DbProviderSpecificTypePropertyAttribute Class

Definition

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

[System.Serializable]

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
