C# 使用反射技术加载程序集（Assembly）并利用Activator创建实例

在C#语言编程中可以使用Assembly的反射技术加载程序集或获取当前运行的程序集，进而利用Activator使用类的完全名称创建对应的实例。

使用Assembly加载程序集： Assembly.Load(rootPath + "Qidian.SEO.Baidu.Station.dll");

string rootPath = AppDomain.CurrentDomain.SetupInformation.ApplicationBase;
var assembly = Assembly.Load(rootPath + "Qidian.SEO.Baidu.Station.dll");

Assembly加载运行中的程序集： Assembly assembly = Assembly.GetExecutingAssembly();

Assembly assembly = Assembly.GetExecutingAssembly();

Assembly获取所有程序集： AppDomain.CurrentDomain.GetAssemblies();

var assemblys = AppDomain.CurrentDomain.GetAssemblies();

从全部程序集种获取对应名称的程序集

var assemblys = AppDomain.CurrentDomain.GetAssemblies();
var assembly = assemblys.Where(p => "Qidian.SEO.Baidu.Station.Model.UserInfo".Contains(p.GetName().Name)).FirstOrDefault();
Type type = assembly.GetType("Qidian.SEO.Baidu.Station.Model.UserInfo");
var instance = Activator.CreateInstance(type).GetType();
var bb = OrmProvider.Query(instance);

Assembly获取引用程序集

public static class Extents
{
    public static List<Assembly> GetReferanceAssemblies(this AppDomain domain)
    {
        var list = new List<Assembly>();
        domain.GetAssemblies().ForEach(i =>
        {
            GetReferanceAssemblies(i, list);
        });
        return list;
    }
    static void GetReferanceAssemblies(Assembly assembly, List<Assembly> list)
    {
        assembly.GetReferencedAssemblies().ForEach(i =>
        {
            var ass = Assembly.Load(i);
            if (!list.Contains(ass))
            {
                list.Add(ass);
                GetReferanceAssemblies(ass, list);
            }
        });
    }
}

Activator创建实例Activator.CreateInstance(type);

Type type = assembly.GetType("Qidian.SEO.Baidu.Station.UserInfo");
var instance = Activator.CreateInstance(type);
