用反射调用任意.Net库中的方法

注:

1、ReturnMessage 是我自写的一个类，作用请查看我的其他文章，我也把这个类一并附在后面

2、通过NameSpaceAndClassName和MethodName实际上就可以精确定位一个方法了如调用abc.dll里的namespace1.Class1.Main，调用起来就是CallAssembly("abc.dll","namespace1.Class1","Main",null)

 

public static ReturnMessage CallAssembly(string Path,string NameSpaceAndClassName,string MethodName,object[] Parameters)
        {
            try
            {
                Assembly Ass=Assembly.LoadFrom(Path);//调入文件(不限于dll,exe亦可,只要是.net)
                Type TP=Ass.GetType(NameSpaceAndClassName);//NameSpaceAndClassName是"名字空间.类名",如"namespace1.Class1"
                MethodInfo MI=TP.GetMethod(MethodName);//MethodName是要调用的方法名,如"Main"
                object MeObj=System.Activator.CreateInstance(TP);
                MI.Invoke(MeObj,Parameters);//Parameters是调用目标方法时传入的参数列表
                return new ReturnMessage(true,"成功调用",1);
            }
            catch(Exception e)
            {
                return new ReturnMessage(false,"出现异常,消息为:"+e.Message,-1,e);
            }
        }

 

附ReturnMessage

public class ReturnMessage
    {
        public ReturnMessage()
        {
            this.m_Succeed=false;
            this.m_Message="";
            this.m_Code=-1000;
            this.m_Data=null;
        }
        public ReturnMessage(bool IsSucceed)
        {
            this.m_Succeed=IsSucceed;
        }
        public ReturnMessage(bool IsSucceed,string Message)
        {
            this.m_Succeed=IsSucceed;
            this.m_Message=Message;
        }
        public ReturnMessage(bool IsSucceed,string Message,int Code)
        {
            this.m_Succeed=IsSucceed;
            this.m_Message=Message;
            this.m_Code=Code;
        }
        public ReturnMessage(bool IsSucceed,string Message,int Code,object Data)
        {
            this.m_Succeed=IsSucceed;
            this.m_Message=Message;
            this.m_Code=Code;
            this.m_Data=Data;
        }
        public ReturnMessage(bool IsSucceed,string Message,int Code,object Data,object[] Datas)
        {
            this.m_Succeed=IsSucceed;
            this.m_Message=Message;
            this.m_Code=Code;
            this.m_Data=Data;
            this.m_Datas=Datas;
        }
        //
        bool m_Succeed;
        string m_Message;
        int m_Code;
        object m_Data;
        object[] m_Datas;
        public bool Succeed
        {
            get{return m_Succeed;}
            set{m_Succeed=value;}
        }
        public string Message
        {
            get{return m_Message;}
            set{m_Message=value;}
        }
        public int Code
        {
            get{return m_Code;}
            set{m_Code=value;}
        }
        public object Data
        {
            get{return m_Data;}
            set{m_Data=value;}
        }
        public object[] Datas
        {
            get{return m_Datas;}
            set{m_Datas=value;}
        }
    }
