什么是C＃中的Property Accessor递归？

Question

What is Property Accessor Recursion in C#? I see articles of how to resolve it, but want a pure technical definition of what it is.

Resources on how to resolve it:

c# property setter body without declaring a class-level property variable

Answer 1

It becomes clearer if you think of the getters and setters as methods (they really are methods in the background - C# just hides that from you).

• Whenever you retrieve the value of a property, you are calling the get method
• Whenever you set the value of a property, you are calling the set method

So if you have a property that looks like this:

public string MyProperty {
    get {
        return this.MyProperty;
    }
    set {
        this.MyProperty = value;
    }
}

That is really like having these two methods:

string get_MyProperty() {
    return get_MyProperty();
}

void set_MyProperty(string value) {
    set_MyProperty(value);
}

You will notice that both cases will result in infinite recursion that will end with a stack overflow .

So Don't Do That™
