DbProviderSpecificTypePropertyAttribute Class

DbProviderSpecificTypePropertyAttribute Class


Identifies which provider-specific property in the strongly typed parameter classes is to be used when setting a provider-specific type.

Namespace:   System.Data.Common
Assembly:  System.Data (in System.Data.dll)


[AttributeUsageAttribute(AttributeTargets.Property, AllowMultiple = false, 
	Inherited = true)]
public sealed class DbProviderSpecificTypePropertyAttribute : Attribute


Initializes a new instance of a DbProviderSpecificTypePropertyAttribute class.


Indicates whether the attributed property is a provider-specific type.


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


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.)


Returns the hash code for this instance.(Inherited from Attribute.)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_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.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_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.
