asp.net调用存储过程的参数

SqlCommand command = BuildQueryCommand( connection,storedProcName, parameters );
command.CommandType = CommandType.StoredProcedure;

cmd.Parameters.Add("@articleid",article.articleid);
cmd.Parameters.Add("@title",article.title);
cmd.Parameters.Add("@content",article.content);

取得存储过程的返回值：
在 ado.net 里面获取返回值的方法为(c#):
------------------------------------------------------------
SqlConnection dbconn = new SqlConnection(connStr);

SqlCommand cmd = new SqlCommand("sp_uptmp",dbconn);

cmd.CommandType = CommandType.StoredProcedure;

SqlParameter tmpName = cmd.Parameters.Add("@tmpName",SqlDbType.VarChar);
SqlParameter srcPos = cmd.Parameters.Add("@srcPos",SqlDbType.VarChar);
SqlParameter rtnval = cmd.Parameters.Add("rval",SqlDbType.Int);

tmpName.Direction = ParameterDirection.Input;
srcPos.Direction = ParameterDirection.Input;
rtnval.Direction = ParameterDirection.ReturnValue;

tmpName.Value = "";
srcPos.Value = "";
dbconn.Open();

cmd.ExecuteNonQuery();
dbconn.Close();

tmpid = (int)rtnval.Value; //此处即为返回值
