I'm currently creating an application in C# using Visual Studio. Visual studio for mac reviews. I want to create some code so that when a variable has a value of 1 then a certain piece of code is carried out.I know that I can use an if statement but the problem is that the value will be changed in an asynchronous process so technically the if statement could be ignored before the value has changed.

Is it possible to create an event handler so that when the variable value changes an event is triggered? If so, how can I do this?
It is completely possible that I could have misunderstood how an if statement works! Any help would be much appreciated.

Seems to me like you want to create a property. https://uoigsq.weebly.com/blog/gopro-studio-for-mac-2017.
This allows you to run some code any time the property value changes. You could raise an event here, if you wanted.

You can use a property setter to raise an event whenever the value of a field is going to change.
You can have your own EventHandler delegate or you can use the famous System.EventHandler delegate.

If you want to catch an event in a different thread that it's being raised you must be careful not to change the state of objects that are defined in another thread which will cause a cross thread exception to be thrown. To avoid this you can either use an Invoke method on the object that you want to change its state to make sure that the change is happening in the same thread that the event has been raised or in case that you are dealing with a Windows Form you can use a BackgourndWorker to do things in a parallel thread nice and easy.

The .NET framework actually provides an interface that you can use for notifying subscribers when a property has changed: System.ComponentModel.INotifyPropertyChanged. This interface has one event PropertyChanged. Its usually used in WPF for binding but I have found it useful in business layers as a way to standardize property change notification.
