The variable 'var' is declared but never used
The compiler warns when a variable is declared but not used.
The following sample generates two CS0168 warnings:
public class clx { public int i; } public class clz { public static void Main() { int j = 0; // CS0168, uncomment the following line // j++; clx a; // CS0168, try the following line instead // clx a = new clx(); } }
