从其他路径加载dll [英] Load dlls from a different path

问题描述

我正在尝试让我的应用程序从其他文件夹(例如C:\)加载需要运行的dll引用，以便可以移动该exe，而无需将其dll保留在同一目录中.请帮忙！

I''m trying to get my application to load the dll references that it needs to run from another folder such as C:\ so that the exe can be moved without the need to keep its dlls in the same directory. Please help!

推荐答案

只是为了使您能够移动exe并不是此设计的正当理由. .NET可以使用xcopy部署，因此移动带有exe和程序集的文件夹没有问题.

运行时如何查找程序集 [通过代码库或探针定位程序集 [

Just so you can move the exe is not a valid reason for this design. .NET can use xcopy deployment so moving the folder, with exe and assemblies, is no problem.

How the Runtime Locates Assemblies[^]

Locating the Assembly through Codebases or Probing[^]

要获取DLL中的所有信息

TO Get All Information from DLL

Assembly assembly = Assembly.LoadFrom(@"C:\Program Files (x86)\Common Files\microsoft shared\DevServer\10.0\Additionsusersandip0.dll");
            Type[] t = assembly.GetTypes();
            foreach (Type tt in t)
            {
                if (tt.IsClass) Console.WriteLine("Name space is = " + tt.Namespace);
                MethodInfo[] mi = tt.GetMethods();
                Console.WriteLine(mi.ToString());
                foreach (MethodInfo methodinfo in mi)
                {
                    ParameterInfo[] pi = methodinfo.GetParameters();
                    Console.WriteLine(methodinfo.Name);
                    Console.WriteLine(methodinfo.ReturnType.ToString());
                    Console.WriteLine(methodinfo.ReturnParameter.ParameterType.ToString());
                    foreach (ParameterInfo p in pi)
                    {
                        p.GetType();
                        Console.WriteLine(p.Name);
                        Console.WriteLine(p.ParameterType);
                    }
                }
            }

调用DLL方法

To Invoke the DLL Method

Assembly myAssem = Assembly.LoadFile(strFullDummyDLLFilePath);
            Type[] t = myAssem.GetTypes();
            foreach (Type type in t)
            {
                // Invoke Method if the type is class only
                if (type.IsClass)
                {
                    // Load an assembly file into an object.
                    Object objAssembly = Activator.CreateInstance(type);
                    object[] objInputParams = null;
                    objResult = type.InvokeMember(strMethodName, BindingFlags.InvokeMethod,null, objAssembly, new Object[] { objIPParameters });   
                 }
            }
