asp.net中如何调用sql server的存储过程？

这例子很好，慢慢研究！

// type to match a SQL database 'varchar' field of 12 characters

objParam.Direction = ParameterDirection.Input;
objParam.Value = "1861002882"; // create a new Parameter object named 'Title' with the correct data
// type to match a SQL database 'varchar' field of 50 characters
// and specify that it's an output parameter (so no value required)
objParam = objCommand.Parameters.Add("Title", OleDbType.VarChar, 50);
objParam.Direction = ParameterDirection.Output; // create another output Parameter object named 'Date' with the correct
// data type to match a SQL database 'datetime' field

}
catch (Exception objError)
{
// display error details
outError.InnerHtml = "<b>* Error while accessing data</b>.<br />"
+ objError.Message + "<br />" + objError.Source;
return; // and stop execution
} // collect the values of the output parameters - note the use of
// the ToString method as they will contain DBNull if there was no
// match for the ISBN and this will cause an error if displayed
string strTitle = objCommand.Parameters["Title"].Value.ToString();
string strDate = objCommand.Parameters["Date"].Value.ToString();
outOutParams.InnerHtml = "Title='" + strTitle + "'   Date=" + strDate; }

Dim myConn As SqlClient.SqlConnection
        Dim myCommand As SqlClient.SqlCommand
        Dim myReader As SqlClient.SqlDataReader
        Dim myOutput As ParameterDirection
        Dim Sql As String
        Dim ConnStr As String = Application("Connt_Login") '数据库连接串
        myConn = New SqlClient.SqlConnection(ConnStr)
        myConn.Open()
        myCommand = New SqlClient.SqlCommand("online", myConn)
        myCommand.CommandType = System.Data.CommandType.StoredProcedure
        myCommand.Parameters.Add("@S_Id", SqlDbType.Char).Value = "111"
        myCommand.Parameters.Add("@P_Id", SqlDbType.Char).Value = "-100"
        myCommand.Parameters.Add("@Lb", SqlDbType.Char).Value = "T"
        myCommand.Parameters.Add("@CountUser", SqlDbType.Int).Value = 0        myReader = myCommand.ExecuteReader
asp.net 高级编程  又说到这个，但都不详细，而且没有电子版的！：（从这个例子应该大概能看出用法了吧？
to  milchcow:
  myCommand = New SqlClient.SqlCommand("online", myConn)
这个online是不是sql server中的存储过程？
online就是sqlserver中的存储过程！
