Syntax

'Declaration

    Inherits SchemaCollectionBase
'Usage
Dim instance As UserDefinedTypeCollection

public sealed class UserDefinedTypeCollection : SchemaCollectionBase

public ref class UserDefinedTypeCollection sealed : public SchemaCollectionBase

[<SealedAttribute>]
type UserDefinedTypeCollection =  
    class
        inherit SchemaCollectionBase
    end

public final class UserDefinedTypeCollection extends SchemaCollectionBase

The UserDefinedTypeCollection type exposes the following members.

Properties

	Name	Description
	Count	Gets the number of objects in the referenced collection. (Inherited from SmoCollectionBase.)
	IsSynchronized	Gets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe. (Inherited from SmoCollectionBase.)
	Item[Int32]	Gets a UserDefinedType object in the collection by index number.
	Item[String]	Gets a UserDefinedType object in the collection by name.
	Item[String, String]	Gets a UserDefinedType object in the collection by name and schema.
	Parent	Gets the Database object that is the parent of the UserDefinedType object.
	SyncRoot	Gets an object that can be used to synchronize access to the collection. (Inherited from SmoCollectionBase.)

Methods

	Name	Description
	Add	Adds a user-defined type to the collection.
	AddExisting	Adds an object to the collection. (Inherited from AbstractCollectionBase.)
	AddImpl	Adds the specified object to this collection (Inherited from SortedListCollectionBase.)
	Contains(String)	Validates whether the parameter collection contains a member with a name equal to the specified string. (Inherited from SchemaCollectionBase.)
	Contains(String, String)	Validates whether the parameter collection contains a member with a name equal to the specified string and with the specified schema. (Inherited from SchemaCollectionBase.)
	CopyTo	Copies the collection objects to a one-dimensional array starting at the specified index value.

	MemberwiseClone	(Inherited from Object.)
	Refresh()	Refreshes the referenced collection. (Inherited from SmoCollectionBase.)
	Refresh(Boolean)	Refreshes the referenced collection with the option to refresh child objects of the referenced collection. (Inherited from SmoCollectionBase.)

Remarks

A UserDefinedTypeCollection object can be used to gain access to a set of alias data types. You can use the Item property to return a specific UserDefinedType object.

Thread Safety

Any public static (Shared in Microsoft Visual Basic) members of this type are safe for multithreaded operations. Any instance members are not guaranteed to be thread safe.
