A serial port to send: multiple sent files, how to realize the last time send the file before sending the task has been completed?

A serial port receives: multiple will send the file corresponding to a serial port feedback response, how to read sequentially serial port?

CodePudding user response:

Queue of the serial port to send and receive operation, can use SemaphoreSlim, I also am recently used, give you a simple example, (PS: you give you too little)

 
The static SemaphoreSlim _semaphore=new SemaphoreSlim (1);//the number here is the resources of the queue number 
Private void button_Click (object sender, EventArgs e) 
{
For (int I=1; i <6; I++)//
{
Thread _thread=new Thread (()=& gt;//here as your file 
{
GetTest (); 
}); 
_thread. Name="thread" + I; 
_thread. Start (); 
} 

} 
Public void getTest () 
{
_semaphore. Wait (); 
//here is the upload or receive operation 
_semaphore. Release (); 
}
