在excel文件中添加宏

Question

我有以下宏

Sub test()
    Dim xsheet As Worksheet
    For Each xsheet In ThisWorkbook.Worksheets
        xsheet.Select
        With xsheet.UsedRange
            .Value = .Value
        End With
    Next xsheet      
End Sub

有没有办法将它添加到 excel 文件并使用 c# 执行它？

任何帮助将不胜感激。

1) 这是我使用 .Net 参考适用于 Excel 的代码： Microsoft.Office.Interop.Excel v14（不是 ActiveX COM 参考）：

using System;
using Microsoft.Office.Interop.Excel;

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
    RunVBATest();
}

public static void RunVBATest()
{
    Application oExcel = new Application();
    oExcel.Visible = true;
    Workbooks oBooks = oExcel.Workbooks;
    _Workbook oBook = oBooks.Open("C:\\temp\\Book1.xlsm");

    // Run the macro.
    RunMacro(oExcel, new Object[] { "TestMsg" });
    //Run a macro with parameters        
    //RunMacro(oExcel, new Object[] { "ShowMsg", "Hello from C# Client", "Demo to run Excel macros from C#" });

    // Quit Excel and clean up
    oBook.Saved = true;
    oBook.Close(false);
    oExcel.Quit();
    System.Runtime.InteropServices.Marshal.ReleaseComObject(oBook);
    System.Runtime.InteropServices.Marshal.ReleaseComObject(oBooks);
    System.Runtime.InteropServices.Marshal.ReleaseComObject(oExcel);
}

private static void RunMacro(object oApp, object[] oRunArgs)
{
    oApp.GetType().InvokeMember("Run",
        System.Reflection.BindingFlags.Default |
        System.Reflection.BindingFlags.InvokeMethod,
        null, oApp, oRunArgs);

}
}
}
}

2) 确保将宏代码放入模块（全局 BAS 文件）中..

Public Sub TestMsg()

MsgBox ("Hello Stackoverflow")

End Sub

3) 确保启用对 VBA 项目对象模型的宏安全和信任访问：

Siddharth Rout 的解决方案从这个MSDN issue 中提取

这应该可行：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Excel = Microsoft.Office.Interop.Excel;

namespace WindowsFormsApplication2
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            //~~> Define your Excel Objects
            Excel.Application xlApp = new Excel.Application();

            Excel.Workbook xlWorkBook;

            //~~> Start Excel and open the workbook.
            xlWorkBook = xlApp.Workbooks.Open("E:\\Users\\Siddharth Rout\\Desktop\\book1.xlsm");

            //~~> Run the macros by supplying the necessary arguments
            xlApp.Run("test");

            //~~> Clean-up: Close the workbook
            xlWorkBook.Close(false);

            //~~> Quit the Excel Application
            xlApp.Quit();

            //~~> Clean Up
            releaseObject(xlApp);
            releaseObject(xlWorkBook);
        }

        //~~> Release the objects
        private void releaseObject(object obj)
        {
            try
            {
                System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
                obj = null;
            }
            catch (Exception ex)
            {
                obj = null;
            }
            finally
            {
                GC.Collect();
            }
        }
    }
}

如果你的宏有参数，让我们说：

Sub ShowMsg(msg As String, title As String)
    MsgBox msg, vbInformation, title
End Sub

您必须将xlApp.Run("test"); 更改为xlApp.Run("ShowMsg", "Hello from C# Client", "Demo to run Excel macros from C#");
