我需要从编译后的dll中提取依赖列表。这个DLL是用c＃或者vb.net编写的，这个过程应该是递归的，也就是说一个依赖可能依赖于它自己，等等。编写这样做的代码，这样我就可以拥有一棵依赖关系树。c中的逆向工程＃
任何想法？

你并不需要什么特别的，你可以使用内置的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);
}
}
}

这个答案不处理罕见但可能的情况，其中传递闭包的程序集中有循环引用。其他答案正确处理这种情况。 –

@EricLippert我不知道循环引用是可能的，我认为运行时或JIT编译器会抱怨并中止。 – Dai

我的代码版本（显示依赖组件的所有依赖）：
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（用于我的测试控制台）：
