How to fix a .NET application?

[LordCoder]

Hello everyone I hope someone can help me.

I'm using Mono.Cecil.dll to edit the name of the Namespaces/Classes/Functions. Everything is alright but when I save it and then I run it it shows an error of Windows that leaves to work.

 

Here is my code:

Dim assembly As AssemblyDefinition

assembly = AssemblyFactory.GetAssembly("The path of the .NET file")

Dim definition3 As TypeDefinition

For Each definition3 In assembly.MainModule.Types

  EditType(definition3)

Next

AssemblyFactory.SaveAssembly(assembly, Application.StartupPath & "\App1.exe")

And for the "EditType" function:

    Private Sub EditType(ByVal type As TypeDefinition)

        If ((((type.Name <> "<Module>") AndAlso Not type.IsRuntimeSpecialName) AndAlso (Not type.IsSpecialName AndAlso Not type.Name.Contains("Resources"))) AndAlso ((Not type.Name.StartsWith("<") AndAlso Not type.Name.Contains("__")))) Then

            Dim fullName As String = type.FullName

            type.Name = "Here random strings"

            Dim definition2 As ModuleDefinition

            For Each definition2 In assembly.Modules

                Dim reference As TypeReference

                For Each reference In definition2.TypeReferences

                    If (reference.FullName = fullName) Then

                        reference.Name = type.Name

                    End If

                Next

            Next

            End If

    End Sub

The code is well but I searched to fix this problem of the "App leave to work" message but I didn't find nothing

 

Thanks a lot!

Why don't you use

- AssemblyDefinition assembly = AssemblyDefinition.ReadAssembly(@"c:\full\path\to\original.exe");

- assembly.Write(@"c:\full\path\to\edited.exe"); ?

And if you get an error, why don't you debug it rather than compiling then running ?

@mArTi This option it's for a newer version of Mono.Cecil.dll and i'm using an old version because I need some utilities from it.

Thanks for replying!
