Question

首先，我无法想到比这更好的标题

目前我有一个方法可以从switch语句动态创建控件。

除控件本身外，每个控件的代码都相同。

代码：

            switch (control)
            {
                case "TextBox":
                    TextBox txt = new TextBox();
                    txt.Name = "txt" + labeltext;
                    txt.Margin = _controlMargin;
                    txt.HorizontalAlignment = HorizontalAlignment.Stretch;
                    txt.FlowDirection = FlowDirection.LeftToRight;
                    txt.HorizontalContentAlignment = HorizontalAlignment.Left;
                    break;
                case "ComboBox":
                    ComboBox cbo = new ComboBox();
                    cbo.Name = "cbo" + labeltext;
                    cbo.Margin = _controlMargin;
                    cbo.HorizontalAlignment = HorizontalAlignment.Stretch;
                    cbo.FlowDirection = FlowDirection.LeftToRight;
                    cbo.HorizontalContentAlignment = HorizontalAlignment.Left;
                    break;
}

是否可以将重复代码转换为方法，或者有更好的方法吗？

Control control = null;

switch (controlType)
{
   case "TextBox":
       control = new TextBox(); 
       control.Name = "txt + labelText;
       break; 
   case "ComboBox":
       control = new ComboBox(); 
       control.Name = "cbo" + labelText;
       break;
}

control.Margin = _controlMargin; 
control.HorizontalAlignment = HorizontalAlighment.Stretch;
control.FlowDirection = FlowDirection.LeftToRight;
control.HorizontalContentAlignment = HorizontalAlignment.Left

动态添加控件而不会单调
