Identifies which provider-specific property in the strongly typed parameter classes is to be used when setting a provider-specific type.
Assembly: System.Data (in System.Data.dll)
| Name | Description | |
|---|---|---|
![]() | DbProviderSpecificTypePropertyAttribute(Boolean) | Initializes a new instance of a DbProviderSpecificTypePropertyAttribute class. |
| Name | Description | |
|---|---|---|
![]() | IsProviderSpecificTypeProperty | Indicates whether the attributed property is a provider-specific type. |
![]() | TypeId |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | This API supports the product infrastructure and is not intended to be used directly from your code. 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() | |
![]() | 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.) |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() | _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.) |
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.
