例子:

- {
- StreamReader sr = new StreamReader(this.FileName, System.Text.Encoding.UTF8);
- List<string[]> dataList = new List<string[]>();
- sr.ReadLine();
- string line = sr.ReadLine();
- while (line != null)
- {
- if (line == String.Empty)
- {
- line = sr.ReadLine();
- continue;
- }
- dataList.Add(line.Split(','));
- line = sr.ReadLine();
- }
- sr.Close();
- StationData stationData = new StationData();
- List<string> stations = new List<string>();
- string stName;
- int i;
- double lon, lat;
- double t;
- t = 0;
- string[] dataArray;
- double[,] DiscreteData = new double[3, dataList.Count];
- double minX, maxX, minY, maxY;
- minX = 0;
- maxX = 0;
- minY = 0;
- maxY = 0;
- //Get real variable index
- int varIdx1 = FieldList.IndexOf(this.Variables[varIdx].Name);
- String vstr;
- for (i = 0; i < dataList.Count; i++)
- {
- dataArray = dataList[i];
- stName = dataArray[0];
- lon = double.Parse(dataArray[1]);
- lat = double.Parse(dataArray[2]);
- vstr = dataArray[varIdx1];
- if (String.IsNullOrEmpty(vstr))
- t = stationData.MissingValue;
- else
- t = double.Parse(dataArray[varIdx1]);
- //if (lon < 0)
- //{
- // lon += 360;
- //}
- //Initialize data
- DiscreteData[0, i] = lon;
- DiscreteData[1, i] = lat;
