如何重新加载的.NET应用程序域的组件？ [英] How to reload an assembly for a .NET Application Domain?

问题描述

我们正在加载的组件（一个DLL），该读取的配置文件。我们需要修改配置文件，然​​后重新加载程序集。我们看到，加载组件的第二时间之后，有在配置没有变化。 任何人看到这里有什么问题？我们离开读取配置文件中的细节。

We are loading an assembly (a DLL) which reads a configuration file. We need to change the configuration file and then re-load the assembly. We see that after loading the assembly the 2nd time, there is no change in the configuration. Anyone see what is wrong here? We left out the details of reading in the configuration file.

AppDomain subDomain;
string assemblyName = "mycli";
string DomainName = "subdomain"; 
Type myType;
Object myObject;

// Load Application domain + Assembly
subDomain = AppDomain.CreateDomain( DomainName,
                                    null,
                                    AppDomain.CurrentDomain.BaseDirectory,
                                    "",
                                    false);

myType = myAssembly.GetType(assemblyName + ".mycli");
myObject = myAssembly.CreateInstance(assemblyName + ".mycli", false, BindingFlags.CreateInstance, null, Params, null, null);

// Invoke Assembly
object[] Params = new object[1];
Params[0] = value;
myType.InvokeMember("myMethod", BindingFlags.InvokeMethod, null, myObject, Params);

// unload Application Domain
AppDomain.Unload(subDomain);

// Modify configuration file: when the assembly loads, this configuration file is read in

// ReLoad Application domain + Assembly
// we should now see the changes made in the configuration file mentioned above
