.NET - 从非托管数组非托管数组复制
问题描述：
我一直在寻找通过Marshal类，但我似乎无法找到一种方法，让我从一个非托管阵列（IntPtr的）复制到其他非托管阵列（IntPtr的）。
I've been looking through the Marshal class, but I can't seem to find a method that allows me to copy from an unmanaged array (IntPtr) to another unmanaged array (IntPtr).
这是使用.NET可能吗？
Is this possible using .NET?
答
您还可以的DllImport RtlMoveMemory来完成这项工作：
You can also DllImport RtlMoveMemory to get the job done:
[DllImport("Kernel32.dll", EntryPoint="RtlMoveMemory", SetLastError=false)]
static extern void MoveMemory(IntPtr dest, IntPtr src, int size);
这也将需要FullTrust的，但是，但是当你正在使用非托管code，我希望你已经拥有了它。
This will also require FullTrust, however, but as you are working with unmanaged code, I'd expect you already have it.
