    Please make more effort to format your code. The indentation is all over the place at the moment. The code you've provided won't give a NullReferenceException, either. Please show your full stack trace. – Jon Skeet Jul 09 '15 at 08:15

    You are missing `;` behind `"Demo Player"`. – Dzienny Jul 09 '15 at 08:16

    Provide compiling code that demonstrates the issue reproducibly. It sounds like nitpicking, but it's also important to follow [capitalization-](https://msdn.microsoft.com/en-us/library/vstudio/ms229043(v=vs.100).aspx)(f.e. uppercase first letter in `player_name`) and [naming-conventions](https://msdn.microsoft.com/en-us/library/ms229045(v=vs.110).aspx)(f.e. no underscores). – Tim Schmelter Jul 09 '15 at 08:24

You're either accessing the static class member before it was set to "Demo Player". For example, you are trying accessing My_Static_Data_Class.player_name in Program.cs code before it calls the main form from the Main[] method. Alternatively you're might be setting My_Static_Data_Class.player_name to null elsewhere in code and then accessing it.

Check all the references in code editor and follow it up. To do this, right click on My_Static_Data_Class.player_name in Visual Studio editor, and choose Find All References menu item.
