)

Parameters

contextType
Type: System.DirectoryServices.AccountManagement.ContextType

A ContextType enumeration value specifying the type of store for the principal context.

name
Type: System.String

The name of the domain or server for Domain context types, the machine name for Machine context types, or the name of the server and port hosting the ApplicationDirectory instance.

If the name is null for a Domain context type this context is a domain controller for the domain of the user principal under which the thread is running. If the name is null for a Machine context type, this is the local machine name. This parameter cannot be null for ApplicationDirectory context types.

container
Type: System.String

The container on the store to use as the root of the context. All queries are performed under this root, and all inserts are performed into this container.

For Domain and ApplicationDirectory context types, this parameter is the distinguished name of a container object.

For Machine context types, this parameter must be set to null.

userName
Type: System.String

The username used to connect to the store. If the username and password parameters are both null, the default credentials of the current principal are used. Otherwise, both username and password must be non-null, and the credentials they specify are used to connect to the store.

password
Type: System.String

The password used to connect to the store. If the username and password parameters are both null, the default credentials of the current principal are used. Otherwise, both username and password must be non-null, and the credentials they specify are used to connect to the store.

ExceptionCondition
ArgumentException

The username and password parameters must either be null or contain a value.

A container cannot be specified when the Machine context type is specified in the contextType parameter.

A name or container must be specified when ApplicationDirectory is specified in the contextType parameter.

InvalidEnumArgumentException

The contextType parameter does not contain a valid ContextType enumeration value.

The InvalidOperationException may be thrown in subsequent directory operations calls that connect to the server if the container specified for a Domain principal context is not a valid container. A container is defined as an object whose schema class has the principal classes, either user, group, or computer, in its possibleInferiors attribute.
