C#：如何将开关与 if 语句组合在一起？
C#: How can I combine a switch with an if-statement?
问：
我需要将开关与 if 语句结合起来。
我该怎么做？我想做这样的事情：
switch (periodtype)
{
if(starttime>endtime)
{
;
}
else
{
case 0: nextRunTime = nextRunTime.AddHours(period); break;
case 1: nextRunTime = nextRunTime.AddMinutes(period); break;
case 2: nextRunTime = nextRunTime.AddSeconds(period); break;
}
}

if(starttime>endtime)
{
// Stuff
}
else
{
switch (periodtype)
{
case 0: nextRunTime = nextRunTime.AddHours(period); break;
case 1: nextRunTime = nextRunTime.AddMinutes(period); break
case 2: nextRunTime = nextRunTime.AddSeconds(period); break;
}
}
诸如此类？

有什么问题：
if(starttime<=endtime)
{
switch (periodtype)
{
case 0: nextRunTime = nextRunTime.AddHours(period); break;
case 1: nextRunTime = nextRunTime.AddMinutes(period); break;
case 2: nextRunTime = nextRunTime.AddSeconds(period); break;
}
}

嗯，回答太晚了
这不是更容易吗：
if (starttime <= endtime)
{
switch (periodtype)
{
case 0: nextRunTime = nextRunTime.AddHours(period); break;
case 1: nextRunTime = nextRunTime.AddMinutes(period); break;
case 2: nextRunTime = nextRunTime.AddSeconds(period); break;
}
}
