IDataServiceStreamProvider.ResolveType Method

Returns a namespace-qualified type name that represents the type that the data service runtime must create for the media link entry that is associated with the data stream for the media resource that is being inserted.

Namespace:  System.Data.Services.Providers
Assembly:  System.Data.Services (in System.Data.Services.dll)

string ResolveType(
	string entitySetName,
	DataServiceOperationContext operationContext
)

Parameters

entitySetName
Type: System.String
Fully-qualified entity set name.
operationContext
Type: System.Data.Services.DataServiceOperationContext
The DataServiceOperationContext instance that is used by the data service to process the request.

Return Value

Type: System.String
A namespace-qualified type name.

The ResolveType method is called by the data service when a new entity that is a media link entry is being created together with its media resource. An implementer of this method must inspect the request headers in operationContext and return the namespace qualified type name that represents the type that the data service runtime must instantiate to create the media link entry that is associated with the new media resource. The string that represents this type name is passed to the CreateResource method to create the media link entry.

When you implement the GetWriteStream method, you should raise the following exceptions as indicated:

Exception type

Condition

ArgumentNullException

When operationContext is null.

DataServiceException

When an entity type name cannot be resolved based on the operationContext.
