c#中的逆向工程

本文关键字：逆向工程 | 更新日期: 2023-09-27 17:52:53

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，这个过程应该递归地完成，即一个依赖项可能有它自己的依赖项，等等。

Telerik的"JustDecompile"工作得很好，但是我想编写这样的代码，这样我就可以有一个依赖关系树。

任何想法?

c#中的逆向工程

我的代码版本(显示依赖程序集的所有依赖项):

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(我的测试控制台):

您不需要任何特别的东西，您可以使用内置的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 );
        }
    }
}
