VB.NET Infinite For Loop
提问by user62572
Is it possible to write an infinite for loop in VB.NET?
是否可以在 VB.NET 中编写无限循环？
If so, what is the syntax?
如果是这样，语法是什么？

Do
Something
Loop
回答by Yes - that Jake.
For i as Integer = 0 To 1 Step 0
If that's not hacky enough, can also write:
如果这还不够hacky，还可以这样写：
For i As Integer = 0 To 2
i -= 1
Next

or
或者
while (true)
end while
ok, proper For answer:
好的，正确的答案：
Dim InfiniteLoop as Boolean = true;
For i = 1 to 45687894
If i = 45687893 And InfiniteLoop = true Then i = 1
End For

Aside from all the many answers given to make a loop run forever, this may just be the first that actually uses the value of Positive Infinity to cap the loop. Just to be safe though, I included an extra option to exit after a given number of seconds so it can measure the speed of your loop.
除了给出的所有使循环永远运行的答案之外，这可能只是第一个实际使用正无穷大的值来限制循环的答案。不过为了安全起见，我添加了一个额外的选项，可以在给定的秒数后退出，以便它可以测量循环的速度。
Sub RunInfinateForLoop(maxSeconds As Integer)
' Attempts to run a For loop to infinity but also exits if maxSeconds seconds have elapsed.
Dim t As Date = Now
Dim exitTime As Date = t.AddSeconds(maxSeconds)
Dim dCounter As Double
Dim strMessage As String
For dCounter = 1 To Double.PositiveInfinity
If Now >= exitTime Then Exit For
Next
strMessage = "Loop ended after " & dCounter.ToString & " loops in " & maxSeconds & " seconds." & vbCrLf &
"Average speed is " & CStr(dCounter / maxSeconds) & " loops per second."
MsgBox(strMessage, MsgBoxStyle.OkOnly, "Infinity Timer")
End Sub

What I do is add a timer then I change the interval to 1 and then I make it enabled then If I want it to constantly check something through the loop I just double click the timer for the timer_tick event then I type what I want. I usually use this for updating the settings if I want it to save every thing.
我要做的是添加一个计时器，然后将间隔更改为 1，然后启用它，然后如果我希望它通过循环不断检查某些内容，我只需双击 timer_tick 事件的计时器，然后输入我想要的内容。如果我希望它保存所有内容，我通常使用它来更新设置。
