c# - 如何使用 Roslyn (Microsoft CodeAnalysis) 获取范围内的所有可见局部变量名称

Question

(请注意:这与运行时反射/元信息无关)

我正在编写 Roslyn CSharpSyntaxVisitor 的具体实现

实现 VisitIdentifierName 时

public override SyntaxNode VisitIdentifierName(IdentifierNameSyntax name)
{
   var symbolInfo = _semanticModel.GetSymbolInfo(name);
   var fieldSymbol = symbolInfo.Symbol as IFieldSymbol;
   if (fieldSymbol != null)
   {
       // Here I would like to get all the local variable names what are visible
       // in the very same scope where this field IdentifierNameSyntax under visiting resides
       // We can suppose that _semanticNodel for the Document is available.
   }
}

Answer 1

调用SemanticModel.LookupSymbols() ( source )，然后过滤局部变量。

您可能还想过滤掉在该位置之后声明的本地人；见this code .
