本文介绍如何使用C#实现窗口动画效果及位置精确调整。通过调用Win32 API函数`AnimateWindow`和`SetWindowPos`，可以为窗体添加滑动、淡入淡出等动画，并将其精确定位到屏幕指定位置。

public class Win32
{
public const Int32 AW_HOR_POSITIVE = 0x00000001;
public const Int32 AW_HOR_NEGATIVE = 0x00000002;
public const Int32 AW_VER_POSITIVE = 0x00000004;
public const Int32 AW_VER_NEGATIVE = 0x00000008;
public const Int32 AW_CENTER = 0x00000010;
public const Int32 AW_HIDE = 0x00010000;
public const Int32 AW_ACTIVATE = 0x00020000;
public const Int32 AW_SLIDE = 0x00040000;
public const Int32 AW_BLEND = 0x00080000;
[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern bool AnimateWindow(
IntPtr hwnd, // handle to window
int dwTime, // duration of animation
int dwFlags // animation type
);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern bool SetWindowPos(
IntPtr hwnd,
int hWndInsertAfter,
int x,
int y,
int cx,
int cy,
int wFlags
);

}

form load 里

int x = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Size.Width - this.Width-10;
int y = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Size.Height - this.Height-10;
this.SetDesktopLocation(x, y);

Win32.SetWindowPos(this.Handle, 100, Screen.PrimaryScreen.Bounds.Width - this.Width, Screen.PrimaryScreen.Bounds.Height - this.Height - 30, 50, 50, 1);
Win32.AnimateWindow(this.Handle, 500, Win32.AW_VER_NEGATIVE);
