紧急：Unix / Windows Struct转换问题 [英] URGENT: Unix/Windows Struct cast problem

问题描述

Follwing结构：

[StructLayout（LayoutKind.Sequential，Pack = 1，CharSet = CharSet.Ansi）]


public struct TpSomeMsgRep


{


public uint SomeId;


[MarshalAs（UnmanagedType.ByValArray，SizeConst = 2） ]


public Byte [] notinuse1;


[MarshalAs（UnmanagedType.ByValArray，SizeConst = 674）]

>
public Byte [] theMainPart;


}


用于从缓冲区转换，由TCP从C ++程序收到，像这样：


oMsgRes =（mm.TpSomeMsgRep）SomeBuffer;


这对Unix服务器来说很好用。一旦转移到Windows我就无法投射到结构。


请帮助帮助帮助！

您想要dot.NET吗？只需询问：

"请， www.dotnet.us

Follwing the struct:
[StructLayout(LayoutKind.Sequential, Pack=1, CharSet=CharSet.Ansi)]

public struct TpSomeMsgRep

{

public uint SomeId;

[MarshalAs(UnmanagedType.ByValArray, SizeConst=2)]

public Byte[] notinuse1;

[MarshalAs(UnmanagedType.ByValArray, SizeConst=674)]

public Byte[] theMainPart;

}

This used to cast from buffer, recieved by TCP from C++ Program, like this:

oMsgRes= (mm.TpSomeMsgRep )SomeBuffer;

This work fine with Unix server. once transfer to Windows I can not cast to
the structure.

PLEASE HELP HELP HELP!

推荐答案

如果您能提供代码如何收到

包，那将会很棒在C＃所以我们可以看到如何帮助你。

Would be great if you could provide the code how you are receiving the
packets in C# so we can see how to help you.

代码看起来像普通的异步TCP客户端

如果要将字节数组转换为

结构，你必须使用编组功能：


byte [] buf = *收到*;

GCHandle h = GCHandle.Alloc（buf，GCHandleType.Pinned）;

TpSomeMsgRep rep =（ TpSomeMsgRep）Marshal.PtrToStruct（h.AddrOfPinnedOb ject（），

typeof（TpSomeMsgRep））;

h.Free（）;

/ /使用代表

如果您需要别的东西，请更具体。


HTH，

问候

What and how are you casting, if you want to cast a byte array to your
struct, you must use marshalling functionality:

byte [] buf = * received * ;
GCHandle h = GCHandle.Alloc( buf, GCHandleType.Pinned );
TpSomeMsgRep rep = (TpSomeMsgRep)Marshal.PtrToStruct(h.AddrOfPinnedOb ject(),
typeof(TpSomeMsgRep));
h.Free();
// use rep
If you need something else, be more specific.

HTH,
greetings
