这是一个晚回答，但对于未来查看此问题的任何人都将是有价值的。我需要以动态代码编译/执行方式实现类似的功能。最好的方法是在主AppDomain之外的远程域中执行所有方法，否则应用程序内存将不断增加。您可以通过远程接口和代理解决此问题。
因此，您将通过接口公开方法，在主AppDomain中获取其实例，然后在远程域中远程执行这些方法，卸载新创建的域（远程域），将其置空，然后强制GC收集未使用的对象。我花了很长时间调试我的代码，直到我意识到我必须强制GC这样做，它才能正常工作。我的大部分实现都来自：
http://www.west-wind.com/presentations/dynamicCode/DynamicCode.htm。
object ExecuteCodeDynamically(string code)
{
Create AppDomain my_app
src_code = "using System; using System.Reflection; using RemoteLoader;
namespace MyNameSpace{
public class MyClass:MarshalByRefObject, IRemoteIterface
{
public object Invoke(string local_method, object[] parameters)
{
return this.GetType().InvokeMember(local_method, BindingFlags.InvokeMethod, null, this, parameters);
}
public object ExecuteDynamicCode(params object[] parameters)
{
" + code + } } } ";// this whole big string is the remote application
//compile this code which is src_code
//output it as a DLL on the disk rather than in memory with the name e.g.: DynamicHelper.dll. This can be done by playing with the CompileParameters
// create the factory class in the secondary app-domain
RemoteLoader.RemoteLoaderFactory factory =
(RemoteLoader.RemoteLoaderFactory)loAppDomain.CreateInstance("RemoteLoader",
"RemoteLoader.RemoteLoaderFactory").Unwrap();
// with the help of this factory, we can now create a real instance
object loObject = factory.CreateInstance("DynamicHelper.dll", "MyNamespace.MyClass", null);
// *** Cast the object to the remote interface to avoid loading type info
RemoteLoader.IRemoteInterface loRemote = (RemoteLoader.IRemoteInterface)loObject;
if (loObject == null)
{
System.Windows.Forms.MessageBox.Show("Couldn't load class.");
return null;
}
object[] loCodeParms = new object[1];
loCodeParms[0] = "bla bla bla";
try
{
// *** Indirectly call the remote interface
object result = loRemote.Invoke("ExecuteDynamicCode", loCodeParms);// this is the object to return
}
catch (Exception loError)
{
System.Windows.Forms.MessageBox.Show(loError.Message, "Compiler Demo",
System.Windows.Forms.MessageBoxButtons.OK,
System.Windows.Forms.MessageBoxIcon.Information);
return null;
}
loRemote = null;
try { AppDomain.Unload(my_app); }
catch (CannotUnloadAppDomainException ex)
{ String str = ex.Message; }
loAppDomain = null;
GC.Collect();//this will do the trick and free the memory
GC.WaitForPendingFinalizers();
System.IO.File.Delete("ConductorDynamicHelper.dll");
return result;
}
请注意，RemoteLoader是另一个DLL，应该已经创建并添加到您的主应用程序和远程应用程序中。它基本上是一个接口和工厂加载器。以下代码摘自上述网站：
public interface IRemoteInterface
{
object Invoke(string lcMethod,object[] Parameters);
}
naemspace RemoteLoader{
public class RemoteLoaderFactory : MarshalByRefObject
{
private const BindingFlags bfi = BindingFlags.Instance | BindingFlags.Public | BindingFlags.CreateInstance;
public RemoteLoaderFactory() {}
public IRemoteInterface Create( string assemblyFile, string typeName, object[] constructArgs )
{
return (IRemoteInterface) Activator.CreateInstanceFrom(
assemblyFile, typeName, false, bfi, null, constructArgs,
null, null, null ).Unwrap();
}
}
}
希望这有意义并能帮到你...
