2. 使用方法#

public IEnumerable<T> SqlQuery<T>(string sql, IDbDataParameter[] parameters) { ValidateOperator.Begin() .NotNullOrEmpty(sql, "Sql语句") .NotNull(parameters, "sql对应参数"); var dataParameters = CreateParameter(parameters); return CurrentConnection.Query<T>(sql, dataParameters, CurrentTransaction); }
