Property readonly .NET

Mads Torgersen (C # design team) has announced that this is a feature that is being considered for the next release (C # 6.0?).

Currently:

private readonly int x;
public int X { get { return x; } }

With C # 6.0:

public int X { get; } = x;  

Source: Probable C # 6.0 features illustrated

Just use the readonly modifier in a field:

public readonly int Numero;

For example. Thus, Numero can only be assigned a value in the class constructor.

Note that readonly is not used on a property; To make a property read-only, set its setter to private :

public int Numero { get; private set; }

One way is to create a property without Set

public int PropriedadeReadOnly
{
    get { return propriedadeReadOnly; }
}

And a second form, which allows the property to be written only once, usually in the constructor of a class. It is using readonly

public readonly PropriedadeRead;

To set a read-only priority, we have two options, either to place the get in the declaration of the property or to declare the set as private.

In the case of VB net, you can write like this:

Public ReadOnly valor_pi as Single = 3.1415
