Can I retrieve a list of variable from a .Net assembly?

Hi,

I would like to know if there is a way how to retrieve a list of variable (all modifiers) that make up an assembly.  Basically I am developing a Software Testing automation tool as part of my studies and would need to inspect the contents of the variables that make up the assembly under test.  I have already managed to get the list of properties that make up the interfaces (GUI) of the assembly, the variables used is my next target.

I was thinking maybe the System.Reflection namespace might be helpful, not sure how though.

Hope I was clear in my explanation...feel free to ask in case I was not clear enough.

Any help is appreciated.

Thanks

{
 
public class Tester
{
    public static void Main()
    {
        System.Reflection.Assembly useAssembly = default(System.Reflection.Assembly);
        
        try {
            useAssembly = System.Reflection.Assembly.LoadFile(@"Your assembley");
        }
        catch (System.Exception ex) {
            Console.WriteLine(ex.Message);
            return;
        }
        
        
        Console.WriteLine("Full Name: " + useAssembly.FullName);
        
        Console.WriteLine("Resources");
        foreach (string oneName in useAssembly.GetManifestResourceNames()) {
            Console.WriteLine("   - " + oneName);
        }
        
        Console.WriteLine("Exported Types");
        foreach (System.Type oneType in useAssembly.GetExportedTypes()) {
            Console.WriteLine("   - " + oneType.Name);
        }
        
        Console.WriteLine("Modules");
        foreach (System.Reflection.Module oneModule in useAssembly.GetLoadedModules()) {
            Console.WriteLine("   - " + oneModule.Name);
            foreach (System.Type oneType in oneModule.GetTypes()) {
                Console.WriteLine("     Type: " + oneType.Name);
                foreach (System.Reflection.FieldInfo oneField in oneType.GetFields()) {
                    Console.WriteLine("        Field: " + oneField.ToString());
                }
                
                foreach (System.Reflection.MethodInfo oneMethod in oneType.GetMethods()) {
                    Console.WriteLine("        Method: " + oneMethod.ToString());
                }
            }
        }
        
    }
    
}
 
}

Hi BondinASP,

I think we're close, but it's not exactly what I need.

The scenario is, if for example in the assembly there is a code decalring a variable such as

Public string strName;

I need some code which will return strName as part of the list (together with other variables that are declared within that assembly.  I will need this as I will later need to watch the value changes within these variables.

If the code you provided should allow for this, then I must be doing something wrong.

Looking forward for your reply.

Actually I kept on trying and with a few minor changes and it worked!

This is the key part of your code which gave me what I needed:

BindingFlags getAllFlags = BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.Instance;

foreach (System.Type oneType in oneModule.GetTypes())
{
                            foreach (System.Reflection.FieldInfo oneField in oneType.GetFields(getAllFlags))
                            {
                                dCollect.chBxFieldsToVerify.Items.Add(oneField.ToString());
                            }
}

I added the getAllFlags so that I can retrieve all modifiers, as by default it retrieves only public members.

Thanks very much for your help.

Erm, one other thing...is there any way how I can now watch the values of these retrieved variables while my application is executing this assemly?
