 1  DataTable table = new DataTable();
 2            table.Columns.Add("ID", typeof(string));
 3            table.Columns.Add("Name", typeof(string));
 4
 5            DataRow row = table.NewRow();
 6
 7            row["ID"] = "All";
 8            row["Name"] = "全部";
 9            table.Rows.Add(row);
            row = table.NewRow();
            row["ID"] = "Add";
            row["Name"] = "添加";
            table.Rows.Add(row);
            row = table.NewRow();
            row["ID"] = "Update";
            row["Name"] = "修改";
            table.Rows.Add(row);
            row = table.NewRow();
            row["ID"] = "Delete";
            row["Name"] = "删除";
            table.Rows.Add(row);

 

 

//Dictionary 的用法
  Dictionary<string, int> dic = new Dictionary<string, int>();
        private int  GetLevel(string id)
        {
            int num = 0;
            foreach(KeyValuePair<string, int> d in dic)
            {               
                if (d.Key.ToString() == id) {
                    num =Convert.ToInt32(d.Value);
                }    
            }
            return num;
        }
