Definition

Namespace:

Microsoft.VisualStudio.TextManager.Interop

Assembly:

Microsoft.VisualStudio.Interop.dll

Package:

Microsoft.VisualStudio.Interop v17.13.40008

Determines the span of the current language block.

C++/CX

public interface class IVsLanguageBlock

Attributes

GuidAttribute InterfaceTypeAttribute

Remarks

Implement this interface to provide custom information about a language block for your language. The definition of a language block is particular to each programming language. For example, a language block in Visual Basic extends from the Sub command to the End Sub command as shown in the following example:

Private Sub SubroutineName()

End Sub

Language block information is typically used with the Find command to confine a search to a single function or method. This interface is also used to select an entire method when the user double-clicks in the selection margin.

Notes to Implementers

Implement this interface on the language service object to provide information about a language block within the core text editor.

Notes to Callers

Obtain this interface by asking the language service for it through the QueryService method. For example:

C#

    public IVsLanguageBlock GetTextOps(Microsoft.VisualStudio.OLE.Interop.IServiceProvider provider,  
Guid languageServiceGuid)  
    {  
        IVsLanguageBlock languageBlock = null;  
        languageBlock = provider.QueryService(languageServiceGuid,  
                                              typeof(IVsLanguageBlock).GUID)  
                                as IVsLanguageBlock;  
        return languageBlock;  
    }  

Methods

GetCurrentBlock(IVsTextLines, Int32, Int32, TextSpan[], String, Int32)
