用法
Dim instance As IVsExpansionManager
[GuidAttribute("CA09E5EA-FEE7-4B52-AFE6-8EA2EC53F681")]
[InterfaceTypeAttribute()]
public interface IVsExpansionManager
[GuidAttribute(L"CA09E5EA-FEE7-4B52-AFE6-8EA2EC53F681")]
[InterfaceTypeAttribute()]
public interface class IVsExpansionManager
[<GuidAttribute("CA09E5EA-FEE7-4B52-AFE6-8EA2EC53F681")>]
[<InterfaceTypeAttribute()>]
type IVsExpansionManager = interface end
public interface IVsExpansionManager
Remarks
The expansion manager is a helper interface that provides access to information about code snippets. This interface can also present a list of snippets to be inserted at a particular place in a document.
Notes to Implementers
This interface is implemented by Visual Studio.
Notes to Callers
This interface is obtained by calling the GetExpansionManager method in the IVsTextManager2 interface.
Examples
This example shows how to retrieve the IVsExpansionManager interface given a service provider.
using System;
using System.Runtime.InteropServices;
using Microsoft.VisualStudio;
using Microsoft.VisualStudio.TextManager.Interop;
using IOleServiceProvider = Microsoft.VisualStudio.OLE.Interop.IServiceProvider;
namespace MyPackage
{
public class MyClass
{
public object GetService(IOleServiceProvider serviceProvider,
Guid serviceGuid,
Guid interfaceGuid)
{
IntPtr pUnknown = IntPtr.Zero;
object unknown = null;
int hr = serviceProvider.QueryService(ref serviceGuid,
ref interfaceGuid,
out pUnknown);
if (ErrorHandler.Succeeded(hr))
{
unknown = Marshal.GetObjectForIUnknown(pUnknown);
}
return unknown;
}
private IVsExpansionManager GetExpansionManager(IOleServiceProvider serviceProvider)
{
IVsExpansionManager expansionManager = null;
IVsTextManager textManager;
textmanager = (IVsTextManager)this.GetService(serviceProvider,
typeof(SVsTextManager).GUID,
typeof(IVsTextManager).GUID);
if (textManager != null)
{
IVsTextManager2 textManager2 = (IVsTextManager2)textManager;
if (textManager2 != null)
{
textManager2.GetExpansionManager(out expansionManager);
}
}
}
return expansionManager;
}
}
