How to write multithreaded need?

CodePudding user response:

You define a Boolean outside keyforbreak;
Private bool KeyforBreak;
While ()//read from the database user information
{
//your code
}

CodePudding user response:

Wasn't written
Private bool KeyforBreak=false;
While ()//read from the database user information
{
//your code
If (KeyforBreak)
{
KeyforBreak=false;
break;
}
}
If (the Console. ReadKey (true). The Key==ConsoleKey. Enter)
{
KeyforBreak=true;
}

CodePudding user response:

Don't mislead people, and thread no anything to do,

Console. Readkey method will block the current thread waiting for input, just enter the specified characters can exit the loop and you just write the judge at the edge of the cycle in vitro, so that it can never be performed here, should be like this:
While (true)
{
. .

If (the Console. ReadKey (true). The Key==ConsoleKey. Enter)
{
break;
}
}

This also not line, you perform to input do not input will not down here,

CodePudding user response:

Multi-threaded positive solution, a thread to handle the original logic, a thread to judge the keyboard input

CodePudding user response:

Feeling is the cancellation of the thread and suspended,

Sure to add a thread, you can't get to receive input from the user,

I this version, self-test OK

CodePudding user response:

The landlord did not describe the problem clearly, is constantly taking data for processing, press the return key to suspend? Or take a, and then wait for the enter key to suspend?
If the former, then you need to use the thread processing, if the latter, so don't need a thread to handle,
