C# 基于orderid保存单独的xml文件

您好，所有当前我已将所有xml文件保存在一个文件中。但我需要另存一个文件。你能帮我一下吗

当前代码：-

 System.Data.DataTable checkFile = new System.Data.DataTable();
                sql = "sql";
                DBCon clsDB = new DBCon(SAPCompanySettings.MSSQLConnectionString);
                clsDB.Execute(sql, ref checkFile);                
            var stringwriter = new StringWriter();
            using (var xmlWriter = XmlWriter.Create(stringwriter, new XmlWriterSettings { Indent = true }))
            {
                xmlWriter.WriteStartDocument();
                xmlWriter.WriteStartElement("Root");
                var groups = checkFile.AsEnumerable().GroupBy(x => new { DocNum = x.Field<int>("orderid"), Type = x.Field<string>("Type"), Status = x.Field<string>("Status"), productno = x.Field<string>("productno"), ProductDescription = x.Field<string>("ProductDescription"), uom = x.Field<string>("uom"), customer = x.Field<string>("customer"), remark = x.Field<string>("remark"), U_JobNumber = x.Field<string>("U_JobNumber"), U_SalesPerson = x.Field<string>("U_SalesPerson"), U_JobType = x.Field<string>("U_JobType"), PlannedQty = x.Field<decimal>("PlannedQty"), OriginNum = x.Field<int?>("OriginNum"), orderdate = x.Field<DateTime>("orderdate"), duedate = x.Field<DateTime>("duedate") });
                foreach (var group in groups)
                {
                    xmlWriter.WriteStartElement("productionorder");
                    xmlWriter.WriteAttributeString("orderid", group.Key.DocNum.ToString());
                    xmlWriter.WriteElementString("type", group.Key.Type);    
                        xmlWriter.WriteElementString("status", group.Key.Status);             
                        xmlWriter.WriteElementString("productno", group.Key.productno);                              xmlWriter.WriteElementString("ProductDescription", group.Key.ProductDescription);                       
                      xmlWriter.WriteElementString("PlannedQty",group.Key.PlannedQty.ToString());                                              
                        xmlWriter.WriteElementString("uom", group.Key.uom);
                        xmlWriter.WriteElementString("salesorder", group.Key.OriginNum.ToString());                                                          xmlWriter.WriteElementString("customer", group.Key.customer);                        
                        xmlWriter.WriteElementString("Remarks", group.Key.remark);

                        xmlWriter.WriteEndElement();
                        xmlWriter.WriteElementString("jobdescription", group.Key.U_JobNumber);                 
                        xmlWriter.WriteElementString("salesperson", group.Key.U_SalesPerson);
                    xmlWriter.WriteElementString("jobtype", group.Key.U_JobType);
                    foreach (DataRow row in group)
                    {
                        xmlWriter.WriteStartElement("Components");
                        xmlWriter.WriteElementString("itemno", row.Field<string>("itemno"));
                        xmlWriter.WriteEndElement();
                    }
                    xmlWriter.WriteEndElement();
                    var sql2 = "update IS_XML_generated='Y' from OWOR where DocNum=group.Key.DocNum";
                    clsDB.Execute(sql2);
                }
                xmlWriter.WriteEndElement();
            }
            var xml = stringwriter.ToString();
            XmlDocument docSave = new XmlDocument();
            docSave.LoadXml(stringwriter.ToString());
            docSave.Save(System.IO.Path.Combine(@"C:\DEMO PSL\DOXMLFILE", "Filename.xml"));

System.Data.DataTable checkFile=new System.Data.DataTable（）；
sql=“sql”；
DBCon clsDB=新的DBCon（SAPCompanySettings.MSSQLConnectionString）；
执行（sql，ref checkFile）；
var stringwriter=新的stringwriter（）；
使用（var xmlWriter=xmlWriter.Create（stringwriter，新的XmlWriterSettings{Indent=true}））
{
xmlWriter.WriteStartDocument（）；
writeStarteElement（“根”）；
var groups=checkFile.AsEnumerable（）.GroupBy（x=>new{DocNum=x.Field（“orderid”）、Type=x.Field（“Type”）、Status=x.Field（“Status”）、productno=x.Field（“productno”）、ProductDescription=x.Field（“ProductDescription”）、uom=x.Field（“customer”）、remark=x.Field（“备注”）、U\U JobNumber=x.Field（“U\U JobNumber”），U_SalesPerson=x.Field（“U_SalesPerson”）、U_JobType=x.Field（“U_JobType”）、PlannedQty=x.Field（“PlannedQty”）、OriginNum=x.Field（“OriginNum”）、orderdate=x.Field（“orderdate”）、duedate=x.Field（“duedate”）}；
foreach（组中的var组）
{
writeStart元素（“productionorder”）；
WriteAttributeString（“orderid”，group.Key.DocNum.ToString（））；
WriteElementString（“type”，group.Key.type）；
WriteElementString（“status”，group.Key.status）；
xmlWriter.WriteElementString（“productno”，group.Key.productno）；xmlWriter.WriteElementString（“ProductDescription”，group.Key.ProductDescription）；
WriteElementString（“PlannedQty”，group.Key.PlannedQty.ToString（））；
WriteElementString（“uom”，group.Key.uom）；

WriteElementString（“作业描述”，group.Key.U_作业编号）；
WriteElementString（“salesperson”，group.Key.U_saleperson）；
WriteElementString（“jobtype”，group.Key.U_jobtype）；

{
writeStart元素（“组件”）；
WriteElementString（“itemno”，row.Field（“itemno”）；
xmlWriter.WriteEndElement（）；
}
xmlWriter.WriteEndElement（）；
var sql2=“更新是从OWOR生成的，其中DocNum=group.Key.DocNum”；
clsDB.Execute（sql2）；
}
xmlWriter.WriteEndElement（）；
}
var xml=stringwriter.ToString（）；
XmlDocument docSave=新的XmlDocument（）；
加载XML（stringwriter.ToString（））；
保存（System.IO.Path.Combine（@“C:\DEMO PSL\DOXMLFILE”，“Filename.xml”）；

电流输出：-

xml:-两个顺序保存在同一个文件中

<?xml version="1.0" encoding="utf-16"?>
<Root>
  <productionorder orderid="1">
  ...................
  </productionorder>
  <productionorder orderid="2">
    ...............
  </productionorder>
</Root>

...................
...............

但预期输出：-我需要保存不同的文件 1.xml：-

..............

2.xml：-

<?xml version="1.0" encoding="utf-16"?>
<Root>
  <productionorder orderid="2">
    ............
  </productionorder>
</Root>

............

我交换了using循环和foreach循环。我还修改了文件名，使每个文件名都是唯一的
