Most of the assembly-wide attributes (which are usually specified in AssemblyInfo.cs) are available using Assembly.GetCustomAttributes. For instance, to get the assembly title, you could use code such as:

Assembly asm = this.GetType().Assembly;
object[] attrs = asm.GetCustomAttributes(typeof(AssemblyTitleAttribute), false));
if (attrs.Length == 1)
{
    Console.WriteLine(((AssemblyTitleAttribute)attrs[0]).Title);
}

 

Note, the AssemblyVersionAttribute ends up as just part of the assembly name, which can be retrieved with the Assembly.GetName method. The version can be retrieved from the name with the Version property. For example:

Assembly asm = this.GetType().Assembly;
Console.WriteLine(asm.GetName().Version);
