制定条件循环条件？(Making a conditional loop condition?)

 我想创建一个while循环，它将继续在两个条件之一下运行，其中选择的一个被确定为条件。 例如，它将是while(if (c = true) a<b else b<a)的行while(if (c = true) a<b else b<a) 。 这有什么简单的语法吗？ 或者我是否必须采取粗暴的方式并执行以下操作？ 
 
if (c = true) 
{ 
   while(a<b)
   {
   }
} 
else 
{
   while(b<a)
   {
   }
}

I would like to create a while loop where it will keep running under one of two conditions, where the one chosen is determined as a conditional. For example, it would be something along the lines of while(if (c = true) a<b else b<a). Is there any simple syntax for this? Or would I have to go the brute way and do the following? 
 
if (c = true) 
{ 
   while(a<b)
   {
   }
} 
else 
{
   while(b<a)
   {
   }
}
