C#从Excel填充多维字符串数组

using OfficeOpenXml;

// 读取Excel文件
using (var package = new ExcelPackage(new FileInfo("path/to/excel/file.xlsx")))
{
    // 获取第一个工作表
    var worksheet = package.Workbook.Worksheets[0];

    // 获取数据范围
    var startRow = worksheet.Dimension.Start.Row;
    var endRow = worksheet.Dimension.End.Row;
    var startColumn = worksheet.Dimension.Start.Column;
    var endColumn = worksheet.Dimension.End.Column;

    // 创建多维字符串数组
    var data = new string[endRow - startRow + 1, endColumn - startColumn + 1];

    // 填充数据到数组
    for (int row = startRow; row <= endRow; row++)
    {
        for (int col = startColumn; col <= endColumn; col++)
        {
            data[row - startRow, col - startColumn] = worksheet.Cells[row, col].Value?.ToString();
        }
    }

    // 打印数组内容
    for (int row = 0; row < data.GetLength(0); row++)
    {
        for (int col = 0; col < data.GetLength(1); col++)
        {
            Console.Write(data[row, col] + "\t");
        }
        Console.WriteLine();
    }
}
