C#调整图片框大小以适应窗口的全屏版本

Question

我不想改变图像大小。在创建图像之后，我添加了这个特性。我正在使用Windows (.NET框架)。我用颜料做的东西，有坐标和其他东西。现在我改变它，使它被转换，所以它在一个图片盒中，以获得更好的质量在我的动画。但我只能将picturebox大小调整为小窗口的大小。但我已经把所有的东西都放在全尺寸的窗户上了。现在我只能看到这幅画中适合小窗口的部分，也就是左上角的东西。我需要picturebox和完整的窗口一样大，这里是我的代码：

using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

Answer 1

要在picturebox上使用此代码this.WindowState = FormWindowState.Maximized;，最好也使用此符号，为了将图像填充到窗口pictureBox1.Dock = DockStyle.Fill;中，窗口也必须是无边框this.FormBorderStyle = FormBorderStyle.None;按以下顺序使用它们

1. this.FormBorderStyle = FormBorderStyle.None;
2. pictureBox1.Dock = DockStyle.Fill;
3. this.WindowState = FormWindowState.Maximized;

Answer 2

若要停止图像效果，请使用以下命令

首先，转到Form_Load并放入以下代码：

• this.KeyPreview = true;

在此之后，转到Form事件并在KeyDown中双击并将此代码放入以停止移动图像

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
      if (e.KeyCode == Keys.Space)
      {
          if(timer1.Enable == true)
          {
              timer1.Enabled = false;
              return;
          }
          if(timer1.Enable == false)
          {
              timer1.Enabled = true;
              return;
          }
      }
}

如果按空格键将停止计时器，并停止图像

如果您想要停止该图像，请自动使用以下命令

private void timer1_Tick(object sender, EventArgs e)
        {
            cloudone1 = cloudone1 + 2;
            if (cloudone1 == 1000)
            {
                timer1.Enable = false;
            }
            Invalidate();
        }
