C# 按钮保存点击获取 MaintenanceMetrics() 下所有控件的值 - 代码示例

private void But_Click(object sender, RoutedEventArgs e)
{
    // 获取内部Grid
    Grid innerGrid = (Grid)((StackPanel)((Button)sender).Parent).Parent;
    // 获取所有TextBox的值
    List<string> values = new List<string>();
    foreach (StackPanel stackPanel in innerGrid.Children)
    {
        foreach (TextBox textBox in stackPanel.Children.OfType<TextBox>())
        {
            values.Add(textBox.Text);
        }
    }
    // 获取ComboBox的值
    string indexName = ((ComboBox)innerGrid.FindName('indexName')).Text;
    // 处理数据
    // ...
}

代码说明:

1. 获取内部 Grid: 使用 (Grid)((StackPanel)((Button)sender).Parent).Parent 获取包含所有输入控件的 Grid。
2. 获取 TextBox 值: 循环遍历 Grid 内的 StackPanel，然后使用 OfType<TextBox>() 获取每个 StackPanel 中的 TextBox，并将它们的 Text 属性值添加到 values 列表中。
3. 获取 ComboBox 值: 使用 FindName() 方法通过名称获取 ComboBox 控件，然后获取其 Text 属性值。
4. 处理数据: 您可以根据实际需要将获取的 values 列表和 indexName 进行进一步处理。
