没有工作区的Roslyn解析语法树

Question

I am trying to use Roslyn to create a C# code editor. I would like to get a resolved syntax tree so that I can add code completion support.

However, I cannot use Workspaces since they are broken on iOS.

I am therefore trying to hit the C# compiler directly using Compilations (is this right?). The API is simple enough, but I cannot figure out how to get member information for types.

Specifically, I would like to see a Members property of the class C that includes a reference to the fully declared D class.

However, the INamedTypeSymbol doesn't have any useful info attached to it.

How do I get rich type info from a CSharpCompilation?

var cst = Microsoft.CodeAnalysis.CSharp.SyntaxFactory.ParseCompilationUnit (
    "public class C { public D foo; }");
var dst = Microsoft.CodeAnalysis.CSharp.SyntaxFactory.ParseCompilationUnit (
    "public class D { public C bar; }");

var comp = Microsoft.CodeAnalysis.CSharp.CSharpCompilation.
    Create ("Poo").
    AddSyntaxTrees (cst.SyntaxTree).
    AddSyntaxTrees (dst.SyntaxTree);

var classC = comp.GetSymbolsWithName (n => n == "C").FirstOrDefault (); //= C
var classD = comp.GetSymbolsWithName (n => n == "D").FirstOrDefault (); //= D

var otherClassC = comp.GetTypeByMetadataName ("C"); //= C

Console.WriteLine ("C = " + classC);

您正在寻找GetMembers()方法 ，该方法返回该类型中所有已声明的成员。
