错误信息：System.InvalidCastException：无法将“ClassLibrary1.Plugin”类型的对象转换为“PluginInterface.IPlugin”类型。
我想做的是让我的程序访问一个程序集并运行它可能拥有的任何东西。这会加载 .dll
private void AddPlugin(string FileName)
{
Assembly pluginAssembly = Assembly.LoadFrom(FileName);
foreach (Type pluginType in pluginAssembly.GetTypes())
{
if (pluginType.IsPublic)
{
if (!pluginType.IsAbstract)
{
Type typeInterface = pluginType.GetInterface("PluginInterface… true);
if (typeInterface != null)
{
Types.AvailablePlugin newPlugin = new Types.AvailablePlugin();
newPlugin.AssemblyPath = FileName;
newPlugin.Instance = (IPlugin)Activator.CreateInstance(plugin…
// Above line throws exception.
newPlugin.Instance.Initialize();
this.colAvailablePlugins.Add(newPlugin);
newPlugin = null;
}
typeInterface = null;
}
}
}
pluginAssembly = null;
}
我的程序和我的程序集都有这两个接口：
using System;
namespace PluginInterface
{
public interface IPlugin
{
IPluginHost Host { get; set; }
string Name { get; }
string Description { get; }
string Author { get; }
string Version { get; }
System.Windows.Forms.Form MainInterface { get; }
void Initialize();
void Dispose();
void ReceivedMessage(PlayerIOClient.Message m);
void Disconnected();
}
public interface IPluginHost
{
void Say(string message);
void Send(PlayerIOClient.Message m);
void Send(string message_Type, params object[] paramss);
}
}
我要添加的班级/大会：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Threading;
using PluginInterface;
namespace ClassLibrary1
{
public class Plugin : IPlugin // <-- See how we inherited the IPlugin interface?
{
public Plugin()
{
}
string myName = "Title";
string myDescription = "Descrip";
string myAuthor = "Me";
string myVersion = "0.9.5";
IPluginHost myHost = null;
Form1 myMainInterface = new Form1();
public string Description
{
get { return myDescription; }
}
public string Author
{
get { return myAuthor; }
}
public IPluginHost Host
{
get { return myHost; }
set { myHost = value; }
}
public string Name
{
get { return myName; }
}
public System.Windows.Forms.Form MainInterface
{
get { return myMainInterface; }
}
public string Version
{
get { return myVersion; }
}
public void Initialize()
{
//This is the first Function called by the host...
//Put anything needed to start with here first
MainInterface.Show();
}
public void ReceivedMessage(PlayerIOClient.Message m)
{
}
public void Disconnected()
{
}
public void Dispose()
{
MainInterface.Dispose();
}
}
}
非常感谢所有帮助。
