Getters Setters

I am confused to no end.

The code that seems to have to work the same – works different.
An explanation would be nice.

The following code:

public int Pages
{
    get { return _pages; }
    set
    {
        if (value < 1)
        {
            _pages = 1;
        }
        else { }
        _pages = value;
    }
}

In case i set page value to 0 or a negative value – the value is set to 1.
Works just fine.

It also works just fine in the following example:

public int Pages
{
    get { return _pages; }
    set
    {
        if (value < 1)
        {
            _pages = 1;
        }
        else 
        {
            _pages = value; 
        }
        
    }
}

However.

 public string Title
 {
     get { return _title; }
     set
     {
         if (value == "")
         {
             _title = "Default";
         }
         else
         {
             
         }
         _title = value;
     }
 }

This block of code, which essentially should do the exact same thing, except it checks if the string is empty, and sets the string value to "Default" – fails to do so.
Whenever the string value is empty – it remains empty.

Now if i move the _title = value; into the body of the else statement – it works fine.

Working code example:

public string Title
{
    get { return _title; }
    set
    {
        if (value == "")
        {
            _title = "Default";
        }
        else
        {
            _title = value;
        }
        
    }
}

Why is that so?
How come the same code with different data type gives different outcome?
What is the part i am missing here?

If you are kind enough to explain – thanks a lot.

>Solution :

The code is correct… in:

if (value == "")
         {
             _title = "Default";
         }
         else
         {
             
         }
         _title = value;

_title always will be value.. because if set "" it set twice:

_title = "Default"
AND
_title = value ("")

then always will be VALUE
