ConnectionOptions Class


Specifies all settings required to make a WMI connection.

Namespace:   System.Management
Assembly:  System.Management (in System.Management.dll)


Public Class ConnectionOptions
	Inherits ManagementOptions


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

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

Creates a new ConnectionOption.

System_CAPS_pubmethodConnectionOptions(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.


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


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


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.)


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).


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


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


Sets the password for the specified user.


Sets the password for the specified user.


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.)


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


Returns a copy of the object.(Overrides ManagementOptions.Clone().)


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


Creates a shallow copy of the current Object.(Inherited from Object.)


Returns a string that represents the current object.(Inherited from Object.)

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.
