我要评论在程序循环中初始化
可以使用此处所示的嵌套循环初始化数组中的所有元素：
int[,] arr7 = new int[5,4];
for(int i=0; i<5; i++)
{
for(int j=0; i<4; j++)
{
arr7[i,j] = 0; // initialize each element to zero
}
}
system.array 类
在 .net framework 中，数组是作为 array 类的实例实现的。此类提供了许多有用的方法，如 sort 和 reverse。
下面的示例演示了使用这些方法是多么的简单。首先，使用 reverse 方法将数组元素反转，然后使用 sort 方法对它们进行排序：
class arraymethods
{
static void main()
{
// create a string array of size 5:
string[] employeenames = new string[5];
// read 5 employee names from user:
system.console.writeline("enter five employee names:");
for(int i=0; i<employeenames.length; i++)
{
employeenames[i]= system.console.readline();
}
// print the array in original order:
system.console.writeline("\narray in original order:");
foreach(string employeename in employeenames)
{
system.console.write("{0} ", employeename);
}
// reverse the array:
system.array.reverse(employeenames);
// print the array in reverse order:
system.console.writeline("\n\narray in reverse order:");
foreach(string employeename in employeenames)
{
system.console.write("{0} ", employeename);
}
// sort the array:
system.array.sort(employeenames);
// print the array in sorted order:
system.console.writeline("\n\narray in sorted order:");
foreach(string employeename in employeenames)
{
system.console.write("{0} ", employeename);
}
}
}
输出
enter five employee names:
luca
angie
brian
kent
beatriz
array in original order:
luca angie brian kent beatriz
array in reverse order:
beatriz kent brian angie luca
array in sorted order:
angie beatriz brian kent luca
