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)
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)
CustomModifiers	Custom modifiers associated with the parameter type, or an empty array if there are none.
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)
ExplicitDefaultValue	Returns the default value of the parameter.
HasExplicitDefaultValue	Returns true if the parameter specifies a default value to be passed when no value is provided as an argument to a call. The default value can be obtained with the ExplicitDefaultValue property.
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)
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)
IsDiscard	Returns true if the parameter is a discard parameter.
IsExtern	Gets a value indicating whether the symbol is defined externally. (Inherited from ISymbol)
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)
IsOptional	Returns true if the parameter is optional.
IsOverride	Gets a value indicating whether the symbol is an override of a base class symbol. (Inherited from ISymbol)
IsParams	Returns true if the parameter was declared as a parameter array.
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)
IsThis	Returns true if the parameter is the hidden 'this' ('Me' in Visual Basic) parameter.
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: 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). The metadata name of explicit interface names have spaces removed, compared to the name property. 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 the parameter.
Ordinal	Gets the ordinal position of the parameter. The first parameter has ordinal zero. The 'this' parameter ('Me' in Visual Basic) has ordinal -1.
OriginalDefinition	Get the original definition of this symbol. If this symbol is derived from another symbol by (say) type substitution, this gets the original symbol, as it was defined in source or metadata.
RefCustomModifiers	Custom modifiers associated with the ref modifier, or an empty array if there are none.
RefKind	Whether the parameter passed by value or by reference.
ScopedKind	Returns the scoped kind of the parameter.
Type	Gets the type of the parameter.

Equals(ISymbol, SymbolEqualityComparer)	Determines if this symbol is equal to another, according to the rules of the provided SymbolEqualityComparer (Inherited from ISymbol)
