Loading a .dat file using FileStream error

I am trying to load my playerData.dat file and display a float variable to a textbox in Unity, however, I am getting an error on line 27.

Code (csharp):

1.  
2. // Code hidden as problem now solved
3.  

Line 27 is coming up with an error saying "InvalidCastException: Cannot cast from source type to destination type." Does anyone know why this is?

 

Anyone have any ideas? I'm at a complete loss here

 

If you replace line 27 with

Code (csharp):

1. Debug.Log(bf.Deserialize(file).GetType().ToString());

What kind of output do you then get?

 

My output is 'PlayerData', followed by a NullReferenceException saying 'Object reference not set to an instance of an object'

 

Mate I'm getting the idea that the problem might be that your save method isn't compatible with your load method. Could you post your save method to see if we can spot something off there?

 

I seem to have found the problem lyed with this bit of code, so I commented it out and it now works as it should

Code (csharp):

1.  
2. [Serializable]
3. class PlayerData
4. {
5.   public float rightTotalDisplacement;
6.   public float leftTotalDisplacement;
7. }
8.  

My Save and Load method works fine on another C# script I had, I just didn't realise this bit of code wasn't needed when you're not saving
