動態調用方法 .net

 ///返回接口類

public IFlowCustomAction GetCustomAction(string flowName){

var fix = "LwAction";

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

return Dynamic.InvokeConstructor(type);//動態執行

}

IFlowCustomAction customAction = GetCustomAction(FlowName);

customAction.LoadForm(data, this, userId);

//然後就可以調用  IFlowCustomAction  接口重寫之後的方法

//IFlowCustomAction 爲接口類 type 爲重寫方法

//IFlowCustomAction.cs

public interface IFlowCustomAction
{

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

}

//動態方法

public class LwAction: DefaultAction
{

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

{ //重寫方法 }

}
