对于循环
for循环执行代码块，直到指定的条件为false。虽然for循环看起来像while循环 ，但开发人员应该正确使用它们。当迭代次数可变时使用while循环，否则使用for循环。 for循环的常见用途是数组迭代。 1
句法
for ((Initial variable); (condition); (step))
{
(code)
}
C＃for循环由三个表达式和一些代码组成。
描述
- 初始变量 ：您的起始状态，例如int i = 0;
- 条件 ：当此条件为真时，代码将继续运行，例如i <= 5;
- 步骤 ：初始变量的增量或减量，例如i ++或i- = 2。
例
int[] array = { 1, 2, 3, 4, 5 };
for (int i = 0; i < array.Length; i++)
{
Console.WriteLine("Item on index {0} is {1}", i, array[i]);
}
输出：
> Item on index 0 is 1
> Item on index 1 is 2
> Item on index 2 is 3
> Item on index 3 is 4
> Item on index 4 is 5
