在C#的csv文件上执行excel宏

我需要使用C#在现有的csv文件上执行现有的Excel宏(用VB编写,可以使用宏编辑器从Excel复制)。我已经有了可用于在xlsm文件上执行宏的工作代码,如下所示:

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,则它不起作用。所以我需要帮助在csv文件上进行类似的代码工作,或者将csv文件从C#转换为xlsm文件的自动化过程。

此外,能够将VB宏代码作为字符串并且能够使用将字符串作为参数或类似过程的方法运行宏将是有帮助的。

希望以下2个链接可以帮助您打开csv文件,然后以excel格式保存。 所以在那之后你打开excel文件并执行你的任务。

首先,我决定使用以下内容写入包含多个工作表的.xlsx文件,而不是写入csv:

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();
    }
}

然后我使用以下代码创建了工作簿:

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();
}

然后我能够运行刚刚使用我最初发布的代码创建的宏。
