昨天搞了半天用TClientSocket和TServerSocket传文件怎么老是大小不一致呢？

谁做过吗?可以指教一下吗？谢谢了睡觉了..,...

我建议你真要穿文件还是用别的控件
这两个控件总是出问题

来试试TMemoryStream对象，我使用它传输文件一切ok

TWinSocketStream *pStream = new TWinSocketStream(ClientSocket1->Socket,60000);
TMemoryStream *pms = new TMemoryStream();

发送文件：
try
{
memset(ReturnBuffer,0,sizeof(ReturnBuffer));
ReturnBuffer[0]=0x02;
//文件报头
ReturnBuffer[HEADSIZE+2]=0x7f;
//加载文件
pms->LoadFromFile(ReturnFullFileName);
//写文件名及传输文件大小
memset(ReturnBuffer+HEADSIZE+3,' ',FILENAME+FILESIZE);
memcpy(ReturnBuffer+HEADSIZE+3,ReturnFileName,strlen(ReturnFileName));
memcpy(ReturnBuffer+HEADSIZE+3+FILENAME,IntToStr(pms->Size).c_str(),strlen(IntToStr(pms->Size).c_str()));
pms->ReadBuffer(ReturnBuffer+HEADSIZE+3+FILENAME+FILESIZE,pms->Size);
ReturnBuffer[HEADSIZE+3+FILENAME+FILESIZE+pms->Size]='\0';
//传输数据
pStream->Write(ReturnBuffer,HEADSIZE+3+FILENAME+FILESIZE+pms->Size);
}


接收文件：
pms->Position = 0;
pms->WriteBuffer(buffer+报头字节,StrToInt(文件大小));
pms->SaveToFile(WriteFileName);

先读出来，然后传递，最后写到文件中去

我是这样写的
FILE *tReadStream=fopen("","rb");

然后
传的时候，先传文件名，以及文件的大小

在接受方接收到文件名以后
char t_Buffer[MAX_LENGTH];
FILE *tWriteStream=fopen("","wb+");
long t_FileLength;

while(t_FileLength)
{
//循环接受
int t_ReciveLength=...
fwrite(t_Buffer,1,t_ReciveLength,tWriteStream);
t_FileLength-=t_ReciveLength;
}
