C#中在定义事件委托时怎样跨窗体传递参数

场景

C#中委托与事件的使用-以Winform中跨窗体传值为例：

参照上文在定义事件时传递参数为简单的string，如果要传递比较复杂的参数，那么就可以使用对象将参数进行封装。

实现

在窗体A中定义委托与事件

public delegate void RefreshChartInOneDelegete(XYModel xYModel);
public static event RefreshChartInOneDelegete OnRefreshChartInOne;

其中XYModel就是自己封装的参数的Model，具体可以根据需要自己封装。

public class XYModel
    {
        //存储X轴属性
        private XAxisModel xAxisModel;
        //存储Y轴属性
        private List<YAxisModel> yAxisModelList;

       
        public XAxisModel XAxisModel
        {
            get { return xAxisModel; }
            set { xAxisModel = value; }
        }

        public List<YAxisModel> YAxisModelList
        {
            get { return yAxisModelList; }
            set { yAxisModelList = value; }
        }
    }

定义触发器

xYModel.YAxisModelList = yAxisModelList;
            if (OnRefreshChartInOne != null)
            {
                OnRefreshChartInOne(xYModel);
               
            }

然后在窗体B中进行事件订阅

FrmChartOptionInOneCurCom.OnRefreshChartInOne += new FrmChartOptionInOneCurCom.RefreshChartInOneDelegete(ChartCompareHelper_OnRefreshChart);

在窗体B中编写具体的实现

private void ChartCompareHelper_OnRefreshChart(XYModel xYModel)
        {
            xYModelStore = xYModel;
            ChartCompareHelper.RefreshPaneComInOne(this.zedGraphControl1,xYModel.YAxisModelList);
        }
