简单的Excel导出（两种方式）

　　最近项目里面有个周报Excel导出的功能，为了解决这个问题，我显示调研Excel内核的方式实现了，但是被告知该方法有诸多弊端（1、服务器需要装相应版本的Excel；2、如果程序中途出错服务器会有很多Excel进程）；最后用得aspose.cells第三方控件的方式完成。

一、Excel内核方式实现

　　该方法首先需要添加引用Microsoft.Office.Interop.Excel;然后添加同名的using。具体数据插入的逻辑可以忽略，代码如下

View Code

  1  /// Excel导出
  2         /// </summary>
  3         /// <param name="tArys">数据源</param>
  4         /// <param name="templetFileName">模板地址</param>
  5         /// <param name="reportFileName">导出文件临时地址</param>
  6         public static void ExportWeeklyReport(object[] tArys, string templetFileName, string reportFileName)
  7         {
  8             //模板文件
  9             string TempletFileName = templetFileName;
 10             //导出文件
 11             string ReportFileName = reportFileName;
 12 
 13             string strTempletFile = Path.GetFileName(TempletFileName);
 14             //将模板文件复制到输出文件 
 15             FileInfo mode = new FileInfo(TempletFileName);
 16             mode.CopyTo(ReportFileName, true);
 17 
 18             //打开excel
 19             object missing = Missing.Value;
 20             Application app = null;
 21             Workbook wb = null;
 22             Worksheet ws = null;
 23             Range r = null;
 24             //
 25             app = new Microsoft.Office.Interop.Excel.Application();
 26             wb = app.Workbooks.Open(ReportFileName, false, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing);
 27             app.Visible = true;
 28 
 29             //得到WorkSheet对象
 30             ws = (Worksheet)wb.Worksheets.get_Item(2);//2代表第二个sheet
 31 
 32             ////添加或修改WorkSheet里的数据
 33 
 34             //定义一些需要计算的变量
 35             int stafforganizedTotal = 0;
 36             int staffonguardTotal = 0;
 37             int staffontripTotal = 0;
 38             int stafftemporaryTotal = 0;
 39             string requiredtime = string.Empty;
 40 
 41             ///把数据写到Excel//
 42             if (tArys != null)
 43             {
 44                 for (int tis = 0; tis < tArys.Length; tis++)
 45                 {
 46 
 47                     object[,] tAry = (object[,])tArys[tis];
 48                     for (int ti = 0; ti < tAry.GetLength(0); ti++)
 49                     {
 50                         string name = cls.toString(tAry[ti, 0]);
 51                         switch (name)
 52                         {
 53                             case "stafforganized":
 54                                 stafforganizedTotal += cls.getNum(cls.toString(tAry[ti, 1]));
 55                                 break;
 56                             case "staffonguard":
 57                                 staffonguardTotal += cls.getNum(cls.toString(tAry[ti, 1]));
 58                                 break;
 59                             case "staffontrip":
 60                                 staffontripTotal += cls.getNum(cls.toString(tAry[ti, 1]));
 61                                 break;
 62                             case "stafftemporary":
 63                                 stafftemporaryTotal += cls.getNum(cls.toString(tAry[ti, 1]));
 64                                 break;
 65                             case "requiredtime":
 66                                 requiredtime = cls.toString(tAry[ti, 1]);
 67                                 break;
 68                             case "content":
 69                                 ws.Cells[10 + tis, 5] = cls.toString(tAry[ti, 1]);
 70                                 break;
 71                             case "plan":
 72                                 ws.Cells[25 + tis, 5] = cls.toString(tAry[ti, 1]);
 73                                 break;
 74                             case "responsibleperson":
 75                                 ws.Cells[25 + tis, 12] = cls.toString(tAry[ti, 1]);
 76                                 break;
 77                             default:
 78                                 break;
 79                         }
 80 
 81                     }
 82 
 83                 }
 84                 ws.Cells[6, 6] = stafforganizedTotal;
 85                 ws.Cells[6, 8] = staffonguardTotal;
 86                 ws.Cells[6, 10] = staffontripTotal;
 87                 ws.Cells[6, 12] = stafftemporaryTotal;
 88                 ws.Cells[4, 11] = requiredtime;
 89             }
 90 
 91             
 92 
 93             //输出Excel文件并退出
 94             wb.Save();
 95             wb.Close(null, null, null);
 96             app.Workbooks.Close();
 97             app.Application.Quit();
 98             app.Quit();
 99 
100             System.Runtime.InteropServices.Marshal.ReleaseComObject(ws);
101             System.Runtime.InteropServices.Marshal.ReleaseComObject(wb);
102             System.Runtime.InteropServices.Marshal.ReleaseComObject(app);
103 
104             ws = null;
105             wb = null;
106             app = null;
107 
108 
109         }

二、aspose.cell方式实现

　　该方法需要第三方控件的支持，可以在csdn上直接搜索下载，也可以购买。官网上有很多例子，我这个只是最最基础的。具体代码如下。（记得加引用后加using）

 1  /// <summary>
 2         /// 生成Excel到指定目录
 3         /// </summary>
 4         /// <param name="tArys"></param>
 5         /// <param name="regulardatetext"></param>
 6         public static void ExportWeeklyReport(object[] tArys, string templetFileName, string reportFileName)
 7         {
 8 
 9 
10             /////参考Aspose.Cells官网的例子http://www.aspose.com/demos/.net-components/aspose.cells/csharp/quick-start/data/hello-world.aspx
11            
12             //打开excel
13 
14             Workbook wb = new Workbook(templetFileName);//打开对应地址的excel模板
15             Worksheet ws = wb.Worksheets[1];//第二个sheet，从0开始
16             Cells cells = ws.Cells;//获取对应的cells 的引用
17 
18             ////定义几个需要计算的变量           
19             int stafforganizedTotal = 0;
20             int staffonguardTotal = 0;
21             int staffontripTotal = 0;
22             int stafftemporaryTotal = 0;
23             string requiredtime = string.Empty;
24 
25             ///把数据写到Excel//
26             if (tArys != null)
27             {
28                 for (int tis = 0; tis < tArys.Length; tis++)
29                 {
30 
31                     object[,] tAry = (object[,])tArys[tis];
32                     for (int ti = 0; ti < tAry.GetLength(0); ti++)
33                     {
34                         string name = cls.toString(tAry[ti, 0]);
35                         switch (name)
36                         {
37                             case "stafforganized":
38                                 stafforganizedTotal += cls.getNum(cls.toString(tAry[ti, 1]));
39                                 break;
40                             case "staffonguard":

42                                 break;

45                                 break;
46                             case "stafftemporary":
