Use of possibly unassigned field 'field'
A field in a structure was used without being initialized. The field must first be initialized.
The following sample generates CS0170:
public struct error { public int i; } public class CMyClass { public static void Main() { error e; // uncomment the next line to resolve this CS0170 // e.i = 0; System.Console.WriteLine( e.i ); // CS0170 } }
