The PISystems type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
 | Add |
Registers a new PISystem to the list of known systems on the local machine.
|
| Clear |
Unregisters all existing PISystem entries from the list of known
PISystems on the local machine.
|
| Contains(Guid) |
This method determines whether the collection contains a specific item referenced by id.
|
| Contains(String) |
This method determines whether the collection contains a specific item referenced by name.
|
| CopyTo |
Copies the entire collection to a compatible one-dimensional Array,
starting at the specified index of the target array.
|
| DisconnectAll |
Disconnects all PISystems that are currently connected.
|
| Equals |
Determines whether the specified Object is equal to the current object.
(Overrides ObjectEquals(Object).) |
| GetEnumerator |
Returns an enumerator that iterates through the collection.
|
| GetHashCode |
Gets the hash code for this instance of the object which is suitable for use in hashing
algorithms and data structures like a hash table.
(Overrides ObjectGetHashCode.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IndexOf |
Searches for the specified object and returns the zero-based index of the first
occurrence within the entire collection.
|
| Refresh |
Refresh the collection to the list of known systems on the local machine
including disconnected systems.
|
| Refresh(Boolean) |
Refresh the collection to the list of known systems on the local machine with
the option to refresh only connected systems.
|
| Refresh(Boolean, Boolean) |
Refresh the collection to the list of known systems on the local machine with
the option to refresh only connected systems and/or database-level objects.
|
| Remove(Guid) |
Unregisters an existing PISystem with the specified unique identifier.
|
| Remove(String) |
Unregisters an existing PISystem with the specified name.
|
| Remove(PISystem) |
Unregisters the specified PISystem.
|
| RemoveAt |
Unregisters an existing PISystem by removing the entry from the list of known
PISystems on the local machine.
|
| SetApplicationIdentity |
Set the client application identity to identify an application to the servers
to which it connects.
|
| Sort |
Sorts the items in the entire collection using the default comparer.
|
| Sort(IComparerPISystem) |
Sorts the items in the entire collection using the specified comparer.
|
| Sort(Int32, Int32, IComparerPISystem) |
Sorts the items in a range of items in the collection using the specified comparer.
|
| ToString |
Returns a String that represents the current object.
(Overrides ObjectToString.) |
Extension Methods
| Name | Description | |
|---|---|---|
