xml标准格式是这样的： <?xml version="1.0" standalone="yes"?> <VoucherSet> 　　<Voucher> 　　　　<segment>会员卡</segment> 　　　　<payment>现金</payment> 　　　　<summary>1</summary> 　　　　<subjectType>现金</subjectType> 　　　　<subject>1</subject> 　　　　<memo>1</memo> 　　</Voucher> </VoucherSet> 代码生成后： <?xml version="1.0" standalone="yes"?> <DocumentElement> <Voucher> <segment>会员卡</segment> <payment>现金</payment> <summary>1</summary> <subjectType>现金</subjectType> <subject>1</subject> <memo>1</memo> </Voucher> </DocumentElement> 对于这个<DocumentElement>我应该如何设置？？？ C#代码如下： DataTable dt = new DataTable("Voucher"); dt.Columns.Add(new DataColumn("segment")); dt.Columns.Add(new DataColumn("payment")); dt.Columns.Add(new DataColumn("summary")); dt.Columns.Add(new DataColumn("subjectType")); dt.Columns.Add(new DataColumn("subject")); dt.Columns.Add(new DataColumn("memo")); int count = this.dgvVoucherSet.Rows.Count -1; //取到 凭证设置 行数(-1:去掉空行) for (int i = 0; i < count; i++) { string segment = dgvVoucherSet.Rows[i].Cells["segment"].Value.ToString(); //业务分类 string payment = dgvVoucherSet.Rows[i].Cells["payment"].Value.ToString(); //支付方式 string summary = dgvVoucherSet.Rows[i].Cells["summary"].Value.ToString(); //摘要 string subjectType = dgvVoucherSet.Rows[i].Cells["subjectType"].Value.ToString(); //科目类型 string subject = dgvVoucherSet.Rows[i].Cells["subject"].Value.ToString(); //会计科目 string memo = dgvVoucherSet.Rows[i].Cells["memo"].Value.ToString(); //备注 DataRow dr = dt.NewRow(); dr["segment"] = segment; dr["payment"] = payment; dr["summary"] = summary; dr["subjectType"] = subjectType; dr["subject"] = subject; dr["memo"] = memo; dt.Rows.Add(dr); } dt.WriteXml(GetXmlFullPath(xmlName)); 急啊，大家快帮帮忙吧！
