WPF无边框窗体怎么移动？C#

我想做一个WPF窗体，没有边框，怎么靠鼠标左键拖动窗体位置？不要API……
是WPF窗体不是WinForm窗体，WPF的MouseEventArgs和WinForm的不一样，求用法

Answer 1

不好意思，没看清提问，不要api的方法如下：

private bool leftFlag = false;
private Point mouseOff;

private void toolStrip2_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
mouseOff = new Point(-e.X, -e.Y); //得到变量的值
leftFlag = true; //点击左键按下时标注为true;
}
}

private void toolStrip2_MouseMove(object sender, MouseEventArgs e)
{
if (leftFlag)
{
Point mouseSet = Control.MousePosition;
mouseSet.Offset(mouseOff.X, mouseOff.Y); //设置移动后的位置
Location = mouseSet;
}
}

private void toolStrip2_MouseUp(object sender, MouseEventArgs e)
{
if (leftFlag)
{
leftFlag = false;//释放鼠标后标注为false;
}
}

ps：这种方法很不好，鼠标移动快就会出问题

[DllImport("user32.dll")]
public static extern bool ReleaseCapture();
[DllImport("user32.dll")]
public static extern bool SendMessage(IntPtr hwnd,int wMsg,int wParam,int lParam);
public const int WM_SYSCOMMAND=0x0112;
public const int SC_MOVE=0xF010;
public const int HTCAPTION=0x0002;
private void Form1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{//拖动窗体
ReleaseCapture();
SendMessage(this.Handle,WM_SYSCOMMAND,SC_MOVE+HTCAPTION, 0);
}

Answer 3

private void Window_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
this.DragMove();
}

Answer 4

你是不是WindowStyle="None"?
如果是那就简单多了
private void Window_MouseDown(object sender, MouseButtonEventArgs e)
{
if (e.LeftButton == MouseButtonState.Pressed)
{
DragMove();
}
}
