Question

In c#, I am using the following code:

Process[] processes = Process.GetProcesses("firefox.exe");
Console.WriteLine(processes.Length);

Which results in:

InvalidOperationException: Couldn’t connect to remote machine.

Notes:

• OS: Windows 7, 64-bit
• I am not attempting to connect to a remote machine.
• The Remote Registry service is set to Auto and is started

Any thoughts as to why am I getting this error and how can I fix it?

According to http://msdn.microsoft.com/en-us/library/x8b2hzk8.aspx this call tries to connect to a computer names “firefox.exe” and retrieve the processes from there hence the exception.

EDIT:

Assuming you want to find all “firefox.exe” processes on the local machine you could

List<Process> ListOfFireFox = new List<Preocess>();
foreach (P in Process.GetProcesses())
{
    if ( P.ProcessName.ToLower() == "firefox.exe" )
         ListOfFireFox.Add (P);
};

Console.WriteLine(ListOfFireFox.Count);
