Question

How would you achieve thread synchronization in ASP.NET? Please describe at least two different techniques.

Answer 1

Thread synchronization in ASP.NET can be achieved using various techniques, such as:

1. Monitor class: This approach uses the Monitor.Enter and Monitor.Exit methods to lock a shared resource, ensuring that only one thread can access it at a time. Example:

object _lock = new object();

void AccessResource()

{

Monitor.Enter(_lock);

try

{

// Access shared resource here

}

finally

{

Monitor.Exit(_lock);

}

}

2. Mutex class: A named system-wide mutex allows for inter-process synchronization. It works similarly to the Monitor class but operates across multiple processes. Example:

Mutex _mutex = new Mutex(false, "Global\\MyNamedMutex");

void AccessResource()

{

_mutex.WaitOne();

try

{

// Access shared resource here

}

finally

{

_mutex.ReleaseMutex();

}

}

These techniques help prevent race conditions and ensure data consistency when multiple threads access shared resources.
