动态调用方法 .net

 ///返回接口类

public IFlowCustomAction GetCustomAction(string flowName){

var fix = "LwAction";

var type =Type.GetType("Web.CustomAction." + flowName );//路径+方法名

return Dynamic.InvokeConstructor(type);//动态执行

}

IFlowCustomAction customAction = GetCustomAction(FlowName);

customAction.LoadForm(data, this, userId);

//然后就可以调用  IFlowCustomAction  接口重写之后的方法

//IFlowCustomAction 为接口类 type 为重写方法

//IFlowCustomAction.cs

public interface IFlowCustomAction
{

object LoadForm(WeiXinModel data, FlowData flow, string userId);

}

//动态方法

public class LwAction: DefaultAction
{

public override object LoadForm(WeiXinModel data, FlowData flow, string userId)

{ //重写方法 }

}
