Remarks
The DbProviderSpecificTypePropertyAttribute is used by a provider writer to designate a provider-specific type parameter property which is not inherited from the DbParameter base class. The SqlDbType property of a SqlParameter is an example of a provider-specific type property not found in DbParameter.
A provider writer can apply DbProviderSpecificTypePropertyAttribute(true) to indicate a provider-specific data type parameter property. This allows for its discovery using reflection, which enables code generation tools, such as those used in Visual Studio, to generate code geared to a specific provider. The IsProviderSpecificTypeProperty property returns true if the property has been set, otherwise false.
Constructors
| DbProviderSpecificTypePropertyAttribute(Boolean) |
Initializes a new instance of the DbProviderSpecificTypePropertyAttribute class. |
Properties
| IsProviderSpecificTypeProperty |
Indicates whether the attributed property is a provider-specific type. |
| TypeId |
When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute) |
Methods
| Equals(Object) |
Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute) |
| GetHashCode() |
Returns the hash code for this instance. (Inherited from Attribute) |
| GetType() |
Gets the Type of the current instance. (Inherited from Object) |
| IsDefaultAttribute() |
When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute) |
| Match(Object) |
When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute) |
| MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
| ToString() |
Returns a string that represents the current object. (Inherited from Object) |
Explicit Interface Implementations
| _Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr) |
Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute) |
| _Attribute.GetTypeInfo(UInt32, UInt32, IntPtr) |
Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute) |
| _Attribute.GetTypeInfoCount(UInt32) |
Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute) |
| _Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr) |
Provides access to properties and methods exposed by an object. (Inherited from Attribute) |
