基于插件的应用程序在C#

public List<T> LoadPlugin<T>(string directory)
    {
        Type interfaceType = typeof(T);
        List<T> implementations = new List<T>();

        //TODO: perform checks to ensure type is valid

        foreach (var file in System.IO.Directory.GetFiles(directory))
        {
            //TODO: add proper file handling here and limit files to check
            //try/catch added in place of ensure files are not .dll
            try
            {
                foreach (var type in System.Reflection.Assembly.LoadFile(file).GetTypes())
                {
                    if (interfaceType.IsAssignableFrom(type) && interfaceType != type)
                    { 
                        //found class that implements interface
                        //TODO: perform additional checks to ensure any
                        //requirements not specified in interface
                        //ex: ensure type is a class,check for default constructor,etc
                        T instance = (T)Activator.CreateInstance(type);
                        implementations.Add(instance);
                    }
                }
            }
            catch { }
        }

        return implementations;
    }

调用示例

List<IPlugin> plugins = LoadPlugin<IPlugin>(path);

对于你的问题的c部分.有几种不同的方法可以解决这个问题,但是正确的选择取决于你的具体情况.你可以在c中创建一个clr兼容的.dll,你的c#项目可以引用它,并且像其他引用的其他.dll一样调用.此外,您可以使用P/Invoke调用本机.dll.
