No.C# sharp does not support multiple inheritance .
Single inheritance is only possible in c#

Yes Supports multiple inheritance,
by using interface

c# doesnot provide multiple inheritance as it can lead to 
abiguity for compiler
but we can use multiple inheritance in c# in interface 
concept

HI GUYS,

C#.NET SUPPORTS ONLY SINGLE LEVEL OF INHERITENCE AND 
MULTILEVEL OF INHERITENCE IS SUPORTED THROUGH INTERFACES

REG
ARAVIND REDDY

no it does not support multiple inheritance

hai friends,
we can achieve this multiple inheritence through 
interfaces..
ex:interface I1
{
  void add();

}
interface I2
{
  void add();
}

class sample:I1,I2
{
I1.add()
{
console.write("this is add method");
}
 I2.add()
{
console.write("this is del method");
}
}

//main()
{
I1 i1=new sample();
i1.add();
I2 i2=new sample();
i2.add();
}
}

here we can achieve multiple inheritence and we can avoid 
the naming conficts..hope it will be usefull ........

The above one is a right answer but the reader who reads it 
for referance plz Note line :
                
        I1 i1=new sample();
        i1.add();

This might confusing but It means that We have created 
object of I1 interface class but with sample as a assigned 
object which is valic in this case.
Now call of i1.add() will call the method of interface I1 
which points to or defined in Sample class 
This will more clearer if you will append two or three more 
simple methods like subtract() and try to call it as above 
one which actually a part of Mostly used Multiple 
Inheritance funda.
personally speaking it will benefitial to you if try 
yourself
Hope readers like tips

hiii friends,

c# not support multiple inheritance its only support single level inheritance and in multiple inheritance support through interface

Through Interfaces multiple inherirance is possible.But 
single inheritance is possible with inheritance only.
