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

Question

Do I need to declare a class-level variable to hold a property, or can I just refer to self.{propertyname} in the getter/setter?

In other words, can I d

Answer 1

You should have a backing variable. Take a closer look:

get { return this.mongoFormId; }

Is going to call the getter on mongoFormId, which will call that code again, and again, and again! Defining a backing variable will avoid the infinite recursive call.

Answer 2

You can either use automatic accessors or implement your own. If you use automatic accessors, the C# compiler will generate a backing field for you, but if you implement your own you must manually provide a backing field (or handle the value some other way).

private string _mongoFormId;

public string mongoFormId 
{
    get { return this._mongoFormId; }
    set 
    {
        this._mongoFormId = value;
        revalidateTransformation();
    }
}

UPDATE: Since this question was asked, C# 6.0 has been released. However, even with the new syntax options, there is still no way to provide a custom setter body without the need to explicitly declare a backing field.
