代码如下，请指点。

  int[] type = new int[1]{ 0};

string[] value = new string[1] { "Text"};
            object  filtertype;
            object filtervalue;
             filtertype = type ;
            filtervalue = value;
            double[] t1 = new double[3] { 10, 20, 0 };
            double[] t2 = new double[3] { 100, 100, 0 };

            //获取图名图号
            int num = sortend.Count;
            for (int i = 0; i < num; i++)  
            {
  
                Sel.Select(mode, t1, t2, filtertype ,filtervalue ); //此句中总提示filtertype参数有错？？？？
                string temp = Sel.Item(0).ToString();
            }
