Hi all
I want to run an exe file in Memorystream
Knowing that I use
.net core 6
chromedriver
When I'm working, I try to use the following code

What I have tried:

C#

if (fileZip.Count()== index)
                      {
                          foreach (var entryexe in fileZip)
                          {
                              if (entryexe.FullName.Contains("exe")|| entryexe.FullName.Contains("dll"))
                              {

                                  byte[] filebin = ms.ToArray();

                                  Assembly assembly = Assembly.Load(filebin);

                                  //MethodInfo method = a.EntryPoint;
                                  //if (method != null)
                                  //{
                                  //    object o = a.
                                  //    // invoke the application starting point
                                  //    method.Invoke(o, null);
                                  //}

                              }
                          }
                      }

This code shows the error

C#

Assembly assembly = Assembly.Load(filebin);

this error

System.BadImageFormatException: 'Bad IL format.'

foreach (var entryexe in fileZip)
{
    if (entryexe.FullName.Contains("exe")|| entryexe.FullName.Contains("dll"))
    {
        byte[] filebin = ms.ToArray();

It looks like you have not extracted the file contents to the memory stream.

Solution 1

You cannot run an executable from anything other than an actual file on disk.
