Force function to return value and make compile error C#

You could convert this to a property instead of a method:

  public string myString
  {
    get
    {
      return "Blah";
    }
  }

Then you can't compile if you simply call the property:

myString.myString; //Results in "Only assignment, call, increment, decrement, await, and new object expressions can be used as a statement" Error
