C# break 和 continue


C# break

您已经在本教程的前面章节中看到了 break 语句的使用。它用于“跳出” switch 语句。

break 语句也可用于跳出 **循环**。

此示例在 i 等于 4 时跳出循环

示例

for (int i = 0; i < 10; i++) 
{
  if (i == 4) 
  {
    break;
  }
  Console.WriteLine(i);
}

C# continue

continue 语句会在满足指定条件时中断循环的一次迭代,并继续执行循环的下一轮迭代。

此示例跳过 4 的值

示例

for (int i = 0; i < 10; i++) 
{
  if (i == 4) 
  {
    continue;
  }
  Console.WriteLine(i);
}

在 while 循环中使用 break 和 continue

您也可以在 while 循环中使用 breakcontinue

break 示例

int i = 0;
while (i < 10) 
{
  Console.WriteLine(i);
  i++;
  if (i == 4) 
  {
    break;
  }
}
