老师给我留的作业。急！！！
题目如下：
设计一个矩阵类，重载其加、减、乘运算符，实现矩阵的相加、相减、相乘，并用Windows Form程序进行测试。
要求：
1）定义一个一维数组，用于存储矩阵的值。
2）定义两个私有成员变量存储矩阵行列值。
3）定义带有set\get访问器的两个属性，对行列值变量进行设置。
4）定义一个索引器返回指定某行某列的矩阵的元素，索引器只有get访问器。
5）定义一个不带参构造函数，根据输入行列属性值随机创建矩阵，随机值为（1-100之间的数）。
6）定义+,-,*的重载方法，实现两个矩阵的相加、相减、相乘。
7）定义一个方法，实现矩阵的转置。
问题：
1.一个不带参数的构造函数，怎么能让数组的行列数自定义呢？怎么可以对矩阵进行各种运算呢？
2.求大神帮帮忙，写个完整的代码我看看。头凸
定义一个不带参构造函数，根据输入行列属性值随机创建矩阵
说的很清楚，通过键盘输入
比如
class Rectangle
{
private int rowcount;
private int colcount;
private int[,] data;
public Rectangle()
{
rowcount = int.Parse(Console.ReadLine());
colcount = int.Parse(Console.ReadLine());
...
}
}
重载+运算
public static Rectangle operator +(Rectangle a, Rectangle b)
{
Rectangle result = new Rectangle(a.rowcount, a.colcount);
for (int i = 0; i < result.rowcount; i++)
for (int j = 0; j < result.colcount; j++)
result.data[i,j] = a.data[i, j] + b.data[i, j];
return result;
}
别的类似
采纳了可以完整写给你。
这个答案都不采纳，我就真的生气了。
