c#从txt读取数据填入datatable

从TXT读取并存入到DataTable

从TXT读取并存入到DataTable的代码，以逗号为分割符，TXT中的数据例如：

————————

1,105.64,38.65

2,106.05,38.72

————————

static void Main(string[] args)

        {

            #region 读取字符串

            StreamReader sr = new StreamReader("c:\\bb.txt", Encoding.GetEncoding("GB2312"));

            string txt = sr.ReadToEnd().Replace("\r\n","-");

            string[] nodes = txt.Split('-');

            #endregion

            #region 填充DataTable

            DataTable dt = new DataTable();

            dt.Columns.Add("ID", typeof(int));

            dt.Columns.Add("Field1", typeof(double));

            dt.Columns.Add("Field2", typeof(double));

            foreach (string node in nodes)

            {

                string[] strs = node.Split(',');

                DataRow dr = dt.NewRow();

                dr["ID"] = strs[0];

                dr["Field1"] = strs[1];

                dr["Field2"] = strs[2];

                dt.Rows.Add(dr);

            }

            #endregion

            sr.Close();

        }

------解决方案--------------------

DataTable dt = new DataTable();

		dt.Columns.Add("id", typeof(int));

		dt.Columns.Add("经度", typeof(double));

		dt.Columns.Add("纬度", typeof(double));

		string[] rows = File.ReadAllLines(@"c\test.txt"));

		foreach (string row in rows)

			dt.Rows.Add(row.Split(','));

		dataGridView1.DataSource = dt;
