我创建了一个应用程序,但我对焦点有疑问。如何在表单加载时禁用其他主窗体的焦点?

WPF表单具有ShowActivated属性。将此设置为false,表单将无法获得焦点。
您也可以覆盖OnActivated方法:
protected override void OnActivated(EventArgs e)
{
base.OnActivated(e);
//Set the window style to noactivate.
WindowInteropHelper helper = new WindowInteropHelper(this);
SetWindowLong(helper.Handle, GWL_EXSTYLE,
GetWindowLong(helper.Handle, GWL_EXSTYLE) | WS_EX_NOACTIVATE);
}
private const int GWL_EXSTYLE = -20;
private const int WS_EX_NOACTIVATE = 0x08000000;
[DllImport("user32.dll")]
public static extern IntPtr SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);
[DllImport("user32.dll")]
public static extern int GetWindowLong(IntPtr hWnd, int nIndex);
