c# - Why would this simple code cause a stack overflow exception?

Question

The stack overflow exception was thrown in the setter method of this property:

public string TimeZone
{
    get
    {
        if (TimeZone == null)
            return "";

        return TimeZone;
    }
    set { TimeZone = value; }
}

"An unhandled exception of type 'System.StackOverflowException' occurred"

I do not see any straightforward recursion here.

If there are problems with the code, what should I be using instead to correct it?

Answer 1

set { TimeZone = value; }

The setter is recursive.

You must use a field like:

string _timeZone;

public string TimeZone
{
    get
    {
        if (_timeZone== null)
            return "";

        return _timeZone;
    }
    set { _timeZone= value; }
}
