C#实现DataTable转TXT文件

实现datatable转txt文件代码如下：

 public executionresult datatabletotxt(datatable vcontent, string voutputfilepath)
        {
            executionresult sresult = new executionresult();
            stringbuilder stxtcontent;

            try
            {
                if (file.exists(voutputfilepath))
                    file.delete(voutputfilepath);

                stxtcontent = new stringbuilder();
               
                //数据
                foreach (datarow row in vcontent.rows)
                {
                    for (int i = 0; i < vcontent.columns.count; i++)
                    {
                        stxtcontent.append(row[i].tostring().trim());
                        stxtcontent.append(i == vcontent.columns.count - 1 ? "\r\n" : "\t");
                    }
                }
                file.writealltext(voutputfilepath, stxtcontent.tostring(), encoding.unicode);
                sresult.status = true;
            }
            catch (exception ex)
            {
                sresult.message = ex.message;
                sresult.status = false;
            }
            return sresult;
        }
