Process.MachineName Property

Definition

Namespace:

System.Diagnostics

Assembly:

System.Diagnostics.Process.dll

Source:

Process.cs

Gets the name of the computer the associated process is running on.

public:
 property System::String ^ MachineName { System::String ^ get(); };

public string MachineName { get; }

member this.MachineName : string

Public ReadOnly Property MachineName As String

Property Value

String

The name of the computer that the associated process is running on.

Exceptions

InvalidOperationException

There is no process associated with this Process object.

Examples

To use the following example you must first start at least one instance of Notepad on a remote computer. The example requests the name of the remote computer on which Notepad is running, and then displays the respective ProcessName, Id, and MachineName properties for each instance.

using System.Diagnostics;

    {
        Console.WriteLine("Create notepad processes on remote computer");

        string remoteMachineName = Console.ReadLine();

        if (remoteMachineName == null)
        {
            // Prepend a new line to prevent it from being on the same line as the prompt.
            Console.WriteLine(Environment.NewLine + "You have to enter a remote computer name.");

        {
            // Get all notepad processess into Process array.
            Process[] myProcesses = Process.GetProcessesByName("notepad", remoteMachineName);

Remarks

You can view statistical data and process information for processes running on remote computers but you cannot call Start, CloseMainWindow, or Kill on remote computers.

Note

When the associated process is executing on the local machine, this property returns a period (".") for the machine name. You should use the Environment.MachineName property to get the correct machine name.
