最近的项目在做socket通信报文解析的时候,用到了结构体与字节数组的转换:由于客户端采用C++开发,服务端采用C#开发,所以双方必须保证各自定义结构体成员类型和长度一致才能保证报文解析的正确性,这一点非常重要. 首先是结构体定义,一些基本的数据类型,C#与C++都是可以匹配的: [StructLayoutAttribute(LayoutKind.Sequential, CharSet = CharSet.Ansi, Pack = )] public struct Head { public u
补充过程中~ 感觉应该是C#调用非托管的比较专门的class 例1. public struct ImageDataMsg { public char DataType; public int Srv_index; public char ConvertType; //这个个地方要指定长度,这样就可以的德奥结构体的正确长度了 [MarshalAs(UnmanagedType.ByValArray, SizeConst = 10)] public int[] VecLayer;//需要那几个图层.
原文:Marshal UTF8 Strings in .NET Marshal UTF8 Strings in .NET Wow, what a pain in the butt. .NET strings are stored internally as UTF16, not UTF8, so if you're marshaling strings to and from a library that wants strings as UTF8, you have to manually m
