Finding a class in an assembly?

My program compiles script files written in VB.NET at run-time into an assembly in memory using the built-in compiler stuff. Now, let's say my script has this in it:

VB Code:

Namespace Testing
    Public Class Abc
        Public Sub TryMe()
            System.Windows.Forms.MessageBox.Show("Hello World")
        End Sub
    End Class
End Namespace

Well, my program will take this script and compile it at run-time into an assembly in memory.

Is there a way to get a list of the namespaces/classes/etc. contained within the assembly, or search through it for a class with a certain name and return its information?

I'm pretty new to assembly stuff and compiling dynamic code at run-time, so I'm not really sure how to do much yet. Any help would be greatly appreciated.

Thanks in advance,
Satch

Maybe you can do something like this.....

Code:

---

Dim asm As System.Reflection.Assembly
asm = System.Reflection.Assembly.LoadFrom("c:\asm.dll")
Dim ty As Type
For Each ty In asm.GetTypes
    MsgBox(ty.FullName)
Next

---

I'm not sure how to get a proper reference to the class in your case, if LoadFrom does not work, try Load or any of the other commands.

of course u can..do a search by the forum and u'll c that i made the same question a while ago..

and by what u say i see that u used the system.reflection.emit ... i am very interested in that but where can i find info about how to use it? tks

Thanks for the responses :)

PT, I found the post and can't wait to get home to try it out. As for the System.Reflection.Emit stuff, I'm not sure if its the same as what I'm doing. I use the Microsoft.VisualBasic.VBCodeProvider and the compiler in System.CodeDOM (can't remember the full name at the moment.) Either way, it'll compile VB.NET code. I'll post a link to it when I get home where I have access to my project's code.

This compiles the compile.vb file in the application's directory and outputs it into assembly.dll and loads it into the memory.

VB Code:

Dim myVBCodeProvider As Microsoft.VisualBasic.VBCodeProvider
Dim myCodeCompiler As CodeDom.Compiler.ICodeCompiler
Dim myCompilerParameters As CodeDom.Compiler.CompilerParameters
Dim myCompilerResults As CodeDom.Compiler.CompilerResults
Dim i As Long
 
myCompilerParameters = New CodeDom.Compiler.CompilerParameters()
myCompilerParameters.GenerateInMemory = False
myCompilerParameters.GenerateExecutable = False
myCompilerParameters.OutputAssembly = Application.StartupPath + "\assembly.dll"
 
myVBCodeProvider = New Microsoft.VisualBasic.VBCodeProvider()
 
Dim asm As [Assembly]
 
For Each asm In AppDomain.CurrentDomain.GetAssemblies
      myCompilerParameters.ReferencedAssemblies.Add(asm.Location)
Next
 
myCodeCompiler = myVBCodeProvider.CreateCompiler()
myCompilerResults = myCodeCompiler.CompileAssemblyFromFile(myCompilerParameters, Application.StartupPath + "\compile.vb")
 
If myCompilerResults.Errors.HasErrors Then
      For i = 1 To myCompilerResults.Errors.Count
            frmMain.DefInstance.lstStatus.Items.Add("Error: " + myCompilerResults.Errors.Item(i - 1).ToString())
            Application.DoEvents()
      Next
      Exit Sub
End If
 
Compiler_Assembly = myCompilerResults.CompiledAssembly

ahh tks...but im in C#...and looks like no one has examples about using system.reflection.emit :( :(
