object and Object

[=?Utf-8?B?YzY3NjIyOA==?=]

Hi all,

I am just starting to write some code in C#. One time I accidently used
"object" instead of "Object". The program didn't complain at all and worked
fine.

I am just wondering is there any difference between object and Object in C#?

thanks

Search for a recent thread titled "String or string".

No there is no difference.

Object refers to the real name of the type: System.Object and object is
the language alias for that type.

Thank you both Patrick and Jeff.

Somehow I got an impression from somewhere before(Maybe another programming
language?) that String represent an object data type and string just
represent basic data type. That's why I cannot figure out the difference
between object and Object and I never knew it is an alias in C#.

There is no "primitive" types in C#, all the type keywords in the
language is mapped to a System.XXXX type, for some it's valuetypes like
int, datetime etc, and for others like string it's a reference type,
what most people call an object.

That would be Java. There is no such duplicate data types in C#, instead
it uses boxing whenever a value type needs to be stored as a reference type.

Java does not have simple data types for neither Object nor String.

Hi Betty,

As for the following things you mentioned ,I think that might be specific
to some other programming language rather than .NET/C#.

===============
Somehow I got an impression from somewhere before(Maybe another programming
language?) that String represent an object data type and string just

==============

For .NET framework, all the core FCL is shared in all programming
languages. And for the Object class, the standard .NET class name is
System.Object, and in C#, the language provide the equivalent alias
"object". They are the same. But if you use "System.Object" style, that
will be easier for you to share the type name from other languages.

Sincerely,

Steven Cheng
