C# order of function modifiers

Hi,

I would like to know if there is a standard to set the order of function modifiers in C#. i.e.

public static void AssignTo(this int me, int value)
{}

static public void AssignTo(this int me, int value)
{}

this both work well, BUT

when I code:

public void static AssignTo(this int me, int value)
{}

I receive the following error:

Member modifier 'static' must precede the member type and name

and

Method must have a return type

Any help/link would be appreciated. TIA.
