c# - 委托(delegate)和事件

Question

我有 2 个表格。

表格 1:

public partial class Panel1
    {
        public void ShowExport(object sender, EventArgs e)
        {
           .......
        }
    }

表格 2:

public partial class Panel2
{
        public delegate void ShowExportReport(object sender, EventArgs e);
        public event ShowExportReport ShowExportClicked;

private void buttonExport_Click(object sender, RoutedEventArgs e)
        {         
           if (ShowExportClicked != null)
            {
                ShowExportClicked(sender, new EventArgs());
            }                     

        }
}

当我点击按钮时——

button.Click = buttonExport_Click

如何从 Panel2.buttonExport_Click 调用 Panel1.ShowExport()？

Answer 1

在 Panel1 中你必须订阅事件:

pnl2.ShowExportClicked += new ShowExportReport(ShowExport);
