GetMenuString (user32)
.
C# Signature:
[DllImport("user32.dll")]
static extern int GetMenuString(IntPtr hMenu, uint uIDItem,
[Out,MarshalAs(UnmanagedType.LPStr)] StringBuilder lpString, int nMaxCount, uint uFlag);
in Specifies the menu item to be changed, as determined by the uFlag parameter.
lpString
out Pointer to the buffer that receives the NULL-terminated string. If the string is as long or longer than lpString, the string is truncated and the terminating NULL character is added. If lpString is NULL, the function returns the length of the menu string.
nMaxCount
in Specifies the maximum length, in characters, of the string to be copied. If the string is longer than the maximum specified in the nMaxCount parameter, the extra characters are truncated. If nMaxCount is 0, the function returns the length of the menu string.
uFlag
in Specifies how the uIDItem parameter is interpreted. This parameter must be one of the following values.
MF_BYCOMMAND
Indicates that uIDItem gives the identifier of the menu item. If neither the MF_BYCOMMAND nor MF_BYPOSITION flag is specified, the MF_BYCOMMAND flag is the default flag.
MF_BYPOSITION
Indicates that uIDItem gives the zero-based relative position of the menu item.
IntPtr hMenu = GetMenu(hWnd);
if (hMenu.ToInt32() != 0)
{
for (uint i = GetMenuItemCount(hMenu) - 1; i >= 0; i--)
{
StringBuilder menuName = new StringBuilder(0x20);
GetMenuString(hMenu, i, menuName, 0x20, MF_BYPOSITION);
DeleteMenu(hMenu, i, MF_BYPOSITION);
}
}
}

An IntPtr is a pointer to a memory location (unmanaged) that adapts to the platform it is running on (64-bit, etc.) UNLIKE a standard int/Integer. You should always use this type for unmanaged calls that require it, even though an int will appear to work on your development machine.
