C#如何定义动态double二维数组

[zcdg909]

如题

[xutao888]

一般用ArrayList或者HashTable来做动态数组

[Fibona]

double[,] darr=new double[100,100];

即然是动态的,用泛型来解决相对更简单

List<T>就行

List<double> list = new List<double>();
            list.Add(0.1);
            list.Add(0.2);
            //....


            foreach (double i in list)
            {
                Console.WriteLine(i.ToString());
            }
                Console.ReadKey();

[即济]

double [,] = new double[,];

ArrayList:
double[] db1 = new double[];
ArrayList db2 = new ArrayList();
db2.add(db1);

二维的呀?晕.没看清题
二维的用泛型的List也可以
如下例:

 List<List<double>> list = new List<List<double>>();

            List<double> t = new List<double>();
            t.Add(1.1);
            t.Add(1.2);
            list.Add(t);

            List<double> t2 = new List<double>();
            t2.Add(2.1);
            t2.Add(2.2);
            list.Add(t2);

            Console.WriteLine(list[0][0].ToString());
            Console.WriteLine(list[0][1].ToString());
            Console.WriteLine(list[1][0].ToString());
            Console.WriteLine(list[1][1].ToString());

            Console.ReadKey();

楼上的都说完了 呵呵

[5isoft]

double [,] sub1 = new double[1,2];
