如何检测任务栏的位置？我需要知道在右上角显示我的通知。谢谢
Edit: Thank you Hans Passant. I used that with this to get location. I hope is ok.
编辑：谢谢汉斯·帕桑特。我用它来获取位置。我希望没事。
GetTaskbarLocation(TaskbarPosition.GetTaskbarPosition());
private void GetTaskbarLocation(Rectangle rc)
{
if (rc.X == rc.Y)
{
if (rc.Right < rc.Bottom)
taskbarLocation = TaskbarLocation.Left;
if (rc.Right > rc.Bottom)
taskbarLocation = TaskbarLocation.Top;
}
if (rc.X > rc.Y)
taskbarLocation = TaskbarLocation.Right;
if (rc.X < rc.Y)
taskbarLocation = TaskbarLocation.Bottom;
}

public static Rectangle GetTaskbarPosition() {
var data = new APPBARDATA();
data.cbSize = System.Runtime.InteropServices.Marshal.SizeOf(data);
IntPtr retval = SHAppBarMessage(ABM_GETTASKBARPOS, ref data);
if (retval == IntPtr.Zero) throw new Win32Exception("Please re-install Windows");
return new Rectangle(data.rc.left, data.rc.top,
data.rc.right - data.rc.left, data.rc.bottom - data.rc.top);
}
// P/Invoke goo:
private const int ABM_GETTASKBARPOS = 5;
[System.Runtime.InteropServices.DllImport("shell32.dll")]
private static extern IntPtr SHAppBarMessage(int msg, ref APPBARDATA data);
private struct APPBARDATA {
public int cbSize;
public IntPtr hWnd;
public int uCallbackMessage;
public int uEdge;
public RECT rc;
public IntPtr lParam;
}
private struct RECT {
public int left, top, right, bottom;
}

SHAppBarMessage(ABM_GETTASKBARPOS)
See the SHAppBarMessageFunction and the ABM_GETTASKBARPOSMessage for more info and the pinvoke page for SHAppBarMessagehas a VB.Net sample that shouldn't be too difficult to translate.
见SHAppBarMessage功能和ABM_GETTASKBARPOS消息更多的信息和PInvoke的页面SHAppBarMessage具有不应该太难翻译了VB.Net样品。

The SHAppBarMessagefunction will return you information about the taskbar if you pass in the ABM_GETTASKBARPOSmessage. It has an out parameter which is a pointer to APPBARDATAthat contains the screen cooridinates of the task bar. You can use to work out where on screen it is.
如果您传入ABM_GETTASKBARPOS消息，SHAppBarMessage函数将返回有关任务栏的信息。它有一个 out 参数，它是一个指向包含任务栏屏幕坐标的 APPBARDATA的指针。您可以使用它来计算它在屏幕上的位置。

It's probably best to use the available API: NotifyIcon.ShowBalloonTip:
最好使用可用的 API: NotifyIcon.ShowBalloonTip:
void Form1_DoubleClick(object sender, EventArgs e)
{
notifyIcon1.Visible = true;
notifyIcon1.ShowBalloonTip(20000, "Information", "This is the text",
ToolTipIcon.Info );
}

In Java, using JNA (adapted from other C# solutions above)
在 Java 中，使用 JNA（改编自上述其他 C# 解决方案）
public static Rectangle getTaskbarPosition() throws Exception {
APPBARDATA data = new APPBARDATA();
data.cbSize = new WinDef.DWORD(data.size());
WinDef.UINT_PTR retval = Shell32.INSTANCE.SHAppBarMessage(ABM_GETTASKBARPOS, data);
if (retval == null) {
throw new Exception("Please re-install Windows");
}
return new Rectangle(data.rc.left, data.rc.top, data.rc.right - data.rc.left, data.rc.bottom - data.rc.top);
}
