Hello ,

I am a beginner in C# and have studied the video's from Bob tabor on www.learningvisualstudio.net. But now I found a book about visual c# 2005 express edition from Patrice Pelland. But there is a task about to make a webbrowser.
He give us some code about the Assembly.
Here is the code

public string AssemblyTitle
    {
    get
        {
        // Get all Title attributes on this assembly
        object[] attributes = Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(AssemblyTitleAttribute), false);
        // If there is at least one Title attribute
        if (attributes.Length > 0)
            {
            // Select the first one
            AssemblyTitleAttribute titleAttribute = (AssemblyTitleAttribute)attributes[0];
            // If it is not an empty string, return it
            if (titleAttribute.Title != "")
                return titleAttribute.Title;
            }
        // If there was no Title attribute, or if the Title attribute was the empty string, return the .exe name
        return System.IO.Path.GetFileNameWithoutExtension(Assembly.GetExecutingAssembly().CodeBase);
        }
    }
public string AssemblyVersion
    {
    get
        {
        return Assembly.GetExecutingAssembly().GetName().Version.ToString();
        }
    }
public string AssemblyDescription
    {
    get
        {
        // Get all Description attributes on this assembly
        object[] attributes = Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(AssemblyDescriptionAttribute), false);
        // If there aren't any Description attributes, return an empty string
        if (attributes.Length == 0)
            return "";
        // If there is a Description attribute, return its value
        return ((AssemblyDescriptionAttribute)attributes[0]).Description;
        }
    }
public string AssemblyProduct
    {
    get
        {
        // Get all Product attributes on this assembly
        object[] attributes = Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(AssemblyProductAttribute), false);
        // If there aren't any Product attributes, return an empty string
        if (attributes.Length == 0)
            return "";
        // If there is a Product attribute, return its value
        return ((AssemblyProductAttribute)attributes[0]).Product;
        }
    }
public string AssemblyCopyright
    {
    get
        {
        // Get all Copyright attributes on this assembly
        object[] attributes = Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(AssemblyCopyrightAttribute), false);
        // If there aren't any Copyright attributes, return an empty string
        if (attributes.Length == 0)
            return "";
        // If there is a Copyright attribute, return its value
        return ((AssemblyCopyrightAttribute)attributes[0]).Copyright;
        }
    }
public string AssemblyCompany
    {
    get
        {
        // Get all Company attributes on this assembly
        object[] attributes = Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(AssemblyCompanyAttribute), false);
        // If there aren't any Company attributes, return an empty string
        if (attributes.Length == 0)
            return "";
        // If there is a Company attribute, return its value
        return ((AssemblyCompanyAttribute)attributes[0]).Company;
        }
    }

He didn't give us a explanation why en when to use this code. Can someone give advice how to search for information. I was searching on google but it is so many information that I am in a lost. How did you guys learn the c# code. I know everything about the basic stuff. Classes (OOP) , methods and etc.. I am not someone that want to copy and paste code, because I want to learn something.

regards,

Samir
