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

Attributes

Exceptions

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;

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.
