C#.Net导入导出Excel
关于Excel在软件系统中的作用 , 如果是大型项目的话 , 一般会用Excel做配置 . 游戏公司尤其是偏好这个. 想想看 , 要策划人员去写XML 或者 JSON 配置文件 , 这个我觉得有点为难策划 . 而且容易配置错误. 如果让他们利用Excel呢 ? 如果你觉得不安全 , 完全可以将Excel导出 , 保存为二进制文件 , 供程序员调用 .
1, 需要应用 : using Microsoft.Office.Interop.Excel;
一 : 新建一个Excel
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Office.Interop.Excel;
namespace MyExcel
{
class Program
{
static void Main(string[] args)
{
Application excel = new Application();
//设置2个工作表
excel.SheetsInNewWorkbook = 2;
//添加一个工作簿
excel.Workbooks.Add();
//获得第一个工作表
Worksheet sheet1 = (Worksheet)excel.ActiveWorkbook.Worksheets[1];
sheet1.Name = "Xiaoxue";
sheet1.Cells[1,1] = "Eisa";
sheet1.Cells[3, 1] = "1222211111";
sheet1.Cells[2, 2] = new DateTime();
// 样式设置
Range range = excel.Range[excel.Cells[1, 1], excel.Cells[1, 9]];
range.Font.Bold = true;
range.Font.ColorIndex = 4;
range.Interior.ColorIndex = 1;
range.Borders.LineStyle = XlLineStyle.xlDash;
excel.Range[excel.Cells[2, 1], excel.Cells[9, 1]].NumberFormatLocal = "@"; // 电话好码
excel.Range[excel.Cells[2, 2], excel.Cells[9, 2]].NumberFormat = "yyyy-m-d";//日期显示格式
excel.Visible = true;
}
}
}
看看结果:
现在 , 去选择一个目标Excel , 并且把其数据读出来
①:得到Excel文件路径
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace ExcelTest.com
{
/// <summary>
/// 返回一个Excel文件的路径
/// </summary>
public class ExcelPath
{
private string basePath;
/// <summary>
///
/// </summary>
/// <param name="basePath"> 初始路径 如 : "C:\\" </param>
public ExcelPath(string basePath)
{
this.basePath = basePath;
}
public string getExcelFileName()
{
if (this.basePath != "")
{
// 需要引用 : System.Windows.Forms
OpenFileDialog excelDialog = new OpenFileDialog();
excelDialog.InitialDirectory = this.basePath;
excelDialog.Filter = "Microsoft Excel files (*.xls)|*.xlsx";
if (excelDialog.ShowDialog() == DialogResult.OK)
{
if ((excelDialog.OpenFile()) != null)
{
return excelDialog.FileName;
}
}
return string.Empty;
}
else
{
return string.Empty;
}
}
}
}
②:核心读取目标Excel的数据
关于如何关闭Excel的进程 , 需要引用 : System.Runtime.InteropServices;
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 ExcelTest.com;
using Microsoft.Office.Interop.Excel;
using System.Runtime.InteropServices;
namespace ExcelTest
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
//getExcelPath();
handlerExcelFile("Sheet1");
}
/// <summary>
/// 获得目标Excel路径
/// </summary>
/// <returns></returns>
private string getExcelPath()
{
// 初始化实例
ExcelPath openExcel = new ExcelPath( "e:\\" );
string excelPath = openExcel.getExcelFileName();
Console.WriteLine("我得到的Excel文件路径{0}", excelPath);
return excelPath;
}
/// <summary>
/// 获得Excel应用实例
/// </summary>
private Microsoft.Office.Interop.Excel.Application getExcelApp()
{
//创建Excel
Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();
// 打开选择的excel文件
excel.Workbooks.Open( getExcelPath() );
return excel;
}
/// <summary>
///
/// </summary>
/// <param name="sheetName"> 工作表的名称 </param>
private void handlerExcelFile( string sheetName )
{
Microsoft.Office.Interop.Excel.Application excel = getExcelApp();
// 定义工作表
Worksheet sheet = null;
//查找目标工作表
foreach (Worksheet wsheet in excel.ActiveWorkbook.Sheets)
{
if (sheetName == wsheet.Name)
{
sheet = wsheet;
break;
}
}
if (sheet != null)
{
Console.WriteLine("测试数据 : {0}", Convert.ToString( (sheet.Cells[1, 1] as Range).Text ));
}
//关闭进程
Marshal.ReleaseComObject(sheet);
Marshal.ReleaseComObject(excel);
sheet = null;
excel = null;
GC.Collect();
}
}
}
结果 测试 :
