c#restart for循环

Question

所以我有这几行代码:

string[] newData = File.ReadAllLines(fileName)
int length = newData.Length;
for (int i = 0; i < length; i++)
{
    if (Condition)
    {
       //do something with the first line
    }
    else
    {
      //restart the for loop BUT skip first line and start reading from the second
    }
}

我已尝试使用goto,但正如您所看到的,如果我再次启动for循环,它将从第一行开始.

那么如何重新启动循环并更改起始行(从数组中获取不同的键)？

Answer 1

我认为这for loop是一个错误的循环类型,它没有正确表达循环的意图,并且肯定会向我建议你不要乱用计数器.

int i = 0;
while(i < newData.Length) 
{
    if (//Condition)
    {
       //do something with the first line
       i++;
    }
    else
    {
        i = 1;
    }
}

Answer 2

只需更改indexfor循环:

for (int i = 0; i < newData.Length; i++) // < instead of <= as @Rawling commented.
{
    if (//Condition)
    {
       //do something with the first line
    }
    else
    {
      // Change the loop index to zero, so plus the increment in the next 
      // iteration, the index will be 1 => the second element.
      i = 0;
    }
}

请注意,这看起来像一个优秀的意大利面条代码...更改for循环的索引通常表明你做错了什么.
