Can we force Garbage Collector to run?

Yes, by calling GC.COLLECT() method we can force garbage collector to run, but this is not recommended, instead use Dispose method.

However, you can suggest to the GC that it might be a good time to perform garbage collection by using the GC.Collect() method. Note that this is just a suggestion, and the GC may or may not perform garbage collection immediately.

Here's an example:

csharp

using System;

public class Program
{
    public static void Main()
    {
        // Create some objects
        for (int i = 0; i < 10000; i++)
        {
            new MyClass();
        }

        Console.WriteLine("Objects created");

        // Suggest to the GC that it's a good time to collect
        GC.Collect();
        GC.WaitForPendingFinalizers();

        Console.WriteLine("Garbage collection completed");
    }
}

public class MyClass
{
    // A class with no additional implementation
    // Just to create some objects for demonstration purposes
}

In this example, we create multiple instances of the MyClass object in a loop. After creating the objects, we suggest to the GC that it's a good time to perform garbage collection by calling GC.Collect(). The GC.WaitForPendingFinalizers() method is called to wait for any finalizers (destructors) to complete before continuing execution.

However, it's important to note that explicitly forcing garbage collection is generally not recommended in most scenarios. The .NET runtime and GC are designed to handle memory management automatically, and they have sophisticated algorithms to determine the best time to collect garbage. Manual intervention in garbage collection can disrupt the performance and efficiency of the runtime. It is generally more effective to let the GC manage memory on its own, focusing on writing efficient and memory-conscious code instead.
