I fix it, I added the line in blue, This works perfect for me

foreach (DateTime op in Records.Keys)
      {
        CodeRecords[op].Records = new List();
        foreach (var Rec in FilteredList)
        {
          Row = new TempEvent();
          Row.eIndex = ++Index;
          Row.code = C.code;
          Row.LSW = Rec.ELSW;
          Row.MSW = Rec.EMSW;
          Row.eValue = Rec.Data;
          CodeRecords[op].Records.Add(Row);
          if (Rec.code == "E000" && Rec.Data[0] == 'F')//End of operation
          {
            CodeRecords[op].EventCount = ++NumOfEvents;
            NumOfEvents = 0;
            Index = 0;
          }
          else
          {
            ++NumOfEvents;
          }
        }
            FilteredList.RemoveRange(Index, EventRow.eIndex);
      }

after breaking out of the second foreach how to enumerate through the remaining events instead of starting over

lets say I have a total of 10 rows in the second foreach,
and I breakout of the foreach at row 3, I have seven rows left,

the question is when i come back around to the second foreach, I want start from row 4, instead of row [0], thats the problem im having

im already do that in the code sniippets above

what I leave this case below can come back around to the second foreach its starts all over

if (Rec.code == "E000" && Rec.Data[0] == 'F')//End of operation
          {
            CodeRecords[op].EventCount = ++NumOfEvents;
            NumOfEvents = 0;
            Index = 0;

          }

refe example...
     string Rec;
     foreach (DateTime op in Records.Keys)
      {
        CodeRecords[op].Records = new List();
        foreach (Rec in FilteredList)
        { }
      }

i tried doing this below the second foreach still starts all over when it get into the , becaue its multiple of the,
          if (Rec.code == "E000" && Rec.Data[0] == 'F')//End of operation te second foreach has 513 events, I cant make it pass the first 123 events because the second foreach

foreach (DateTime op in Records.Keys)
      {
        CodeRecords[op].Records = new List();
        foreach (var Rec in FilteredList)
        {

          if (EventRecords.Equals(EventRec))
          {
            continue;
          }
          Row = new TempEvent();
          Row.eIndex = ++Index;
          Row.code = C.code;
          Row.LSW = Rec.ELSW;
          Row.MSW = Rec.EMSW;
          Row.eValue = Rec.Data;
          CodeRecords[op].Records.Add(Row);
          if (Rec.code == "E000" && Rec.Data[0] == 'F')//End of operation
          {
            CodeRecords[op].EventCount = ++NumOfEvents;
            NumOfEvents = 0;
            Index = 0;
           break;
          }
          else
          {
            ++NumOfEvents;
          }
        }
      }

can you spell it out alot lil bit more, I think i know where you going, i just want to be sure

for example object Rec = 0

first for-each

second for-each

foreach(Rec in ...)

I think can problem check for the unique record id I gave i added, and if the unique record ID exists, continue , that might work, what do you think

ok I had the break in the wrong spot, so yeah your solution works, what about the second foreach, the second foreach im enumerating and adding records to the key records,
so if it come back to the second foreach its going to start all back over, how to remember the last location and start from that point

David Smith16y ago
i already tried that, what it does is start the froeach from the beginning instead of going to the next key, so this is where im lost

Put a break statement after the line Index = 0;
It will break the current for loop and move the cursor over to the first foreach loop.
Hope that will solve your problem
