Enumerating Running Processes

To illustrate the process of manipulating Process types (pardon the redundancy), assume you have

a C# Console Application named ProcessManipulator that defines the following static helper

method within the Program class (be sure you import the System.Diagnostics namespace):

static void ListAllRunningProcesses()

{

// Get all the processes on the local machine.

Process[] runningProcs = Process.GetProcesses(".");

// Print out PID and name of each process.

foreach(Process p in runningProcs)

{

string info = string.Format("-> PID: {0}\tName: {1}",

p.Id, p.ProcessName);

Console.WriteLine(info);

}

Console.WriteLine("************************************\n");

}

Notice how the static Process.GetProcesses() method returns an array of Process types that

represent the running processes on the target machine (the dot notation shown here represents the

local computer). Once you have obtained the array of Process types, you are able to trigger any of

the members seen in Table 17-2. Here, you are simply displaying the PID and the name of each

process. Assuming the Main() method has been updated to call ListAllRunningProcesses(), you

will see something like the output shown in Figure 17-3.
