windows form application

how do we create a share them for all page in windows forms application?

You create a infrastructure or framework dll that you reference in your winforms application - that way you have a centralized point where you build your own custom controls / components etc.

this them impliment with skin or schema or stylesheet

Winforms doesnt bother with schema, stylesheets.
you are looking for control properties - you can specify color settings etc as globals in your infrastructure where controls can inherit from
global::

also this them include button,menu,combobox,textbox and...

You can override the default controls - for instance if you want a tectbox with a limited amount of text for input like a,b,c,d,e,f and 0-9
you can place it in your custom framework then inherit from it

TextCustomControl = new TextCustomControl();
and not TextBox TextBox1 = new Textbox();

if all else fails - drink a oxford dictionary.
