C# txt文本转DataTable

看了很多txt转DataTable的，但是都没啥效果，自己写了一个
实现的效果是：每一列数据为一列DataColumn DataTable表头中含有字段名。

  public DataTable TXT2DataTable(string path)
        {
            try
            {
                StreamReader sR = File.OpenText(path);
                DataTable dt = new DataTable();
                string firstLine = sR.ReadLine();
                string[] colName = firstLine.Split('\t');
                foreach (var i in colName)
                {
                    DataColumn col = dt.Columns.Add(i.ToString());
                }
                string nextLine;
                while ((nextLine = sR.ReadLine()) != null)
                {
                    string[] every_row = nextLine.Split('\t');
                    DataRow dr = dt.NewRow();
                    for (int i = 0; i < dt.Columns.Count; i++)
                    {
                        dr[i] = every_row[i];
                    }
                    dt.Rows.Add(dr);
                }
                sR.Close();
                return dt;
            }
            catch (Exception ex)
            {
                XtraMessageBox.Show("数据格式错误！","提示：",MessageBoxButtons.OK,MessageBoxIcon.Warning);
                return null;
            }
