使用 C# 将多个工作簿合并到一个（新）主工作簿中

Question

我需要一些帮助来将多个工作簿集成到一个主工作簿中。我正在尝试使用以下代码。如果有人可以帮助我解决以下问题，我将不胜感激：

1. 保存包含所有工作表的最终（主）工作簿
2. 不同工作簿中的工作表在复制到主工作簿时不应松散格式。

代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Excel = Microsoft.Office.Interop.Excel;
using Microsoft.Office.Interop.Excel;
using System.IO;

namespace IntegrationMacro
{
    class Program
    {
        static void Main(string[] args)
        {
            Excel.Application app = new Excel.Application();
            app.Visible = true;
            app.Workbooks.Add("");
            app.Workbooks.Add(@"C:\Users\ssehgal\Documents\Excel-Files-For-Macro\WorkBook1.xls");
            app.Workbooks.Add(@"C:\Users\ssehgal\Documents\Excel-Files-For-Macro\WorkBook2.xls");
            for (int i = 2; i <= app.Workbooks.Count; i++)
            {
                for (int j = 1; j <= app.Workbooks[i].Worksheets.Count; j++)
                {
                    Excel.Worksheet ws = (Excel.Worksheet)app.Workbooks[i].Worksheets[j];
                    ws.Copy(app.Workbooks[1].Worksheets[1]);                    
                }
            }

        }

    }
}

var app = new Application() { Visible = true };
var master = app.Workbooks.Add();

// repeat this for each workbook you need to combine...
app.Workbooks.Add(__PATH_TO_THE_WORKBOOK__)
    .Worksheets.Cast<Worksheet>()
    .ToList() // Move() will modify the source of enumeration, so we need to make a temp copy
    .ForEach(x => x.Move(master.Sheets[1]));
