Excel数据导入数据库

第一部分：将Excel保存到服务器上：

　 　　　　　　　　string strFileName, UploadedFileName;

DateTime mydatetime = new DateTime();

mydatetime = DateTime.Now;

strFileName = mydatetime.Year.ToString() + mydatetime.Month.ToString() + mydatetime.Day.ToString() + mydatetime.Hour.ToString() + mydatetime.Minute.ToString() + mydatetime.Second.ToString() + ".xls";

string path = HttpContext.Current.Server.MapPath("temp\\");

UploadedFileName = path + strFileName;

FileUpload1.SaveAs(UploadedFileName);

第二部分：读Excel数据到DataSet中

　　　　　 public DataSet open(string _filename)

{

// Response.Write(_filename);

string str = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source='" + _filename + "';Extended Properties='Excel 8.0;HDR=YES;IMEX=1'";

OleDbConnection con = new OleDbConnection();

con.ConnectionString = str;

con.Open();

OleDbCommand cmd = new OleDbCommand("select * from [sheet1$]", con);

OleDbDataAdapter da = new OleDbDataAdapter();

da.SelectCommand = cmd;

DataSet ds = new DataSet();

da.Fill(ds, "sheet1$");

con.Close();

con.Open();

cmd = new OleDbCommand("select * from [sheet2$]", con);

da = new OleDbDataAdapter();

da.SelectCommand = cmd;

da.Fill(ds, "sheet2$");

con.Close();

return ds;

}

第三部分：插入数据到DataSet中

　　　　　//插入数据

DataSet mydataset = open(_filename);

string QYMC = QYMC_XanZe;

string EnterpriseID = QY_ID;

string Areanumber = QY_area;

string FZR = mydataset.Tables[0].Rows[7][3].ToString().Trim();

string LXR = mydataset.Tables[0].Rows[7][6].ToString().Trim();

string LXDH = mydataset.Tables[0].Rows[7][8].ToString().Trim();

string TBRDH = mydataset.Tables[0].Rows[17][8].ToString().Trim();

string TBR = mydataset.Tables[0].Rows[17][6].ToString().Trim();

string TBRQ = mydataset.Tables[0].Rows[4][8].ToString().Trim() + "-" + mydataset.Tables[0].Rows[4][10].ToString().Trim() + "-" + mydataset.Tables[0].Rows[4][12].ToString().Trim();

string CZY = User.Identity.Name.ToString().Trim();

string CZRQ = DateTime.Now.ToString();

string XSE07 = mydataset.Tables[0].Rows[8][3].ToString().Trim();

string XSE07SN = mydataset.Tables[0].Rows[8][8].ToString().Trim();

string XSE08 = mydataset.Tables[0].Rows[9][3].ToString().Trim();

string XSE08SN = mydataset.Tables[0].Rows[9][8].ToString().Trim();

string newID;

newID = "";

string sql = "insert into AY1 (EnterpriseName, EnterpriseID, AreaNumber, FuZR, LianXR, LianXDH, TianBRQ,TianBRXM, TianBDH, CZY, CZRQ, XiaoSE07, XiaoSE07SN, XiaoSE08, XiaoSE08SN) values ";

sql = sql + "('" + QYMC + "','" + EnterpriseID + "','" + Areanumber + "','" + FZR + "','" + LXR + "','" + LXDH + "','" + TBRQ + "','" + TBR + "','" + TBRDH + "','" + CZY + "','" + CZRQ + "','" + XSE07 + "','" + XSE07SN + "','" + XSE08 + "','" + XSE08SN + "')select @@identity";

SqlConnection myconn;

myconn = new SqlConnection(ConfigurationManager.ConnectionStrings["BaseConnectionString"].ConnectionString);

SqlCommand mycommand = new SqlCommand(sql, myconn);

myconn.Open();

string ayid = mycommand.ExecuteScalar().ToString(); //取得新插入记录的ID值

myconn.Close();

　　　　//注意在需要得到插入记录ID时，sql语句(insert sql)select @@identity"和mycommand.ExecuteScalar().ToString()
