在Visual Studio 2015中使用Roslyn API,我可以将对象实例转换为源代码吗?我可以创建一个类似" .ToSourceCode()"的扩展方法。如下图所示?
class Foo { }
class Program
{
static string classSourceCode = "class Foo { }";
static void Main()
{
var instance = new Foo();
var instanceSourceCode = instance.GetType().ToSourceCode();
System.Diagnostics.Debug.Assert(instanceSourceCode == classSourceCode);
}
}

没有。但是,ILSpy可以。
根据对问题的评论以及我对Roslyn的理解,不支持反编译。但是,感谢@ Bradley的ILSpy提示,有一个解决方案:
using System;
using System.Linq;
using System.Reflection;
using System.Text.RegularExpressions;
using ICSharpCode.Decompiler;
using ICSharpCode.ILSpy;
using Mono.Cecil;
class Foo { }
class Program
{
static string classSourceCode = "using System; internal class Foo { } ";
static void Main()
{
var instance = new Foo();
var instanceSourceCode = instance.GetType().ToSourceCode();
System.Diagnostics.Debug.Assert(instanceSourceCode == classSourceCode);
}
}
static class TypeExtensions
{
public static string ToSourceCode(this Type source)
{
var assembly = AssemblyDefinition.ReadAssembly(Assembly.GetExecutingAssembly().Location);
var type = assembly.MainModule.Types.FirstOrDefault(t => t.FullName == source.FullName);
if (type == null) return string.Empty;
var plainTextOutput = new PlainTextOutput();
var decompiler = new CSharpLanguage();
decompiler.DecompileType(type, plainTextOutput, new DecompilationOptions());
return Regex.Replace(Regex.Replace(plainTextOutput.ToString(), @"\n|\r", " "), @"\s+", " ");
}
}
