When i try to write process' information to console i get System.ArgumentException and System.ComponentModel.Win32Exception. What causes this? How can i stop having those?
Process processListe = Process.GetProcesses();
for (int i = 0; i < processListe.Count(); i++)
{
try
{
string companyName = processListe[i].MainModule.FileVersionInfo.CompanyName;
string fileVersion = processListe[i].MainModule.FileVersionInfo.FileVersion;
Console.WriteLine(companyName + " " + fileVersion);
}
catch (Exception) { }
}
Errors happen in "string companyName = processListe[i].MainModule.FileVersionInfo.CompanyName;" line.
Error messages:

Lastly i've made an information output of those process which makes me get errors:

The short answer is that you can't get rid of the exceptions. There are a couple of exceptions I see when I run this code that I don't see explicitly called out in the documentation:
