ServiceProvider.GetService Method (Type)
Gets type-based services from the unmanaged service provider.
Assembly: Microsoft.VisualStudio.Shell.14.0 (in Microsoft.VisualStudio.Shell.14.0.dll)
Parameters
- serviceType
-
Type:
System.Type
The type of service to retrieve. The GUID of this type is used to obtain the service from the native service provider.
Implements
IServiceProvider.GetService(Type)Managed VSPackages can use GetService to get VSSDK COM interfaces by querying the interop assemblies. For more information, see Interop Namespaces.
To get a specific VSSDK interface:
GetService should be called with a serviceType returned by using that interface as an argument to typeof.
The return value of GetService must be cast to the interface type. The casting is necessary because GetService queries the input type for the GUID of the service that provides it. An IUnknown interface on the class implementing the service is then returned, and must be cast to obtain the desired object. (The object must be supported on the underlying service.)
For example, one could get an IVsUIShell interface with:
myUIShell = myPackage.GetService(System.typeof(IVsUIShell)) as IVsUIShell;

For historical reasons, the IVsTextManager interface that cannot be obtained in this manner. To obtain an IVsTextManager interface, first use VsTextManagerClass (the class implementing the interface) as the argument to typeof, then cast the return value of GetService to IVsTextManager, for instance: IVsTextManager mytext_mgr = myPackage.GetService(System.typeof(VsTextManagerClass)) as IVsTextManager; |
