这段代码展示了一个用C#实现的读取文件数据的功能。定义了ReadPointFile方法，通过StreamReader读取指定路径文件内容，将每行数据处理后存储到List中，再将每行数据按逗号分割，转换为PointD对象添加到knownPoints列表，最后关闭读取器。

#region 读取数据
        public void ReadPointFile(string path, out List<PointD> knownPoints)
        {
            StreamReader sr = new StreamReader(path);
            List<string> lines = new List<string>();
            string line = sr.ReadLine();
            while (line != null && line != " ")
            {
                line.Replace(" ", "");
                lines.Add(line);
                line = sr.ReadLine();
            }
            knownPoints = new List<PointD>();
            for (int i = 0; i < lines.Count; i++)
            {
                PointD point = new PointD();
                string[] str = lines[i].Split(',', '，');
                point.pointName = str[0];
                point.X =Convert.ToDouble(str[1]);
                point.Y = Convert.ToDouble(str[2]);
                knownPoints.Add(point);
            }
            sr.Close();
        }
