         "ActiveCell.FormulaR1C1 = '"Unique Query'"'r'n" +
         "Range('"F2'").Select'r'n" +
         "End Sub";
         // Add the VBA macro to the new code module.
         oModule.CodeModule.AddFromString(sCode);

         // Make Excel visible to the user.
         oExcel.Visible = true;
         // Set the UserControl property so Excel won't shut down.
         oExcel.UserControl = true;
         // Release the variables.
         oModule = null;
         oBook = null;
         oExcel = null;             
         // Collect garbage.
         GC.Collect();
}

然后，我可以运行刚刚用我最初发布的代码创建的宏。
