 8             }
 9             using (ExcelPackage package = new ExcelPackage(newFile))
10             {
11                 ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("test");
12                 worksheet.Cells[1, 1].Value = "名称";
13                 worksheet.Cells[1, 2].Value = "价格";
14                 worksheet.Cells[1, 3].Value = "销量";
15 
16                 worksheet.Cells[2, 1].Value = "大米";
17                 worksheet.Cells[2, 2].Value = 56;
18                 worksheet.Cells[2, 3].Value = 100;
19 
20                 worksheet.Cells[3, 1].Value = "玉米";
21                 worksheet.Cells[3, 2].Value = 45;
22                 worksheet.Cells[3, 3].Value = 150;
23 
24                 worksheet.Cells[4, 1].Value = "小米";
25                 worksheet.Cells[4, 2].Value = 38;
26                 worksheet.Cells[4, 3].Value = 130;
27 
28                 worksheet.Cells[5, 1].Value = "糯米";
29                 worksheet.Cells[5, 2].Value = 22;
30                 worksheet.Cells[5, 3].Value = 200;
31 
32                 package.Save();
33             }

 9             {
10                 //读取sheet未test1的内容
11                 ExcelWorksheet worksheet = package.Workbook.Worksheets["test1"];
12                 //ExcelWorksheet worksheet = package.Workbook.Worksheets[1];
13                 //ExcelWorksheet worksheet = package.Workbook.Worksheets.First();
14                 string tmp = worksheet.Cells[1, 1].Text;
15                 Console.WriteLine(tmp);
16             }
17             Console.WriteLine("ok");
