以EventLogEntryCollection的Count方式来进行计数，发现最新日志数量比第一次读取的日志数量多了就顺序读取，少了则代表日志重置，从新读取
while (1)
{
//应用日志实时读取
log->Log = ("Application");
EventLogEntryCollection^ myApplication = log->Entries;
if (myApplication->Count > AppliNum) //如有新日志，则按序输出
{
const char* Message = (const char*)(Marshal::StringToCoTaskMemAnsi(myApplication[AppliNum]->Message)).ToPointer();
const char* TimeWritten = (const char*)(Marshal::StringToCoTaskMemAnsi(myApplication[AppliNum]->TimeWritten.ToString())).ToPointer();
string Msg = Message;
string Time = TimeWritten;
Client(Time, Msg);
AppliNum++;
}
else if (myApplication->Count < AppliNum) //表示日志以重置
{
for each (EventLogEntry^ var in myApplication)
{
const char* Message = (const char*)(Marshal::StringToCoTaskMemAnsi(var->Message)).ToPointer();
const char* TimeWritten = (const char*)(Marshal::StringToCoTaskMemAnsi(var->TimeWritten.ToString())).ToPointer();
string Msg = Message;
string Time = TimeWritten;
Client(Time, Msg);
}
AppliNum = myApplication->Count;
}
}
