求动态数组实例

Question

我需要用一个二维的动态数组，谁能给个实例参照一下，包括创建，添加记录，遍历数组，数组的生命周期是页面内，WinForm的
急用，谢谢大家了

Answer 1

我用的是1.1，所以list用不了~~

Answer 2

（1）定义一个结构或类即可搞定。
public class abc
{
   public List<object> obj1 = new List<object>();
   public List<object> obj2 = new List<object>();
}
创建，添加记录，遍历数组应该自己可以搞定吧。

Answer 3

你还用VS2003呵。你可以用下面一维的改写成二维的。
        private void SubReDim(ref int[] List, bool IsIncrease)
        {
            //
            int iCount = 0;            try
            {
                if (List == null || List.Length == 0)
                {
                    int[] tmpList = new int[1];
                    List = tmpList;
                }
                else
                {
                    if (IsIncrease)
                    {
                        iCount = List.Length;
                        int[] tmpList = new int[iCount + 1];
                        Array.Copy(List, tmpList, List.Length);
                        List = tmpList;
                    }
                    else
                    {
                        iCount = List.Length - 1;
                        int[] tmpList = new int[iCount + 1];
                        Array.Copy(List, tmpList, tmpList.Length);
                        List = tmpList;
                    }
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message.Trim(), "SubReDim Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
                return;
            }
        }

Answer 4

object [,] a = new object[m, n];

Answer 5

    class DTClass
    {
        private string tabName;
        private string selString;        public DTClass(string name, string strSQL)
        {
            this.tabName = name;
            this.selString = strSQL;
        }        public string Name
        {
            get { return tabName; }
            set { tabName = value; }
        }        public string SelString
        {
            get { return selString; }
            set { selString = value; }
        }
    }    class DTClassIndexer //索引器, 用于对 DTClass 进行操作
    {
        private ArrayList arrDTClass;
        public DTClassIndexer()
        {
            arrDTClass = new ArrayList();
        }        //声明一个索引器
        public string this[string name]
        {
            get
            {
                foreach (DTClass cs in arrDTClass)
                {
                    if (cs.Name == name)
                    {
                        return cs.SelString;
                    }
                }
                return string.Empty;
            }
            set
            {
                arrDTClass.Add(new DTClass(name, value)); //调用: arr["ss"]="asdfasfa";
            }
        }        public int Count() //返回长度
        {
            return arrDTClass.Count;
        }
    } static void Main()
{
            ds["ss"] = "sss";
            Console.WriteLine(ds.Count());
            ds["sss"] = "sssss";
            Console.WriteLine(ds.Count());
}
