asp.net （C#）怎么初始化一个二维字符串数组
asp.net （C#）怎么初始化一个二维字符串数组，让它的初始值都是0. 如string num[i,j]的初始值都是0。

------解决方案--------------------
string[,] num=new string[,]{{"0","0","0"},{"0","0","0"},{"0","0","0"}}
------解决方案--------------------

C# code

for (int x = 0; x < i; x++)
    for (int y = 0; y < j; y++)
        num[i, j] = "";
