C#讀取Excel表格的數據

1、創建工程后，需要下載 EPPlus.dll 添加到工程中，這里有一個下載地址:https://download.csdn.net/download/myunity/10784634

2、下面僅實現讀取Excel表格的列數據:

using System;
using System.Collections.Generic;
using System.IO;
using OfficeOpenXml;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            List<string> list = GetExcelColumnValue(@"D:\UniuAndroid5.6.2\plan\配置表\excel\t_equip.xlsx", 1, 3);

            for (int i = 0; i < list.Count; ++i)
            {
                Console.WriteLine(list[i]);
            }

            Console.ReadKey();
        }

        /// <summary>
        /// 讀取Excel表格列數據
        /// </summary>
        /// <param name="path">Excel表格所在的路徑</param>
        /// <param name="sheetIndex">需要讀取的Sheet頁碼序號</param>
        /// <param name="columnIndex">需要讀取的列序號</param>
        /// <returns></returns>
        static List<string> GetExcelColumnValue(string path, int sheetIndex, int columnIndex)
        {
            List<string> list = new List<string>();

            FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read);
            ExcelPackage excel = new ExcelPackage(fileStream);
            ExcelWorksheet sheet = excel.Workbook.Worksheets[sheetIndex];

            try
            {
                for (int i = 5; i <= sheet.Dimension.End.Row; i++)
                {
                    var cell = sheet.Cells[i, columnIndex];
                    if (cell != null && cell.Value != null)
                        list.Add(cell.Value.ToString());
                }
            }
            catch
            {
                throw;
            }
            finally
            {
                sheet.Dispose();
                excel.Dispose();
                fileStream.Dispose();
            }

            return list;
        }
    }
}
