Answer 1

Read you source files:

List<string> sources = new List<string>();

foreach (string file in Directory.GetFiles(path, "*.cs"))            
    sources.Add(File.ReadAllText(file));

Create compiler parameters:

CompilerParameters parameters = new CompilerParameters();
parameters.GenerateExecutable = false;
parameters.GenerateInMemory = true;

Add references to required libraries:

parameters.ReferencedAssemblies.Add("mscorlib.dll"); 
parameters.ReferencedAssemblies.Add("System.dll"); 
// etc

Compile your source to in-memory assembly:

var provider = new CSharpCodeProvider();
var results = provider.CompileAssemblyFromSource(parameters, sources.ToArray());

Verify compilation successful:

if (results.Errors.HasErrors)
{
    // display results.Errors
}

And use Reflection to read compiled types info:

var assembly = results.CompiledAssembly;
var types = assembly.GetTypes();

foreach (Type type in types)
{
    string name = type.Name;
    var properties = type.GetProperties(); // public properties
    // etc
}
