从Socket接收数据时出现乱码字节偏移 [英] garbled byte offset when receiving data from Socket
问题描述
我有一个C＃程序，它通过
套接字以字节数组发送数据。
VC ++应用服务器以下列格式接收数据....
typedef struct advice
{
header sHdr;
char code [ 33];
char pn [11];
char州[4];
char szType [4];
char szTravelDate [9];
char szAmount [13];
char szMethod [7];
char CATID [16] ;
长lStan;
...
}
奇怪的部分是每一个lStan失踪后的char数组3
字符。
如果我在VC ++中执行QUICKWATCH，我将lStan的值改为1128415488。
将其转换为字节数组，产生字节{0,65,66,67} -
是lStan之后字段的前3个值。（字段在lStan之后
有''ABCDEF''）
i CANT使用任何结构，ma因为我的结构定义来自XML Schema文档，因此我认为我的结构定义来自于一个XML Schema文档。
C＃中的值的转换例程
int nData = int.Parse（strTempData）;
//转换为字节数组; this.bPvtData =
BitConverter.GetBytes（nData）;
将3652转换为字节数组= {68,14,0,0}
当它从
套接字出来时显然正在发生这种情况......或者VC ++没有解释
''的大小long''变量（我作为Int32传递）
请帮忙！
< blockquote>一个long是一个Int64，根据文档：
类型范围大小.NET Framework类型
长a ?? 9,223,372,036,854,775,808到9,223,372,036,854,775,807签名64位
整数System.Int64
希望有所帮助:)

感谢马克...但实际上我确实考虑过这个事实并且正在使用
a Int32在C＃结束，
，因为我的VC ++ long（int）是一个32位整数。

这听起来像CATID那样导致了问题。你好吗
传输那个？

i have a C# program that is sending data in a byte array through a
socket.
the VC++ application server receives data in teh following format....
typedef struct advice
{
header sHdr;
char Code[33];
char pn[11];
char State[4];
char szType[4];
char szTravelDate[9];
char szAmount[13];
char szMethod[7];
char CATID[16];
long lStan;
...
}
the weird part is that EVERY char array after lStan is missing 3
characters.
if i do a QUICKWATCH in VC++, i get the value of lStan as "1128415488".
converting this to a byte array , yields the bytes {0,65,66,67} - which
is the first 3 values of the field after lStan.(the field after lStan
has ''ABCDEF'')
i CANT use any structures, marshalled or otherwise at the C# end ,
because my structure definitions come out of a XML Schema document.
conversion routine for the value in C#
int nData = int.Parse(strTempData);
//convert to Byte Array; this.bPvtData =
BitConverter.GetBytes(nData);
this converts 3652 into byte array = {68,14, 0 , 0}
something is evidently happening to this when it comes out of the
Socket ... either that or VC++ is not interpreting the size of the
''long'' variable (which im passing as a Int32)
please help!
A long is a Int64, as per documentation:
Type Range Size .NET Framework type
long a??9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 Signed 64-bit
integer System.Int64
Hope that helps :)

thanks a ton Mark... but actually i did consider that fact and am using
a Int32 at C# end,
because my VC++ long (int) is a 32-bit Integer.

It sounds like it''s CATID that''s causing the problem then. How are you
transmitting that?
