class TXTWriter
{
    public TXTWriter(DataSet myData, String Path)
    {
        StreamWriter sw = new StreamWriter(Path, false, Encoding.UTF8);
        String DataRow = "";
        for (int i = 0; i < myData.Tables[0].Columns.Count; i++) //获取列名
        {
            DataRow += myData.Tables[0].Columns[i].ColumnName;
            if (i < myData.Tables[0].Columns.Count - 1) DataRow += " ";
        }
        sw.WriteLine(DataRow);
        for (int i = 0; i < myData.Tables[0].Rows.Count; i++) //获取数据
        {
            DataRow = "";
            for (int j = 0; j < myData.Tables[0].Columns.Count; j++)
            {
                DataRow += myData.Tables[0].Rows[i][j].ToString();
                if (j < myData.Tables[0].Columns.Count - 1) DataRow += " ";
            }
            sw.WriteLine(DataRow);
        }
        sw.Close();
    }
