Validate Strong Name of Running Assembly

Question

Is it possible for one to check the strong name of a .NET application that is already currently running separately from your own running applications process?

---

EDIT: For clarification, a solution that does not require a hard coded path to the executing assembly would be the most ideal solution.

---

EDIT #2: Is there any way to do this without using reflection?

Answer 1

If by "strong name" you mean the exe name:

using System.Diagnostics;

if (Process.GetProcessesByName("whatever.exe").Length > 0)
{
     //do something

}

Answer 2

Does this give you what you are looking for?

    Process[] processlist = Process.GetProcesses();

    foreach(Process theprocess in processlist)
    {
        string strongName = "N/A";
        try
        {
            strongName = Assembly.ReflectionOnlyLoadFrom(theprocess.MainModule.FileName).FullName;
        }
        catch
        {
            // System process?
        }
        Console.WriteLine("Process: {0} ID: {1} Strong Name: {2}", theprocess.ProcessName, theprocess.Id, strongName);
    }

Answer 3

That should work:

public static bool IsStrongNamed(string assemblyPath)
{
    try
    {
        Assembly a = Assembly.ReflectionOnlyLoadFrom(assemblyPath);
        byte[] publicKey = a.GetName().GetPublicKey();

        return publicKey.Length > 0;
    }
    catch { return false; }
}

public static bool GetStrongName(string assemblyPath)
{
    try
    {
        Assembly a = Assembly.ReflectionOnlyLoadFrom(assemblyPath);

        return a.FullName;
    }
    catch { return string.Empty; }
}

Answer 4

Without reflection:

If you know the process, you know the filename. If you know the filename, you can process the PE headers to find the strong name signature.

Answer 5

Hmm I think the solution to Your problem is the AssemblyName class.
First

Process.GetProcesses().Where(p => p.ProcessName = nameUWant); //maybe single or default?

then with each process take Process.Modules to get dlls or exes loaded by this process. After You obtain the name You want. (the module has name property). Then use

AssemblyName.GetAssemblyName().GetPublicKeyToken() != null

This should work. hope it helps
