ConnectionOptions

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() 
    {
        // Build an options object for the remote connection
        // 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.
        ManagementScope scope = 
            new ManagementScope(
            "\\\\FullComputerName\\root\\cimv2", options);
        scope.Connect();

        //Query system for Operating System information
        ObjectQuery query = new ObjectQuery(
            "SELECT * FROM Win32_OperatingSystem");
        ManagementObjectSearcher searcher = 
            new ManagementObjectSearcher(scope,query);

        ManagementObjectCollection queryCollection = searcher.Get();
        foreach ( ManagementObject m in queryCollection)
        {
            // Display the remote computer information
            Console.WriteLine("Computer Name : {0}", 
                m["csname"]);
            Console.WriteLine("Windows Directory : {0}", 
                m["WindowsDirectory"]);

                m["Caption"]);

Constructors

ConnectionOptions()

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

ConnectionOptions(String, String, SecureString, String, ImpersonationLevel, AuthenticationLevel, Boolean, ManagementNamedValueCollection, TimeSpan)

Creates a new ConnectionOption.

ConnectionOptions(String, String, String, String, ImpersonationLevel, AuthenticationLevel, Boolean, ManagementNamedValueCollection, TimeSpan)

Initializes a new instance of the ConnectionOptions class to be used for a WMI connection, using the specified values.

Properties

Authentication

Gets or sets the COM authentication level to be used for operations in this connection.

Authority

Gets or sets the authority to be used to authenticate the specified user.

Context

Gets or sets a WMI context object. This is a name-value pairs list to be passed through to a WMI provider that supports context information for customized operation.

(Inherited from ManagementOptions)
EnablePrivileges

Gets or sets a value indicating whether user privileges need to be enabled for the connection operation. This property should only be used when the operation performed requires a certain user privilege to be enabled (for example, a machine restart).

Impersonation

Gets or sets the COM impersonation level to be used for operations in this connection.

Locale

Gets or sets the locale to be used for the connection operation.

Password

Sets the password for the specified user.

SecurePassword

Sets the password for the specified user.

Timeout

Gets or sets the time-out to apply to the operation. Note that for operations that return collections, this time-out applies to the enumeration through the resulting collection, not the operation itself (the ReturnImmediately property is used for the latter). This property is used to indicate that the operation should be performed semi-synchronously.

(Inherited from ManagementOptions)
Username

Gets or sets the user name to be used for the connection operation.

Methods

Clone()

Returns a copy of the object.

Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)
GetHashCode()

Serves as the default hash function.

(Inherited from Object)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
ToString()

Returns a string that represents the current object.

(Inherited from Object)
