     There are times when we may want a property to be read-only – such that it can’t be
changed.
This is where read-only properties come into the picture. A Read Only property is one
which includes only the get accessor, no set accessor.

Example:
public readOnly int empid
{
    get
    {
        return empid;
    }
}


    Similar to read-only properties there are also situations where we would need
something known as write-only properties. In this case the value can be changed
but not retrieved. To create a write-only property, use the WriteOnly keyword and
only implement the set block in the code as shown in the example below.

public writeOnly int e
{
    set
    {
        e = value
    }
}
