如何通过COM Interop在Excel中获取特定范围？

using Excel = Microsoft.Office.Interop.Excel;

// 创建Excel应用程序对象
Excel.Application excelApp = new Excel.Application();
excelApp.Visible = true;

// 打开Excel应用程序
Excel.Workbook workbook = excelApp.Workbooks.Open("路径\\文件名.xlsx");
Excel.Worksheet worksheet = workbook.Worksheets[1];

// 获取特定范围的数据
Excel.Range range = worksheet.Range["A1:B5"];
object[,] data = range.Value;

// 处理获取到的数据
for (int row = 1; row <= data.GetLength(0); row++)
{
    for (int col = 1; col <= data.GetLength(1); col++)
    {
        object value = data[row, col];
        // 处理数据
    }
}

// 释放资源
workbook.Close();
excelApp.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject(worksheet);
System.Runtime.InteropServices.Marshal.ReleaseComObject(workbook);
System.Runtime.InteropServices.Marshal.ReleaseComObject(excelApp);
