Question

我确信做这样的事情不是好习惯，但我只是好奇如果有可能......

我尝试使用Visual Studio 2015但是我收到了多个编译错误（很多人要发布） - 但基本上我很好奇的是你是否可以在不同的类中使用文本框的_Leave（）事件。像下面的东西

namespace BlueGreenRed
{
    public partial class Red : UserControl
    {
        //In this class I have a text box called txtName
    }
}



namespace BlueGreenRed
{
    class ReusableMethods
    {
        private void txtName_Leave(object sender, EventArgs e)
        {
            //Do something here
        }
    }
}

当然你可以这样做：

public class Red 
{
    public TextBox TxtName {get; set; }
}

public static class ReusableMethods
{
    public static void WireUp(Red red)
    {
         red.TxtName.Leave += txtName_Leave;
    }

    private static void txtName_Leave(object sender, EventArgs e)
    {
        //Do something here
    }
}

//some other code

var red1 = new Red() { TxtName = new TextBox() };
var red2 = new Red() { TxtName = new TextBox() };

ReusableMethods.WireUp(red1);
ReusableMethods.WireUp(red2);

有不同类的文本框事件
