请教：EventLog读出后，如何对某Entry排序呢？

Question

void BindGrid()
{
EventLog aLog=new EventLog();
aLog.Log="Application";
aLog.MachineName=".";LogGrid.DataSource=aLog.Entries;
LogGrid.DataBind();
}

Answer 1

UPvoid BindGrid()
{
EventLog aLog=new EventLog();
aLog.Log="Application";
aLog.MachineName=".";//现在这，比如对Index排序，如何写,或给个思路。谢了LogGrid.DataSource=aLog.Entries;
LogGrid.DataBind();
}

Answer 2

write a custom IComparer, seehttp://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemcollectionsicomparerclasscomparetopic.asp(didn't test, so there might be errors):public class YourCustomComparer : IComparer
{
  public int Compare(object x,object y)
  {
EventLogEntry a = (EventLogEntry)x;
EventLogEntry b = (EventLogEntry)y; return a.Index - b.Index;
  }
}EventLogEntryCollection ec = aLog.Entries;
EventLogEntry[] ees = new EventLogEntry[ec.Count];
ec.CopyTo(ees,0);Array.Sort(ees, new YourCustomComparer());LogGrid.DataSource = ees;
