看了很多txt转文本的，但是都没啥效果，自己写了一个

  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;}
