C＃中的逆向工程

Question

我需要从编译的dll中提取依赖项列表。 dll是用c＃或vb.net编写的，并且此过程应以递归方式完成，即，依赖项可能具有自己的依赖项，依此类推。

Telerik的“ JustDecompile”工作得很好，但是我想编写实现此目的的代码，因此我可以使用一棵依赖树。

有任何想法吗？

Answer 1

您不需要任何特殊的东西，可以使用内置的System.Reflection类：

public static void DisplayReferences() {

     Assembly assembly = Assembly.Load( ... );
     HashSet<String> seen = new HashSet<String>();
     DisplayReferences( 0, seen, assembly.GetName() );
}

private static void DisplayReferences(Int32 indent, HashSet<String> seen, AssemblyName name) {

    Assembly assembly = Assembly.Load( name )
    foreach(AssemblyName childName in assembly.GetReferencedAssemblies() ) {

        if( !seen.Contains( childName.FullName ) ) {

            seen.Add( childName.FullName );
            Console.WriteLine( "{0}{1}", "".PadLeft( indent ), childName.FullName );
            DisplayReferences( indent + 1, childName );
        }

    }
}

Answer 2

我的代码版本（显示依赖程序集的所有依赖关系）：

public IEnumerable<Assembly> GetAssemblyDependencies(Assembly assembly)
{
    HashSet<string> hash = new HashSet<string>();

    Func<AssemblyName, Assembly> loader = (name) =>
    {
        try
        {
            return Assembly.Load(name.FullName);
        }
        catch
        {
            return null;
        }
    };

    List<Assembly> queue = new List<Assembly>() { assembly };
    List<Assembly> newQueue = new List<Assembly>();
    while (queue.Count != 0)
    {
        foreach (var asm in queue.SelectMany(e => from x in e.GetReferencedAssemblies()
                                                  let loadedAssembly = loader(x)
                                                  where loadedAssembly != null
                                                  select loadedAssembly))
        {
            string fullName = asm.FullName;
            if (!hash.Contains(fullName))
            {
                // new assembly
                hash.Add(fullName);
                yield return asm;
                newQueue.Add(asm);
            }
        }

        var temp = queue;
        queue = newQueue;
        newQueue = temp;
        newQueue.Clear();
    }
}

用法：

foreach (var assembly in from e in 
GetAssemblyDependencies(this.GetType().Assembly)
                         orderby e.FullName
                         select e)
{
    Console.WriteLine(assembly.FullName);
}

结果（对于我的测试控制台）：
