一、开工必备

1、micorosoft office2007

2、VS2010、Oracle 11

二、界面

三、内部代码

(1)获取数据库连接，定义全局变量

private static string connString = System.Configuration.ConfigurationSettings.AppSettings[ "connStr" ];
         DataSet dTable;

(2)选择Excel文件导入dataset

if(openFileDialog1.ShowDialog()==DialogResult.OK)
             {
                 ctlPath.Text = openFileDialog1.FileName;
                 ExceltoDataSet(ctlPath.Text);
             }

(3)加载Excel文件数据

public DataSet ExceltoDataSet(string path)
         {
             MessageBox.Show( "正在获取数据....请稍候" );
             //
             string strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source="+path+";Extended Properties='Excel 12.0;HRD=Yes;IMEX=1';" ;
             OleDbConnection conn = new OleDbConnection(strConn);
             conn.Open();
            System.Data.DataTable schemaTable = conn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables,null);
            
            string tableName = schemaTable.Rows[0][2].ToString().Trim();
            
             string strExcel =  " " ;
             OleDbDataAdapter myCommand = null;
             DataSet ds = null;
             strExcel = "Select * from [" + tableName + "]";
             myCommand = new OleDbDataAdapter(strExcel,strConn);
             ds = new DataSet();
             try
             {
                 myCommand.Fill(ds, tableName);
             }
             catch(Exception ex)
             {
                 MessageBox.Show(ex.Message);
             }
                 dTable = ds;
           
             if (ds != null)
             {
                 button2.Visible = true;
               
         
             }
             return ds;
     
        
         }

(4)显示导入数据

DataTable dt = dTable.Tables[0];

try {

for (int i = 0; i > 0; i++)

{

dt.Rows.Remove(dt.Rows[i]);

}

dataGridView1.DataSource = dt;

} catch (Exception ex)

{

throw ex;

}

(5)将数据导入数据库

1. DataTable dt = dTable.Tables[0];
2. for (int i = 1; i < dt.Rows.Count; i++)
3. {
4. string sql1 = string.Format( "insert  /*+nologging*/ into TPB_CARCONFIG(LINERNUM,RESID,CARTYPEID,RESFNAME,RESURL,BRAND" +
5. " values('" + dTable.Tables[0].Rows[i][0] + "','101','" + dTable.Tables[0].Rows[i][0] + "','汽车之家','www.autohome.com.cn/', " +
6. " '" +dTable.Tables[0].Rows[i][181]+ "','" +dTable.Tables[0].Rows[i][182]+ "','" +dTable.Tables[0].Rows[i][183]+ "','" +dTable.Tables[0].Rows[i][1]+ "')" );
7. OracleConnection oconn = new OracleConnection(connString);
8. oconn.Open();
9. OracleCommand cmd;
10. try {
11. cmd = new OracleCommand(sql1.ToString(), oconn);
12. int a = Convert.ToInt32(cmd.ExecuteNonQuery());
13. if (a > 0)   {

1. }
2. } catch (Exception ex)  {
3. 注：这里收集重复信息的编号，保存到txt文本
4. string path =  "c:错误信息.txt" ;
5. FileStream fs = new FileStream(path,FileMode.Append);
6. StreamWriter sw = new StreamWriter(fs);
7. sw.WriteLine( "Excel编号"  + dTable.Tables[0].Rows[i][0]+ "数据已与数据表中重复" );
8. sw.Close();
9. fs.Close();
10. fs.Dispose();
11. continue;
12. }
13. oconn.Close();
14. }

注：该程序我没有使用线程，所以在导入大量数据的时候，winform窗体假死，但是程序依然在奋斗，请耐心等待复活。

四、效果图
      1、导入前

2、导入后→点击显示数据
