C#:c#读取Excel并显示出来,然后存入数据库.

直接从Excel中读取出来,然后对"供应商" select distinct,然后分别对每个供应商做表.

代码如下:




Code
1


2

protected void Page_Load(object sender, EventArgs e)
3





{
4

DataSet ds = ImportExcel(Server.MapPath("ExcelFile/供应商违约扣款.xls"));
5

GridView1.DataSource = ds.Tables["ExcelInfo"].DefaultView;
6

GridView1.DataBind();
7


8

ToDataBase(ds);
9

}
10


11

private DataSet ImportExcel(string strFileName)
12





{
13

if (strFileName == "") return null;
14

string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" +
15

"Data Source=" + strFileName + ";" +
16

"Extended Properties=Excel 8.0;";
17

OleDbDataAdapter ExcelDA = new OleDbDataAdapter("SELECT trim(供应商) as 供应商,零件名称,型号,批量,下线数,下线率,不合格原因,考核原因,考核金额 FROM [Sheet1$]", strConn);
18

DataSet ExcelDs = new DataSet();
19

try
20





{
21

ExcelDA.Fill(ExcelDs, "ExcelInfo");
22


23

}
24

catch (Exception err)
25





{
26

System.Console.WriteLine(err.ToString());
27

}
28

return ExcelDs;
29

}
30


31


32

private bool ToDataBase(DataSet ds)
33





{
34

DataTable dtSupplier = new DataTable("dtSupplier");
35


36


37

DataView dv = ds.Tables[0].DefaultView;
38


39



string[] column =

{ "供应商" };
40

dtSupplier = dv.ToTable(true, column);
41


42

for (int i = 0; i < dtSupplier.Rows.Count; i++)
43





{
44


45

DataRow[] r = ds.Tables[0].Select("供应商='" + dtSupplier.Rows[i]["供应商"].ToString() + "'");
46


47

//插父表
48


49

for (int j = 0; j < r.Length; j++)
50





{
51

string ItemName = r[j]["零件名称"].ToString();
52

string scale = r[j]["型号"].ToString();
53

string batch = r[j]["批量"].ToString();
54

string downLine = r[j]["下线数"].ToString();
55

string downPercent = r[j]["下线率"].ToString();
56

string outReason = r[j]["不合格原因"].ToString();
57

string reason = r[j]["考核原因"].ToString();
58

string amt = r[j]["考核金额"].ToString();
59


60

//插子表
61

}
62


63

//save
64

}
65

return true;
66

}
