如何将System.Windows.Window设置为System.Windows.Forms.Form的所有者？

在我搜索了一段时间后才意识到我已经在我的一个utils类中得到了答案，我决定将答案放在stackoverflow上。希望有人觉得这很有用。

Answer 1

使用此方法：

[DllImport("user32.dll")]

private static extern int SetWindowLong(HandleRef hWnd, int nIndex, int dwNewLong);

/// <summary>
/// sets the owner of a System.Windows.Forms.Form to a System.Windows.Window
/// </summary>
/// <param name="form"></param>
/// <param name="owner"></param>
public static void SetOwner(System.Windows.Forms.Form form, System.Windows.Window owner)
{
    WindowInteropHelper helper = new WindowInteropHelper(owner);
    SetWindowLong(new HandleRef(form, form.Handle), -8, helper.Handle.ToInt32());
}

Answer 2

SetParent {-1}} SetWindowLong与GWL_HWDPARENT相比，[DllImport("user32.dll", SetLastError = true)] static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);被认为“更正确”吗？
