You do not need to create new objects for a class to implement a single call.

In a recently created Project, a backend service is written, and many new objects are created in different methods in the demo to call the service, this is a normal thing for my new employee. However, after reading this, my project manager said that this would cause unnecessary waste of system resources, therefore, I am taught a simple method so that I don't need to create a new object every time to implement the call, and add

Public static octopusgameservice Service
{
Get
{
If (service! = NULL)
Return service;
Else
{
Object o = new object ();
Lock (o)
{
Service = new octopusgameservice ();
}
Return service;
}
}
} The method of my service is similar to that of others. In this way, all methods of the service can be called as long as the service is called, thus avoiding the creation of new objects for calling.
