How can check with C# if Microsoft Outlook is already open?

I have tried looking for the answer to this question... Forgive me if I have overlooked it.

What I am trying to do is automate sending an email. I have everything I want in this code but the code assumes that Outlook is NOT open.

Is there a way for me to test if Outlook is open before it opens another instance of Outlook?

                Microsoft.Win32.RegistryKey key =
           Microsoft.Win32.Registry.LocalMachine.OpenSubKey("Software\\microsoft\\windows\\currentversion\\app paths\\OUTLOOK.EXE");
            string path = (string)key.GetValue("Path");
            if (path != null)
                System.Diagnostics.Process.Start("OUTLOOK.EXE");
            else
                MessageBox.Show("There is no Outlook in this computer!", "SystemError", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);

Since I like clean one-liners, here's what I used:

if (System.Diagnostics.Process.GetProcessesByName("OUTLOOK").Any())
  return true;

using System.Diagnostics; //to make the Process work

Process[ ] processlist = Process.GetProcessesByName 
("OUTLOOK:);
If (processlist.Length>0)
{
//outlook is open
}

You could use the Process class e.g.

Process[] localByName = Process.GetProcessesByName("outlook"); 
// empty array if no outlook process found.
if(localByName.Length > 0)
{ /*do work because outlook is already open*/}
else
{/* start outlook */}

another way could be a wql-query

WqlObjectQuery wqlQuery = new WqlObjectQuery("SELECT * FROM Win32_Process");
ManagementObjectSearcher searcher = new ManagementObjectSearcher(wqlQuery);

foreach (ManagementObject process in searcher.Get()) 
{
    var name = process.GetPropertyValue("Name"); // e.g. outlook.exe
}

Here is one way you can test if Outlook is open, and if it is, you "grab" the current instance. In your catch block, you can open your new instance the way you have listed:

Outlook.Application ol;

try
{
    ol = (Outlook.Application)Marshal.GetActiveObject("Outlook.Application");
}
catch (Exception ex)
{
    // open your new instance
}

int procCount = 0;
Process[] processlist = Process.GetProcessesByName("OUTLOOK");
foreach (Process theprocess in processlist)
{
    procCount++;            
}
 if (procCount > 0)
{
  //outlook is open
}
