为什么“[DllImport]”的入口点为“RtlSecureZeroMemory”时会失败,即使它是一个有很好文档记录的入口点?

SecureZeroMemory ,使用下面的代码失败,错误为 System.EntryPointNotFoundException -尽管有很好的记录 here, on PInvoke ,和 here, on SO . 在目标.NET Framework 4.7.2上运行完全正常的Windows 10 Pro。

        /// <summary>
        /// A kernel32 function that destroys all values in a block of memory
        /// </summary>
        /// <param name="destination">The pointer to the start of the block to be zeroed</param>
        /// <param name="length">The number of bytes to zero</param>
        /// <returns></returns>
        [DllImport("kernel32.dll", CharSet = CharSet.Auto, EntryPoint = "RtlSecureZeroMemory")]
        public static extern void SecureZeroMemory(IntPtr destination, IntPtr length);
