public void Delete ()

Comentarios

The Delete method can be called only for a managed property with no mappings; if there are still crawled properties mapped to the managed property, an error occurs with this method.

To prevent this error from occurring, call the DeleteAllMappings method before calling the Delete method.

You should also verify that the managed property can be deleted by checking the value of the DeleteDisallowed property. If this property is true, you cannot delete the managed property from the search schema.

Ejemplo

The following code example deletes a managed property from the search schema. For a more complete sample and explanation of the code, see Procedimiento para eliminar una propiedad administrada.

Prerequisites

Ensure a Shared Service Provider is already created.
