What is Difference Between ToString() vs Convert.ToString() vs (string) cast

There is a simple but important difference between these three.

ToString() raise exception when the object is null

So in the case of object.ToString(), if object is null, it raise NullReferenceException.

Convert.ToString() return string.Empty in case of null object

(string) cast assign the object in case of null

So in case of
MyObject o = (string)NullObject;

But when you use o to access any property, it will raise NullReferenceException.

What is the difference between convert.to.string and .to.string() method?

Convert function handles nulls while i.string() does not it will throw a null reference exception error. (More...)

Value type & reference types difference? Example from .NET. Integer & struct are value types or reference types in .NET?

Most programming languages provide builtin data types, such as integers and floatingpointnumbers, that are copied when they are passed as arguments (that is, they are passed by value). In the .NET Framework, these are called value types. The runtime

supports two kinds of value types:
· Builtin
value types
The .NET Framework defines builtin
value types, such as System.Int32 and
System.Boolean, which correspond and are identical to primitive data types
used by programming languages.
· Userdefined
value types
Your language will provide ways to define your own value types, which derive from System.ValueType. If you want to define a type representing a value that is small, such as a complex number (using two floatingpoint numbers),
you might choose to define it as a value type because you can pass the value type efficiently by value. If the type you are defining would be more efficiently passed by reference, you should define it as a class instead.

Variables of reference types, referred to as objects, store references to the actual data. This following are the reference types:
· class
· interface
· delegate
This following are the builtin
reference types:
· object (More...)
