您好我正在将dll加载到另一个域,它加载到该域时工作正常,但当我想通过代理对象从该域获取一些信息时,它给出了我的例外,下面是审查的代码是否有任何错误的步骤???
public class AssemblyProxy
{
System.Type[] _types;
public System.Type[] GetTypes()
{
return _types;
}
public string FullName { get; set; }
public void LoadAssembly(string path)
{
try
{
Evidence evidence = new Evidence(AppDomain.CurrentDomain.Evidence);
AppDomain TestDomain = AppDomain.CreateDomain("AssemblyDomain", evidence, AppDomain.CurrentDomain.BaseDirectory, System.IO.Path.GetFullPath(path), true);
Proxy _asmProxy = (Proxy)TestDomain.CreateInstanceFromAndUnwrap(AppDomain.CurrentDomain.BaseDirectory+"Common.dll", typeof(Proxy).FullName);
_asmProxy.LoadAssembly(path);
FullName = _asmProxy.FullName;
_types = _asmProxy.GetTypes(); //Here i got Exception [Can not load file or assembly]
AppDomain.Unload(TestDomain);
}
catch (Exception ex)
{
}
}
}
class Proxy : MarshalByRefObject
{
System.Type[] _types;
public string FullName { get; set; }
public System.Type[] GetTypes()
{
return _types;
}
public void LoadAssembly(string path)
{
System.Reflection.Assembly _assembly = System.Reflection.Assembly.Load(System.IO.File.ReadAllBytes(path));
_types = _assembly.GetTypes();
FullName = _assembly.FullName;
}
}
我得到的例外是:
无法加载文件或程序集

我解决这个问题的方法是调用LoadFrom(不是Load)和 AppDomain的上下文:
sDomain = AppDomain.CreateDomain(DOMAIN_NAME);
sDomain.DoCallBack(AppDomainCallback);
// runs in the context of the AppDomain
private void AppDomainCallback()
{
Assembly assembly = Assembly.LoadFrom(mAssemblyName);
}

我已经通过阅读以下博客文章解决了这个问题:我的问题是我从新域返回System.Type对象,这是不允许的,你可以从代理对象而不是System.Type对象返回字符串
