the code below is part of what I use to read data from an xml file and draw graphics on the screen for hurricane points.

 MapPoint mp = new MapPoint(xLoc, yLoc, new SpatialReference(4326));
                Graphic gPt = new Graphic();
                gPt.Geometry = mp;

                gPt.Attributes.Add("Storm", ptVals[6]);
                gPt.Attributes.Add("Model", ptVals[0]);
                gPt.Attributes.Add("Time", ptVals[1]);
                gPt.Attributes.Add("Lat", ptVals[2]);
                gPt.Attributes.Add("Lon", ptVals[3]);
                gPt.Attributes.Add("Wind", ptVals[4]);
                gPt.Attributes.Add("Pressure", ptVals[5]);

                gPt.Symbol = gSym;
                gl.Graphics.Add(gPt);

to read from a text file you would need to get the file from the user with the OpenFileDialog. I use the xml format and WebClient to get at the data.
