Properties

  Name Description
Protected property ConnectionStringBuilder Gets the underlying ADO.NET connection string builder object for the current connection properties instance.
Public property Count Gets the number of connection properties.
Public property IsComplete Gets a value indicating whether sufficient connection properties have been set for the connection string.
Public property IsExtensible Gets a value indicating whether the DDEX provider connection properties are extensible.
Public property Item Gets or sets a value for a specified property on the DDEX provider. Raises the PropertyChanged() event if the property is set.
Public property Keys Gets all the properties that are part of the data connection string.
Public property Site Gets or sets the object site. (Inherited from DataSiteableObject<T>.)
Public property Values Gets the values of the connection string.

Methods

  Name Description
Public method Add(String, Object) Adds a new property to the current connection properties collection. Raises the PropertyChanged() event.
Public method Add(String, Type, Object) Adds a new property to the current connection properties collection.
Public method Contains Tests whether a specified property name and value pair is a member of the current set of connection properties.
Public method ContainsKey Tests whether the specified property name is a member of the current set of connection properties.
Public method CopyTo Copies the set of connection properties to an array, starting at the specified array index.
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.)
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetSynonyms Retrieves an array list of synonyms for a specified data connection property.
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 OnPropertyChanged Raises the PropertyChanged event when a property changes in the data connection string.
Protected method OnSiteChanged Raises an event if the Site has changed. (Overrides DataSiteableObject<T>.OnSiteChanged(EventArgs).)
Public method Parse Disassembles the components of a connection string into a set of connection properties as set in the current AdoDotNetConnectionProperties class instance. Raises the PropertyChanged() event.
Public method Remove Removes a property from the current connection property collection.
Public method Reset() Resets a connection property to its initial value and raises the PropertyChanged() event.
Public method Reset(String) Removes the given property from the connection string and raises the PropertyChanged() event.
Public method ToDisplayString Retrieves a string representation of the current set of data connection properties that are suitable for on-screen display.
Public method ToSafeString Returns a string representation of the current set of data connection properties, excluding the sensitive properties that should be serialized.
Public method ToString Returns a string representation of the current set of data connection properties. (Overrides Object.ToString().)
Public method TryGetValue Retrieves a value corresponding to the supplied key by calling this method on the .NET Framework connection string builder base class (DbConnectionStringBuilder).

Remarks

It is not expected that a DDEX provider based on ADO.NET will need to customize object enumeration. However, this class is a base class that you can extend in scenarios where added or modified enumeration functionality inside Visual Studio is required.

Most of the public methods on this class are overridden from the base class (IVsDataConnectionProperties) because this implementation does not rely on any of the base class for help with tasks like parsing and building; rather, they typically delegate to the equivalent call on the connection string builder object.

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.
