使用 Roslyn 解析 类 函数和属性
using Roslyn to parse classes functions and properties
我是 Roslyn 的新手，我正在尝试解析一个 cs 文件并获取函数和属性。
API 例子
//won't work any more
var tree = SyntaxTree.ParseText(...);
var tree = SyntaxTree.ParseFle(...);
var root = tree.Root;
API好像变了，不能用了。猜猜它仅在外观上适用于 2012 Roslyn CTP。
然后我尝试更新的示例：
//won't work neither
var compilation = CSharpCompilation.Create("HelloWorld")
.AddReferences( new MetadataFileReference(
typeof(object).Assembly.Location)) .AddSyntaxTrees(tree);
var tree = CSharpSyntaxTree.ParseText(strSourceCode);
var root = tree.GetRoot();
同样，它不再起作用，因为 MetadataFileReference 在我得到的 Roslyn 版本中是一个抽象 class。 API又变了？我不确定。
VS 和包
我在公司电脑上使用 VS2013 PRO UPDATE 2。 2015 年 7 月 5 日至今。
不，我没有装有 VS2015 的计算机，我不确定这是否重要。
我打开一个新的 WinForm 项目，然后在 NuGet PM 中我按照 https://github.com/dotnet/roslyn 的指示安装了 Roslyn。这是我的安装日志：

我的目标
我只想：
- 将 cs 文件或一些源字符串读入编译器。
- 解析出 class 个名称和函数 属性 个名称。
- 解析函数和属性及其参数和 return 类型。
我可以提供一些工作示例吗？
这里有几件事：
我强烈建议您使用 Visual Studio 2015 来完成与 Roslyn 相关的任务。 Roslyn 的某些部分依赖于 VS 2015 和最新的 MSBuild 工具。 Visual Studio 2015社区也免费了！
注意：我还建议使用 NuGet 的 rc-2 位，而不是 rc-3 位。你在一个奇怪的时间（在发布之间）进入了 Roslyn 世界，这应该会让你的生活更轻松，直到 VS2015 于 7 月 20 日发布。
使用以下命令从 NuGet 安装：
Install-Package Microsoft.CodeAnalysis -Version 1.0.0-rc2 -Pre
在下面使用CreateFromAssembly:
var tree = CSharpSyntaxTree.ParseText(@"
class TestClass
{
void TestMethod ()
{
int i;
}
}");
var Mscorlib = MetadataReference.CreateFromAssembly(typeof(object).Assembly);
var compilation = CSharpCompilation.Create("MyCompilation",
syntaxTrees: new[] { tree }, references: new[] { Mscorlib });
var model = compilation.GetSemanticModel(tree);
我是 Roslyn 的新手，我正在尝试解析一个 cs 文件并获取函数和属性。

//won't work any more
