asp.net 怎么实现在网页中把用户提交的excel文件中的数据导入到sql数据库中

请讲详细点，有代码最好，谢谢，如果答案有很大帮助，我会追加给分的

Answer 1

一、把Excel转换成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];
}

二、向Access数据库插入数据的方法
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();
}

三、将Excel转换成DataTable，然后插入数据库
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[0].ToString(), float.Parse(dtExcel.Rows[1].ToString()));
}
}
