winform中的whileloop导致应用程序崩溃！为什么？ [英] whileloop in winform cause app to crash ! why ?

问题描述

你好朋友，


由于某些原因我在winform中执行这段代码时它会立即崩溃应用程序。


基本上我正在尝试为基于客户端/服务器的应用程序管理线程池。


while（true）


{


while（！client.Pending（））


{


Thread.Sleep（1000）;


}


ConnectionThread newconnection = new

ConnectionThread（）;


newconnection.threadListener = this.client;


ThreadPool.QueueUserWorkItem（新

WaitCallback（newconnection.HandleConnection） ）; b / b

调试后，它一进入while循环就会崩溃。


任何智慧的碎屑都赞赏


thankyou

Hello friends,

for some reason when I execute this piece of code in a winform it
immediately crashes the app.

baseically I''m trying to manage a thread pool for a client/server based app.

while(true)

{

while (!client.Pending())

{

Thread.Sleep(1000);

}

ConnectionThread newconnection = new
ConnectionThread();

newconnection.threadListener = this.client;

ThreadPool.QueueUserWorkItem(new
WaitCallback(newconnection.HandleConnection));

}

after debugging it seems to crash as soon as it enters the while loop.

any crumbs of wisdom is appreciated

thankyou

Tom

推荐答案

while循环是一个无限循环。

while（true）

要求你使用break关键字手动取消循环;


while（true）

{

Something（）;

if（IsFinished（））

{

break;

}

}


while（true）有点受欢迎。

就个人而言，我从不使用这样的声明，除非我真的必须

因为我不认为它很干净。

相反，我在while语句中形成一个条件。

while（！ IsFinished（））

{

Something（）;

}

The while loop is an infinite loop.
while (true)
requires you to manually cancel the loop by using break keyword;

while (true)
{
Something();
if (IsFinished())
{
break;
}
}

The while (true) is somewhat popular.
Personally, i never use a such statement unless i really have to
because i dont think it is very clean.
Instead, i form a condition in the while statement.
while (! IsFinished())
{
Something();
}

朋友们好，

由于某些原因，当我在winform中执行这段代码时，
会立即崩溃应用程序。

基本上我是'我试图管理基于
app的客户端/服务器的线程池。
while（true）


while（！client。等待（））



Thread.Sleep（1000）;

}

ConnectionThread newconnection = new
ConnectionThread（）;

newconnection.threadListener =
this.client;
ThreadPool.QueueUserWorkItem（新

WaitCallback（newconnection.HandleConnection） ）;

调试后，一旦进入while循环，它似乎就会崩溃。

Tom，


你有什么例外得到些什么？另外，在不知道由于线程池线程被调用而被调用回来的

代码，这很难说。

Tom,

What is the exception that you are getting? Also, without knowing the
code that is called back into as a result of the thread pool thread being
called, it''s hard to tell.
