you can "call/use" other classes provided they are all within the same namespace.

sorry i dint get you...

==="class is user defined"===

i want to include the class

so that i can use the functions directly defining in that class...
without calling using the object of that class....

this may help:
http://www.csharp-station.com/Tutorials/Lesson07.aspx

here we are creating the object of the class, i guess so...

but i want to call the functions directly without declaring the object of that class.

see:


i have two classes named class1, class2.

class1 have two functions
c1f1
c1f2

class2 also have two functions
c2f1
c2f2

here is the third class3
which i want to call these functions

eg:

public class class3:class1
{
public constructor()
{
}

public void c3f1()
{
int a=c1f1(); // here i m calling function c1f1defining in class1 without creating the object of the class1
}
}


now i want to use the function defining in the class2( in the same manner-- without creating the object of the class2)


how can i do???

right at the top of code under your 'using......' statements:

namespace whatever
{

your code

}

now do that to all your classes. then each class can call methods from other classes (you have to specify which, where and when) also ensure methods are public

sorry
but i dint get u again...

lol ok no worries.

namespace whatever
{
class1
your code

}


namespace whatever
{
class2
your code

}


namespace whatever
{
class3
your code
}

You need to place your classes within a namespace, and all within the same namespace if you do not wish to declare them separately.

So instead of declaring all these specifics, you just create them all in one namespace, then reference the name space to the page using "using".
