C#如何从IntPtr获取Byte [] [英] C# how to get Byte[] from IntPtr

问题描述

我有一个具有委托的.dll(不是我自己的).该委托回调函数为:
"CallBackFN(ushort opCOde， IntPtr有效负载，uint大小，uint localIP)"

I have a .dll(not my own) that has a delegate. This delegate Callback function is:
"CallBackFN(ushort opCOde, IntPtr payload, uint size, uint localIP)"

如何将IntPtr转换为Byte []?我认为有效负载实际上是Byte [].如果不是Byte []而是其他东西，我会丢失一些数据吗?

How can i convert IntPtr to Byte[]? I think that payload is actually Byte[]. If it's not Byte[] and it's something else would i lose some data?
