Asp.Net将Excel数据导入Sql Server数据库的的例子

在网上找到一个Asp.Net将Excel数据导入Sql Server数据库的的例子,是调用存储过程的

前言:cmd.CommandText="Proc_Address";这句话是调用存储过程"Proc_Address"

该存储过程代码为:

CREATE Proc Proc_Address @CardNo char(20),@ToAddress char(50),@CCAddress char(50) ,@YYYYMM char(12)

as

declare @strSql   char (400)

set @strSql = 'Insert into EmailAddress' + @YYYYMM + ' values(''+@CardNo+'',''+@ToAddress+'',''+@CCAddress+'',''+'1')'   --插入一条记录

exec (@strSql)

GO

private void Button1_Click(object sender, System.EventArgs e)

{

CreateTable();

//先将EXCEL导入到数据库,一:先把EXCEL导入dateView,二:然后将dateView里的数据导入到数据库里面

//EXCEL 的连接串

string sConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" +

"Data Source=" + File1.PostedFile.FileName.ToString() + ";" +

"Extended Properties=Excel 8.0;";

//建立EXCEL的连接

OleDbConnection objConn = new OleDbConnection(sConnectionString);

objConn.Open();

OleDbCommand objCmdSelect =new OleDbCommand("SELECT * FROM [Sheet1＄]", objConn);

OleDbDataAdapter objAdapter1 = new OleDbDataAdapter();

objAdapter1.SelectCommand = objCmdSelect;

DataSet objDataset1 = new DataSet();

objAdapter1.Fill(objDataset1, "XLData");

// DataGrid1.DataSource = objDataset1.Tables[0].DefaultView; //测试代码,用来测试是否能读出EXCEL上面的数据

// DataGrid1.DataBind();

DataTable dt = objDataset1.Tables[0];

DataView myView = new DataView(dt);

//SQL SERVER的数据库连接

SqlConnection conn;

string dns =System.Configuration.ConfigurationSettings.AppSettings["ConStr"];//连接串

conn=new SqlConnection(dns);

SqlCommand cmd =conn.CreateCommand();

cmd.CommandType =CommandType.StoredProcedure;

cmd.CommandText="Proc_Address";

int count=0;//用来记录出错的条数

try

{

foreach (DataRowView myDrv in myView)

{

count++;

//要关闭上一次的SQL Server的连接

if (conn.State.ToString()!="Closed")

conn.Close();

//每一次都要清空所有的CMD的参数

cmd.Parameters.Clear();

//执行存储过程

//首先获得参数 共 3个

//@CardNo,@ToAddress,@CCAddress

SqlParameter paraCardNo =cmd.Parameters.Add("@CardNo",SqlDbType.Char);

SqlParameter paraToAddress =cmd.Parameters.Add("@ToAddress",SqlDbType.Char);

SqlParameter paraCCAddress =cmd.Parameters.Add("@CCAddress",SqlDbType.Char);

SqlParameter paraYYYYMM =cmd.Parameters.Add("@YYYYMM",SqlDbType.Char);

//表示是输出参数

paraCardNo.Direction = ParameterDirection.Input;

paraToAddress.Direction = ParameterDirection.Input;

paraCCAddress.Direction = ParameterDirection.Input;

paraYYYYMM.Direction = ParameterDirection.Input;

//参数赋值

paraCardNo.Value = myDrv[0].ToString().Trim();

paraToAddress.Value = myDrv[1].ToString().Trim();

paraCCAddress.Value = myDrv[2].ToString().Trim();

paraYYYYMM.Value = ddlYear.Items[ddlYear.SelectedIndex].Value + ddlMonth.Items[ddlMonth.SelectedIndex].Value;

conn.Open();

cmd.ExecuteNonQuery();//写入SQL数据库

}

}

catch

{

Page.Response.Write("alert('第"+count.ToString()+"条数据出错!');");

objConn.Close();//关闭EXCEL的连接

}

objConn.Close();//关闭EXCEL的连接
