Finding SyntaxNode of an ISymbol

Question

Given a SemanticModel instance and an ISymbol assosiated with it, is it possible to get SyntaxNode of the ISymbol?

Basicly the opposite of GetDeclaredSymbol method of SemanticModel

the only way i am aware of is searching the SyntaxTree root with a predicate, is there a way to do it with less code?

Answer 1

要从SyntaxNode获取ISymbol声明，请使用ISymbol.DeclaringSyntaxReferences。

请注意，它可以返回多个引用（例如，当您获得部分声明时）或者没有（当它在外部声明时）。

一个小例子：

var syntaxReference = propSymbol.DeclaringSyntaxReferences
                                .First()
                                .GetSyntax();

GetSyntax()将返回SyntaxNode，因此您仍应将其转换为您感兴趣的确切类型。
