Solution 1

You're getting a stack overflow because of this section:

C#

public int val
{
get
{
return val == 10 ? 1 : 0;
}
set
{
_val = value;
}
}

Your get method is referencing the property name and not the private variable name. This means when you get the value of val, your code goes into a never ending loop as the result references itself. In .Net this will eventually cause a stack overflow exception.

Solution 2

Hi,

Try:

C#

public int val
{
    get
    {
        return _val == 10 ? 1 : 0;
    }
    set
    {
        _val = value;
    }
}

Just add an underscore before val == 10 ? 1 : 0;

Hope this helps.
