    serviceGuid As Guid _

'使用
Dim instance As ServiceProvider

public function GetService(
    serviceGuid : Guid
) : Object

Parameters

serviceGuid
Type: System.Guid

The GUID of a service.

Return Value

Type: System.Object

The service with the specified service GUID, or a null reference (Nothing in Visual Basic) if no service is found.

Remarks

This method uses the information specified by the Services property to map the GUID into a Type value, and then tries to get the service through a call to GetService. If this method is not able to obtain the service, and the parent implements the unmanaged IServiceProvider to which the specified service GUID can be passed, it queries the parent service.
