Hi,

I have experience in Java and C++ but I am rather new to C# and just
started learning it. I am using Visual C# 2005 Express Edition and I
found that there is a file called "AssemblyInfo.cs", which is something
like I attached below. Would anyone please let me know what is the
purpose of this file? Or are there any equivalent stuff I can imagine
in C++ or Java?

Thanks a lot.
Paul

Hi Paul,

"AssemblyInfo.cs" is a normal C# file (.cs) that is created by VS 2005 when you create a new
project. It's purpose is to encapsulate assembly-level attributes, which provide meta-data for your
compiled assembly.

// C# using directive adds the specified namespace to the file's scope
// so you can code "MethodInfo" in this file, for instance, without having to
// qualify it with a namespace: System.Reflection.MethodInfo.
// (Note: The using statement (different) can be used to ensure
// the disposal of objects that implement the IDisposable interface just
// like you would using try..finally in a method body, but here is a directive).
using System.Reflection;

// AssemblyTitleAttribute (the Attribute part can be left off in C# when the
// class is being used between [] characters) is being used on the Assembly
// as meta-data.
// "assembly:" applies the AssemblyTitleAttribute to the assembly in which
// AssemblyInfo.cs will be compiled.
// The title given for the Assembly is "BasicTest1". This is just meta-data,
// which isn't used by the CLR.
[assembly: AssemblyTitle("BasicTest1")]

The rest of the statements are also just Attributes being used for assembly-level meta-data. Check
out the MSDN docs for each one for more information (don't forget to search for the name used here
and Attribute (e.g., GuidAttribute).

Consider it equivalent to the manifest in a jar file.
