[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool GetWindowRect(HandleRef hWnd, out RECT lpRect);

[StructLayout(LayoutKind.Sequential)]
public struct RECT
{
    public int Left;        // x position of upper-left corner
    public int Top;         // y position of upper-left corner
    public int Right;       // x position of lower-right corner
    public int Bottom;      // y position of lower-right corner
}

foreach (Process pr in Process.GetProcesses())
{
    RECT rc;
    GetWindowRect(???, out rc);

我该怎么做"???"？.它告诉我我必须放置一个HandleRef对象,但我不知道如何从Process方法获取HandleRef对象.
