您当前的位置: 客户端以字节数组形式发送一个结构以后，服务器无法正确读出内容，不知道问题出在哪里
客户端发送
userInfo aUser;
aUser.name=Edit1->Text;
aUser.passWord=Edit2->Text;
TBytes buffer;
buffer=RawToBytes(&aUser, sizeof(userInfo));
IdTCPClient1->IOHandler->Write(buffer);
服务器端接收
userInfo aUser;
TBytes buffer;
try
{
AContext->Connection->IOHandler->ReadBytes(buffer, sizeof(userInfo), false);
BytesToRaw(buffer, &aUser, sizeof(userInfo));
Memo1->Lines->Add("用户名："+aUser.name);
Memo1->Lines->Add("密码："+aUser.passWord);
}
catch (Exception &e)
{
Memo1->Lines->Add("读取登录信息异常");
return;
}
