如何从Roslyn中的语句获取参数到变量

Question

到目前为止，我已经能够在method.body中找到Console.WriteLine（“Hello World”）语句。但我想从WriteLine（“Hello World”）收集“Hello World”字符串;声明。我怎么能这样做？我的代码：

MethodDeclarationSyntax method = syntaxTree.GetRoot()
                                           .DescendantNodes()
                                           .OfType<MethodDeclarationSyntax>()
                                           .First();
BlockSyntax statement = method.Body;
ControlFlowAnalysis controlFlow = semanticModel.AnalyzeControlFlow(statement);
StatementSyntax state = statement.Statements.First();

Console.WriteLine(state.ToString());
Console.ReadLine();
