ILocalSymbol Interface

Definition

Represents a local variable in method body.

public interface class ILocalSymbol : IEquatable<Microsoft::CodeAnalysis::ISymbol ^>, Microsoft::CodeAnalysis::ISymbol
public interface ILocalSymbol : IEquatable<Microsoft.CodeAnalysis.ISymbol>, Microsoft.CodeAnalysis.ISymbol
type ILocalSymbol = interface
    interface ISymbol
    interface IEquatable<ISymbol>
Public Interface ILocalSymbol
Implements IEquatable(Of ISymbol), ISymbol

Remarks

This interface is reserved for implementation by its associated APIs. We reserve the right to change it in the future.

Properties

CanBeReferencedByName

Returns true if this symbol can be referenced by its name in code.

(Inherited from ISymbol)
ConstantValue

Gets the constant value of this local variable.

ContainingAssembly

Gets the IAssemblySymbol for the containing assembly. Returns null if the symbol is shared across multiple assemblies.

(Inherited from ISymbol)
ContainingModule

Gets the IModuleSymbol for the containing module. Returns null if the symbol is shared across multiple modules.

(Inherited from ISymbol)
ContainingNamespace

Gets the INamespaceSymbol for the nearest enclosing namespace. Returns null if the symbol isn't contained in a namespace.

(Inherited from ISymbol)
ContainingSymbol

Gets the ISymbol for the immediately containing symbol.

(Inherited from ISymbol)
ContainingType

Gets the INamedTypeSymbol for the containing type. Returns null if the symbol is not contained within a type.

(Inherited from ISymbol)
DeclaredAccessibility

Gets a Accessibility indicating the declared accessibility for the symbol. Returns NotApplicable if no accessibility is declared.

(Inherited from ISymbol)
DeclaringSyntaxReferences

Get the syntax node(s) where this symbol was declared in source. Some symbols (for example, partial classes) may be defined in more than one location. This property should return one or more syntax nodes only if the symbol was declared in source code and also was not implicitly declared (see the IsImplicitlyDeclared property).

Note that for namespace symbol, the declaring syntax might be declaring a nested namespace. For example, the declaring syntax node for N1 in "namespace N1.N2 {...}" is the entire NamespaceDeclarationSyntax for N1.N2. For the global namespace, the declaring syntax will be the CompilationUnitSyntax.

(Inherited from ISymbol)
HasConstantValue

Returns false if the local variable wasn't declared as "const", or constant value was omitted or erroneous. True otherwise.

HasUnsupportedMetadata

Indicates that this symbol uses metadata that cannot be supported by the language.

Examples include:

  • Pointer types in VB
  • ByRef return type
  • Required custom modifiers

This is distinguished from, for example, references to metadata symbols defined in assemblies that weren't referenced. Symbols where this returns true can never be used successfully, and thus should never appear in any IDE feature.

This is set for metadata symbols, as follows:

  • Type - if a type is unsupported (for example, a pointer type)
  • Method - parameter or return type is unsupported
  • Field - type is unsupported
  • Event - type is unsupported
  • Property - type is unsupported
  • Parameter - type is unsupported

(Inherited from ISymbol)
IsAbstract

Gets a value indicating whether the symbol is abstract.

(Inherited from ISymbol)
IsConst

Returns true if this local variable was declared as "const" (i.e. is a constant declaration). Also returns true for an enum member.

IsDefinition

Gets a value indicating whether the symbol is the original definition. Returns false if the symbol is derived from another symbol, by type substitution for instance.

(Inherited from ISymbol)
IsExtern

Gets a value indicating whether the symbol is defined externally.

(Inherited from ISymbol)
IsFixed

Returns true if the local variable is declared with fixed-pointer-initializer (in unsafe context).

IsForEach

Returns true if this local variable is declared as iteration variable

IsFunctionValue

Returns true if this local variable is function return variable whose name is the function's name, whose type is the return type of the function and whose initial value is the default of its type.

IsImplicitlyDeclared

Returns true if this symbol was automatically created by the compiler, and does not have an explicit corresponding source code declaration.

(Inherited from ISymbol)
IsOverride

Gets a value indicating whether the symbol is an override of a base class symbol.

(Inherited from ISymbol)
IsRef

Returns true if this local is a ref local or a ref readonly local. Use RefKind to get more detailed information.

IsSealed

Gets a value indicating whether the symbol is sealed.

(Inherited from ISymbol)
IsStatic

Gets a value indicating whether the symbol is static.

(Inherited from ISymbol)
IsUsing

Returns true if the local variable is declared in resource-acquisition of a 'using statement'; otherwise false

IsVirtual

Gets a value indicating whether the symbol is virtual.

(Inherited from ISymbol)
Kind

Gets the SymbolKind indicating what kind of symbol it is.

(Inherited from ISymbol)
Language

Gets the source language ("C#" or "Visual Basic").

(Inherited from ISymbol)
Locations

Gets the locations where the symbol was originally defined, either in source or metadata. Some symbols (for example, partial classes) may be defined in more than one location.

(Inherited from ISymbol)
MetadataName

Gets the name of a symbol as it appears in metadata. Most of the time, this is the same as the Name property, with the following exceptions:

  1. The metadata name of generic types includes the "`1", "`2" etc. suffix that indicates the number of type parameters (it does not include, however, names of containing types or namespaces).
  2. The metadata name of explicit interface names have spaces removed, compared to the name property.
  3. The length of names is limited to not exceed metadata restrictions.
(Inherited from ISymbol)
MetadataToken

Gets the metadata token associated with this symbol, or 0 if the symbol is not loaded from metadata.

(Inherited from ISymbol)
Name

Gets the symbol name. Returns the empty string if unnamed.

(Inherited from ISymbol)
NullableAnnotation

Gets the top-level nullability of this local variable.

OriginalDefinition

Gets the ISymbol for the original definition of the symbol. If this symbol is derived from another symbol, by type substitution for instance, this gets the original symbol, as it was defined in source or metadata.

(Inherited from ISymbol)
RefKind

Whether the variable is a ref or ref readonly local.

ScopedKind

Returns the scoped kind of the local.

Type

Gets the type of this local variable.

Equals(ISymbol, SymbolEqualityComparer)

Determines if this symbol is equal to another, according to the rules of the provided SymbolEqualityComparer

(Inherited from ISymbol)
GetAttributes()
