Compilation Class

Microsoft.CodeAnalysis.Common v4.7.0

Source:

Compilation.cs

The compilation object is an immutable representation of a single invocation of the compiler. Although immutable, a compilation is also on-demand, and will realize and cache data as necessary. A compilation can produce a new compilation from existing compilation with the application of small deltas. In many cases, it is more efficient than creating a new compilation from scratch, as the new compilation can reuse information from the old compilation.

CommonSyntaxTrees
DirectiveReferences	Unique metadata references specified via #r directive in the source code of this compilation.

ReferencedAssemblyNames	Assembly identities of all assemblies directly referenced by this compilation.
References	All metadata references -- references passed to the compilation constructor as well as references specified via #r directives.
ScriptClass	A symbol representing the implicit Script class. This is null if the class is not defined in the compilation.

GetSemanticModel(SyntaxTree, Boolean)	Gets a new SemanticModel for the specified syntax tree.
GetSpecialType(SpecialType)	Get the symbol for the predefined type from the Cor Library referenced by this compilation.
GetSymbolsWithName(Func<String,Boolean>, SymbolFilter, CancellationToken)	Return source declaration symbols whose name meets given predicate.
GetSymbolsWithName(String, SymbolFilter, CancellationToken)	Return source declaration symbols whose name matches the provided name. This may be faster than GetSymbolsWithName(Func<String,Boolean>, SymbolFilter, CancellationToken) when predicate is just a simple string check. name is case sensitive or not depending on the target language.
GetTypeByMetadataName(String)	Gets the type within the compilation's assembly and all referenced assemblies (other than those that can only be referenced via an extern alias) using its canonical CLR metadata name. This lookup follows the following order: If the type is found in the compilation's assembly, that type is returned. Next, the core library (the library that defines System.Object and has no assembly references) is searched. If the type is found there, that type is returned. Finally, all remaining referenced non-extern assemblies are searched. If one and only one type matching the provided metadata name is found, that single type is returned. Accessibility is ignored for this check.
GetTypesByMetadataName(String)	Gets all types with the compilation's assembly and all referenced assemblies that have the given canonical CLR metadata name. Accessibility to the current assembly is ignored when searching for matching type names.
GetUnreferencedAssemblyIdentities(Diagnostic)	Given a Diagnostic reporting unreferenced AssemblyIdentitys, returns the actual AssemblyIdentity instances that were not referenced.
GetUsedAssemblyReferences(CancellationToken)	Unique metadata assembly references that are considered to be used by this compilation. For example, if a type declared in a referenced assembly is referenced in source code within this compilation, the reference is considered to be used. Etc. The returned set is a subset of references returned by References API. The result is undefined if the compilation contains errors. The effect of imported namespaces on result of this API depends on whether reporting of unused imports is disabled for the compilation. The reporting of unused imports is disabled if DocumentationMode is set to None. When unused imports reporting is disabled, all referenced assemblies containing any types that belong to imported namespaces are included in the result. I.e. considered used. When unused imports reporting is enabled, imported namespaces do not have effect on the result of this API. Therefore, removing assembly references that aren't in the result, could potentially cause error "CS0246: The type or namespace name could not be found (are you missing a using directive or an assembly reference?)" on an unused namespace import. However, that import would be reported by compiler as unused for the compilation on which this API was invoked. In order to avoid the errors, it is recommended to remove unused assembly references and unused imports at the same time.
HasImplicitConversion(ITypeSymbol, ITypeSymbol)	Returns true if there is an implicit (C#) or widening (VB) conversion from fromType to toType. Returns false if either fromType or toType is null, or if no such conversion exists.
IsSymbolAccessibleWithin(ISymbol, ISymbol, ITypeSymbol)	Checks if symbol is accessible from within within. An optional qualifier of type throughType is used to resolve protected access for instance members. All symbols are required to be from this compilation or some assembly referenced (References) by this compilation. within is required to be an INamedTypeSymbol or IAssemblySymbol.
