使用vs2008建立小网站，实现将excel文件中的内容一次性全部导入到SQL中，希望能有人帮助我。 --------------------编程问答-------------------- 如果数据格式标准的话，直接用oledbconnection来打开excel,将数据将数据读出来，然后再导入到sql数据库中。提供思路，代码要自己研究。 --------------------编程问答-------------------- http://blog.csdn.net/fangxinggood/archive/2005/06/18/397315.aspx --------------------编程问答-------------------- 嘿嘿 --------------------编程问答-------------------- 环境：c#.2005+Access+ Sql
一、把DataTable插入数据库
public static void DataTableToDB()
{
string _strExcelFileName = @"D:\example.xls";
DataTable dtExcel = ExcelToDataTable(_strExcelFileName,"Sheet1");
for (int i = 0; i < dtExcel.Rows.Count; i++)
{
InsertDataToAccess(dtExcel.Rows[i][0].ToString(), float.Parse(dtExcel.Rows[i][1].ToString()));
}
}
二、把Excel数据读入DataTable
public static DataTable ExcelToDataTable(string strExcelFileName, string strSheetName)
{
string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + strExcelFileName + ";" +"Extended Properties=Excel 5.0;";
string strExcel = string.Format("select * from [{0}$]", strSheetName);
DataSet ds = new DataSet();
using (OleDbConnection conn = new OleDbConnection(strConn))
{
conn.Open();
OleDbDataAdapter adapter = new OleDbDataAdapter(strExcel, strConn);
adapter.Fill(ds, strSheetName);
conn.Close();
}
return ds.Tables[strSheetName];
}
三、向Access数据库表插入数据
public static void InsertDataToAccess(string _strPara,float _fPara)
{
OleDbConnection oleDbConn = new OleDbConnection();
oleDbConn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\ExcelData.mdb;User Id=admin;Password=;";
oleDbConn.Open();
string strInsertString = "INSERT INTO tb_excelData (strCollumn1,fCollumn2) VALUES (@strCollumn1,@fCollumn2)";
OleDbCommand oComm = new OleDbCommand(strInsertString, oleDbConn);
oComm.Parameters.Add("@strCollumn1", OleDbType.Char , 50);
oComm.Parameters["@strCollumn1"].Value = _strPara;
oComm.Parameters.Add("@fCollumn2", OleDbType.Double);
oComm.Parameters["@fCollumn2"].Value = _fPara;
ocomm.ExecuteNonQuery();
oleDbConn.Close();
} --------------------编程问答--------------------

2、使用OleDb+sql语句读取web服务器上的excel文件
3、将读取的数据写入到sql server 数据库
4、将web服务器上的临时excel删除
部分代码如下：
string filename = FileUpload1.PostedFile.FileName.Substring(FileUpload1.PostedFile.FileName.LastIndexOf("\\"));
FileUpload1.PostedFile.SaveAs(Server.MapPath("fileupload\\") + filename);//上传文件
string conn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("fileupload\\") + filename + ";Extended Properties=Excel 8.0";

OleDbCommand olecommand = new OleDbCommand(sqlin, new OleDbConnection(conn));
OleDbDataAdapter adapterin = new OleDbDataAdapter(olecommand);
DataSet dsin = new DataSet();
adapterin.Fill(dsin);
DataTable dtin = dsin.Tables[0];//连接并读取excel数据
