Answer / aditya

Nullable type is introduced in .NET 2.0. Before 2.0 it was
not possible to assign null to value types.
This was possible with the introduction of Generics in 2.0
and the it would be something like this...

System.Nullable<int> x = new System.Nullable<int>;

or

int? salary = null (new type modifier in 2.0)

Answer / yogesh

Cannot convert null to a value type.
So it is not possible to assign null to value type.

Value types include:
All numeric data types
Boolean, Char, and Date
All structures, even if their members are reference types
Enumerations, since their underlying type is always
Byte, Short, Integer, or Long

Reference types include:
String
All arrays, even if their elements are value types
Class types, such as Form
Delegates

Answer / ahmad al mursalin

Yes, In C# 2.0 there is introduced one new type called
nullable types. through this we can assign null value in any
value type like...
bool?flag=null;
but before evaluate this value we should check flag value like..
if(!flag.HasValue)
{
flag=true;
}
after that we have to cast bool value to bool like..
if((bool)flag)
{
//write your code.
}

Answer / narayana

Yes We can Assign
A nullable int can store null. Nullable types in the C#
language can be constructed by specifying the question mark
after a value type in a declarator statement. The nullable
int can be specified with the syntax "int?".

Example:
int a=b=10;
int? c= null;
c=a+b
