3-tier architecture in C#[^]

hope it helps :)

Add Class Library as BL and call it from ASP.Net.

in asp.net there 3 layers
business layer is one of that,it's nothing but class where your logic comes.
they are BAL(Business Access Layer) ,BOL(Business Object Layers) create class starts with bol or bal this will automatic get place in APP code


regards
vipul

create class and name it as you want, by it will be " BOLpage.cs"

then define every variable used in your program as

private vST;

then create property procedures ( which will get and set the values) as

public String ST
{
      get
      {
         return vST;
      }
      set
      {
          vST=value;
       }
}

and define functions for your programs as

public void fun1(class_name objectOf_class_name)
{

}
