CLS Attribute in DotNet

Hi Guys,

The when i see the microsoft forums and other forums sites, many guys ask about CLSCompliant attribute in the class file or assembly. i have idea about that , and i will post here. It's not complicated, but have some conditions and etc...

The conditions means, CLS-Command Language Specification(.NET).When i can say .net is great framework for all guys.because of it's multi language supporting such as VB.NET,C++.NET,C#.NET,J# and etc....Somebody can ask how can support a framework to multi language? answer is that is th .NET FRAMEWORK.

Come to point..
so when we try a code in any language with .net Framework, we must follow few rules , when we will apply CLSCompliant attribute.

a::The methods are not same. it;s we have one method call "GetUsers()", and we don't have a method like "GETUSERS()".

b::Only properties and methods may be overloaded, Operators should not be overloaded.

c::We must avoid unsignned datatype within the class file

d::Publicly exposed members cannot start with an underscore ( _ )

e::Unsafe types like pointers should not be used with public members. However they can be used with private members.

f::Operators can't be overloaded

g::Unsigned types should not be part of the public interface of the class.


we can apply CLSCompliant to assemblies, modules, types, and members.

Example::A(apply to class)
[CLSCompliant(true)]
public class Smp
{

}

Example::B(apply to assembly
using System;
[assembly:CLSCompliant(true)]

Con....

If you develop applications that conform to the CLS, your program will be interoperable with a wide range of .Net supported programming languages. Therefore, your application is likely to have a wider customer base than a non-CLS-compliant version of your application. You can make sure that the C# programs you develop are CLS compliant by using the CLSCompliantAttribute, which will cause the compiler to raise errors if the program is not CLS compliant.
