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);
            }
