RRDTool for C# (port of [jrobin.org] 1.5.14)

Creating rrd files and updates values is working fine, the graph part still need some works.

API is NOT yet stable, but it should not change a lot before v 1.0

Example :

RrdDef def = new RrdDef(SAMPLE);
def.StartTime = 920804400;
def.AddDatasource(DsDef.FromRrdToolString("DS:speed:COUNTER:600:U:U"));
def.AddArchive(ArcDef.FromRrdToolString("RRA:AVERAGE:0.5:1:24"));
def.AddArchive(ArcDef.FromRrdToolString("RRA:AVERAGE:0.5:6:10"));

using (RrdDb db = RrdDb.Create(def))
{
    Sample sample = db.CreateSample();
    sample.SetAndUpdate("920804700:12345", "920805000:12357", "920805300:12363");
    sample.SetAndUpdate("920805600:12363", "920805900:12363 ", "920806200:12373");
    sample.SetAndUpdate("920806500:12383", "920806800:12393", "920807100:12399");
    sample.SetAndUpdate("920807400:12405", "920807700:12411", "920808000:12415");
    sample.SetAndUpdate("920808300:12420", "920808600:12422", "920808900:12423");

    FetchRequest req = db.CreateFetchRequest(ConsolidationFunction.AVERAGE, 920804400, 920809200);
    FetchData data = db.FetchData(req);
    
    //Use data to retrieve values...
}
