How do I call a parameterized function in C# thread?
Pass parameter to thread in C# – 2 ways
- 1- Using Thread. Start() method:
- Program Example – Using Thread. Start(Object) method in C#:
- 2- Using ParameterizedThreadStart delegate: Pass user defined thread function to ParameterizedThreadStart delegate and assign delegate object to Thread class object.
Why does a delegate need to be passed as a parameter to the thread class constructor?
It means the delegate points to a function that the thread has to execute. In simple words, we can say that all the threads that we create require an entry point (i.e. a pointer to the function) from where it should execute. This is the reason why threads always require a delegate.
How do you use Threadpool?
To use thread pools, we first create a object of ExecutorService and pass a set of tasks to it. ThreadPoolExecutor class allows to set the core and maximum pool size. The runnables that are run by a particular thread are executed sequentially. Method Description newFixedThreadPool(int) Creates a fixed size thread pool.
What is thread start?
start() method causes this thread to begin execution, the Java Virtual Machine calls the run method of this thread. The result is that two threads are running concurrently: the current thread (which returns from the call to the start method) and the other thread (which executes its run method).
How do threads communicate with each other C#?
Methods for interthread communication In other words, this method makes the thread that has called the Wait() method to wait for the other thread to complete its work on the same object. This static method notifies the first thread in the waiting queue of threads about a change in the locked object’s state.
How data is passed to the thread?
To pass data into the thread we will simply pass it as an input parameter to the method that is being started as a new thread. To get the data from the thread a delegate callback method will be used. First, we will make a regular method that takes in an input parameter.
Is abort thread safe?
Well, the problem with Thread. Abort() is that will abort the thread possibly in the middle of work. That might cause your state to be corrupted. That’s why is advisable to use a volatile bool flag to control the thread, and let the thread finish its task gracefully, but based on that flag.
What is thread delegate?
A delegate is the . NET version of a type safe function pointer. All threads require an entry point to start execution. By definition when a primary thread is created it always runs Main() as it’s entry point.
What type of object is required when a thread that requires a single parameter?
When you start a thread that requires a single parameter use ParameterizedThreadStart delegate.
How to start a thread from a parameterizedthreadstart?
Console.WriteLine ( “Start ()” ); } } Start () Start () Start () Start () DONE ParameterizedThreadStart. This starts a thread with a target method. We can then pass this instance to the Thread constructor. The target method is then invoked upon starting the Thread. Example We create 4 ParameterizedThreadStarts, then start and join 4 threads.
How does the compiler infer the parameterizedthreadstart delegate?
The Visual Basic and C# compilers infer the ParameterizedThreadStart delegate from the signatures of the DoWork and DoMoreWork methods, and call the correct constructor. Thus, there is no explicit constructor call in the code.
What is the difference between parameterizedthreadstart and domorework?
The first ParameterizedThreadStart delegate is represented by the static DoWork method and the second is represented by the instance DoMoreWork method. Both methods match the ParameterizedThreadStart delegate signature; that is, they have a single parameter of type Object and don’t return a value.
How do you pass a method to a thread in C?
In Visual Basic, use the AddressOf operator when passing your method to the Thread constructor; for example, Dim t As New Thread (AddressOf ThreadProc). In C#, simply specify the name of the thread procedure. The compiler selects the correct delegate constructor.
