SemanticModel.LookupSymbols Method

Definition

Namespace:

Microsoft.CodeAnalysis

Assembly:

Microsoft.CodeAnalysis.dll

Package:

Microsoft.CodeAnalysis.Common v4.9.2

Source:

SemanticModel.cs

Gets the available named symbols in the context of the specified location and optional container. Only symbols that are accessible and visible from the given location are returned.

public System.Collections.Immutable.ImmutableArray<Microsoft.CodeAnalysis.ISymbol> LookupSymbols (int position, Microsoft.CodeAnalysis.INamespaceOrTypeSymbol? container = default, string? name = default, bool includeReducedExtensionMethods = false);

member this.LookupSymbols : int * Microsoft.CodeAnalysis.INamespaceOrTypeSymbol * string * bool -> System.Collections.Immutable.ImmutableArray<Microsoft.CodeAnalysis.ISymbol>

Public Function LookupSymbols (position As Integer, Optional container As INamespaceOrTypeSymbol = Nothing, Optional name As String = Nothing, Optional includeReducedExtensionMethods As Boolean = false) As ImmutableArray(Of ISymbol)

Parameters

position

Int32

The character position for determining the enclosing declaration scope and accessibility.

container

INamespaceOrTypeSymbol

The container to search for symbols within. If null then the enclosing declaration scope around position is used.

name

String

The name of the symbol to find. If null is specified then symbols with any names are returned.

includeReducedExtensionMethods

Boolean

Consider (reduced) extension methods.

Returns

ImmutableArray<ISymbol>

A list of symbols that were found. If no symbols were found, an empty list is returned.

Remarks

The "position" is used to determine what variables are visible and accessible. Even if "container" is specified, the "position" location is significant for determining which members of "containing" are accessible.

Labels are not considered (see LookupLabels(Int32, String)).

Non-reduced extension methods are considered regardless of the value of includeReducedExtensionMethods.
