标题说明了一切,但我会添加一个代码示例,以使其更清晰。
Random r = new Random();
for (int i = r.Next(0, 5); i < r.Next(6, 20); i++)
{
int start = ?
int end = ?
}
答案 0 :(得分:4)
在循环外移动开始和结束的声明:
Random r = new Random();
int start = r.Next(0, 5);
int end = r.Next(6, 20);
for (int i = start; i < end; i++)
{
// Your code goes here.
// If you want to generate a new end criteria for each iteration in a similar way
// as your example, you need to add this to the end of the loop:
end = r.Next(6, 20);
}
在for循环条件块中运行i < r.Next(6, 20)
将为每次迭代生成一个新数字,这可能不是您想要的。
