The AdoDotNetObjectIdentifierConverter type exposes the following members.

Constructors

  Name Description
Public method AdoDotNetObjectIdentifierConverter Class constructor. Initializes a new instance of the xx class, providing a DataConnection object to the data source.

Methods

  Name Description
Protected method BuildString Builds a string version of an identifier. (Inherited from DataObjectIdentifierConverter.)
Public method ConvertToArray Converts a formatted string identifier into its equivalent set of identifier parts. (Inherited from DataObjectIdentifierConverter.)
Public method ConvertToString Converts a set of identifier parts into a formatted string identifier based on the specified formatting options. (Inherited from DataObjectIdentifierConverter.)
Public method Equals Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Protected method FormatPart Formats a specified identifier part; where the with Quotes parameter is true, this method calls the QuoteIdentifier method. (Overrides DataObjectIdentifierConverter.FormatPart(String, Object, Boolean).)
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Protected method SplitIntoParts Retrieves the composite identifier separator pattern from the ADO.NET provider's data source information and calls the Split method with this value and the input string. (Overrides DataObjectIdentifierConverter.SplitIntoParts(String, String).)
Public method ToString Returns a string that represents the current object. (Inherited from Object.)
Protected method UnformatPart Calls the UnquoteIdentifier method. (Overrides DataObjectIdentifierConverter.UnformatPart(String, String).)

Remarks

Typically the identifier of some object on a data source consists of some string that is used in commands that get executed. For example, in the SQL statement, SELECT * FROM mytable, the string "mytable" is a unique identifier of an object in the context under which the statement is running.

Typically a data source has some kind of containment mechanism for objects, such as a catalog, schema, or package. This introduces the need for multi-part identifiers, as a single name no longer suffices for uniquely identifying objects. For example, an Oracle server groups different objects under different users, causing the unique identifier of an object to be qualified with a user name.

Since the format of such multi-part identifiers can vary from one data source to another, there has to be a way to convert a given string into its set of parts and vice versa. For this reason, Visual Studio can expose objects in the same groups of containment to a user. This class provides such a mechanism.

Thread Safety

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