what is the diference between casting and converting?..

Answer / kiran vaidya

When you use Convert class, you have some predefined types
which are defined by .Net framework such as Convert.ToInt32
or Convert.ToString and so on. That means you can convert
whatever you want to only system defined types.

while in casting, you can have your own choices to convert
data. i.e. user defined types.

for eg. you have a class called Employee and you want to
convert some object to Employee, then the best way to do
this is casting.

Answer / praveen

The Convert.ToInt32(String, IFormatProvider) underneath
calls the Int32.Parse. So the only difference is that if a
null string is passed to Convert it returns 0, whereas
Int32.Parse throws an ArgumentNullException.

It is really a matter of choice whichever you use.

Also have a look at the new .NET 2.0 method Int32.TryParse,
which attempts to convert a string to an int without
throwing an exception.
