子窗体、主窗体传参

在主窗体里面操纵子窗体的控件

子窗体

<Label x:Name="DialogLabel"></Label>

主窗体

<Grid> <Grid.RowDefinitions> <RowDefinition Height="*"></RowDefinition> <RowDefinition Height="*"></RowDefinition> </Grid.RowDefinitions> <TextBox Margin="20" x:Name="InputTextBox"></TextBox> <Button Margin="20" Grid.Row="1" Content="打开弹窗" Click="OpenDialog"></Button> </Grid>

主窗体点击事件操作

private void OpenDialog(object sender, RoutedEventArgs e) { Dialog dialog = new Dialog(); //在主窗体里面操纵子窗体的控件 dialog.DialogLabel.Content = InputTextBox.Text; dialog.ShowDialog(); }

直接在主窗体里面操纵子窗体的控件，进行一系列操作，业务逻辑也放在主窗体
