c# - How to make a property with a if-statement

my question is, if it's possible, to do something like this:

public Class Test
{
  public int Number { get; set; }
  private string text;

  public string Text
  {
    if (Number > 5)
    {
      set {text = value;}
      get {return text;}
    }
  }
}

No, but you could do something like:

public class Test {
        public int Number { get; set; }
        private string _Text;
        public string Text {
            get {
                if(Number > 5) {
                    return _Text;
                } else {
                    //DEFAULT value here. 
                    return null;
                }                
            }
            set {
                if(Number > 5) {
                    _Text = value;
                } else {
                    //DEFAULT Value. 
                    _Text = null;
                }
            }
        }
    }

I would also check out Preprocessor Directives if you are using Visual Studio. These might be more helpful depending on how you are trying to use the code.
