C# 在c中提升图片框上的鼠标滚轮事件#

在看了，看了，看了，我已经编码了下面的片段，好吧。。。。不工作（即，鼠标滚轮在VS2013、Win7、x64中无法启动）。恳求任何帮助

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Drawing;

namespace MyWinForm
{
    class Program
    {
        private Form theForm;
        private PictureBox thePictureBox;
        static void Main(string[] args)
        {

            Program theProgram = new Program();
            Application.Run(theProgram.theForm);

        }

        Program()
        {
            theForm = new Form();
            thePictureBox = new PictureBox();
            theForm.Controls.Add(thePictureBox);
            thePictureBox.Image = Image.FromFile(@"D:\cameraman.bmp");
            thePictureBox.Width = theImage.Width;
            thePictureBox.Height = theImage.Height;
            thePictureBox.MouseWheel += new MouseEventHandler(this.PictureBox_MouseWheel);
            thePictureBox.MouseHover += new EventHandler(this.PictureBox_MouseHover);

        }

        private void PictureBox_MouseWheel(object sender, MouseEventArgs e)
        {
            Console.WriteLine("2 + 2 = 5");//Will never get here....

        }
        private void PictureBox_MouseHover(object sender, EventArgs e)
        {
            thePictureBox.Focus();


        }
    }
}

使用mouseMove而不是mousehover对我有效：

        pictureBox1.MouseMove += newEventHandler(this.PictureBox_MouseHover);

现在只需将名称从“悬停”更改为“移动”即可：p

鼠标滚轮事件是鼠标中心事件。您必须滚动鼠标中心，然后将处理鼠标滚轮事件。

以防其他人正在寻找解决方案。 要生成pictureBox1 fire MouseWheel事件，我添加了一个MouseEnter事件：

private void pictureBox1_MouseEnter(object sender, EventArgs e)
    {
        pictureBox1.Focus();
    }

当我尝试时，您的代码运行得非常好。您是如何测试它的？Ctrl+F5->附加到进程->鼠标滚轮回调中的断点在将鼠标旋转到窗体上时不会被击中
