ConnectionOptions()

Source:

ManagementOptions.cs

Initializes a new instance of the ConnectionOptions class for the connection operation, using default values. This is the parameterless constructor.

public:
 ConnectionOptions();

public ConnectionOptions ();

Public Sub New ()

Examples

The following example connects to a remote computer and displays information about the operating system on the remote computer. A ConnectionOptions is created to connect to the remote computer with default connection options.

using System;
using System.Management;
public class RemoteConnect

    public static void Main()

        // if you plan to connect to the remote
        // computer with a different user name
        // and password than the one you are currently using.
        // This example uses the default values.

        ConnectionOptions options =
            new ConnectionOptions();

        // Make a connection to a remote computer.
        // Replace the "FullComputerName" section of the
        // string "\\\\FullComputerName\\root\\cimv2" with
        // the full computer name or IP address of the
        // remote computer.
