C # get current cursor icon

Question

I tried to do this and could not do this, this is what I got:

[DllImport("user32.dll")]
static extern bool SetSystemCursor(IntPtr hcur, uint id);

[DllImport("user32.dll", EntryPoint = "GetCursorInfo")]
public static extern bool GetCursorInfo(out CURSORINFO pci);

[DllImport("user32.dll", EntryPoint = "CopyIcon")]
public static extern IntPtr CopyIcon(IntPtr hIcon);

[StructLayout(LayoutKind.Sequential)]
public struct CURSORINFO
{
    public Int32 cbSize;        // Specifies the size, in bytes, of the structure. 
    public Int32 flags;         // Specifies the cursor state. This parameter can be one of the following values:
    public IntPtr hCursor;          // Handle to the cursor. 
    public POINT ptScreenPos;       // A POINT structure that receives the screen coordinates of the cursor. 
}

public void etc()
{
    IntPtr hwndic = new IntPtr();
    CURSORINFO curin = new CURSORINFO();
    curin.cbSize = Marshal.SizeOf(curin);
    if (GetCursorInfo(out curin))
    {
        if (curin.flags == CURSOR_SHOWING)
        {
            hwndic = CopyIcon(curin.hCursor);
            SetSystemCursor(hwndic, OCR_NORMAL);
        }
    }
}

The problem is that the copied icon sometimes differs from the default mouse icon if it catches it waiting, for example, then it can give me a mouse wait icon.

I want to get the default cursor icon (idle icon) of the running system, how can I do this?

Thanks in advance.

I solved my problems, after some research, I got something interesting that is likely to work all the time.

Instead of trying to save the cursor icon and load it, I thought of another idea.

[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern Int32 SystemParametersInfo(UInt32 uiAction,UInt32 uiParam, String pvParam, UInt32 fWinIni);

msdn, - , "SPI_SETCURSORS (0x57)", :

" . uiParam , pvParam - NULL."

, , , :

[DllImport("User32.dll", CharSet = CharSet.Ansi, BestFitMapping = false, ThrowOnUnmappableChar = true)]
private static extern IntPtr LoadCursorFromFile(String str);

uint SPI_SETCURSORS = 0x57;
var NewArrow = LoadCursorFromFile("C:\\Users\\mtnju\\Downloads\\invisible.cur"); // loads some new cursor icon using the LoadCursorFromFile function
SetSystemCursor(NewArrow, OCR_NORMAL); // sets the new cursor icon using the SetSystemCursor function
SystemParametersInfo(SPI_SETCURSORS, 0, null, 0);// reloads all of the system cursors
