排序

Question

string chan = "@F0AFF2550@C0ACC2210@Y0AYY1700@B0A901030@H0A851450@K0A801360@L0A751280@M0A701190";
 string[] arr = chan.Split(new string[] { "@" }, StringSplitOptions.RemoveEmptyEntries);
如何实现后四位的最小值到大排序显示B0A901030,M0A701190......在DATAGRID里面？
DATAGRID里面显示如下
B0A901030
M0A701190
K0A801360
H0A851450
......

Answer 1

//截取自字符串
        string.substring(4,4);
//装换类型 排序

Answer 2

        public class MyComparer : IComparer
        {
            public int Compare(object x, object y)
            {
                int a = Convert.ToInt32(x.ToString().Substring(5));
                int b = Convert.ToInt32(y.ToString().Substring(5));
                if (a > b)
                    return 1;
                else if (a < b)
                    return -1;
                else
                    return 0;            }
        }
            string chan = "@F0AFF2550@C0ACC2210@Y0AYY1700@B0A901030@H0A851450@K0A801360@L0A751280@M0A701190";
            string[] arr = chan.Split(new string[] { "@" }, StringSplitOptions.RemoveEmptyEntries);            Array.Sort(arr, new MyComparer());
            DataTable dt = new DataTable();
            dt.Columns.Add(new DataColumn("ID",typeof(string)));            foreach(string s in arr)
            {
                DataRow dr = dt.NewRow();
                dr["ID"] = s;
                dt.Rows.Add(dr);
            }            dataGridView1.DataSource = dt;

Answer 4

可以放到ArrayList中，调用SORT方法
