C#(sharp) corner help :)

this is my c sharp winform + console. the 2 winform are admin control and the passenger registration.
the flow must be.
if i will input passenger information text box value and press the request button the c# console will notify the admin control that there is a reservation request. and send the information to admin control.
now the value of text boxes input at the passenger client will show at the label in the admin control.
its like passenger registration form nametext box=name) - admin control form namelabel=name).

some one told me that it need to use XML but i dont know how..


advance thanks sa mga tutulong po..
