使用文本編寫器將多個元素添加到XML C＃

Question

我需要以下輸出

<BatchFile>
   <BatchFileHeader>
     <MessageType>MSG103</MessageType>
     <Version>456</Version>
   <BatchFileHeader>

   <Vendor>
     <VendorType>VVV</VendorType>
   </Vendor>
</BatchFile>

以下是我的代碼

StringWriter stringwriter = new StringWriter();
XmlTextWriter xmlTextWriter = new XmlTextWriter(stringwriter);
xmlTextWriter.Formatting = Formatting.Indented;
xmlTextWriter.WriteStartDocument();

xmlTextWriter.WriteStartElement("BatchFileHeader");
xmlTextWriter.WriteElementString("MessageType", "MSG103"); 
xmlTextWriter.WriteElementString("MessageVersion", "456"); 
xmlTextWriter.WriteEndElement();

xmlTextWriter.WriteStartElement("Vendor");
xmlTextWriter.WriteElementString("Vendor", "VVV"); 
xmlTextWriter.WriteEndElement();

但我收到以下錯誤

狀態Epilog中的令牌起始元素將導致無效的xml文檔

我究竟做錯了什么 ？

您忘了寫最外面的StartElement <BatchElement> 。

增加他的關注者應該可以解決您的問題；

StringWriter stringwriter = new StringWriter();
XmlTextWriter xmlTextWriter = new XmlTextWriter(stringwriter);
xmlTextWriter.Formatting = Formatting.Indented;
xmlTextWriter.WriteStartDocument();

xmlTextWriter.WriteStartElement("BatchElement");

xmlTextWriter.WriteStartElement("BatchFileHeader");
xmlTextWriter.WriteElementString("MessageType", "MSG103"); 
xmlTextWriter.WriteElementString("MessageVersion", "456"); 
xmlTextWriter.WriteEndElement();

xmlTextWriter.WriteStartElement("Vendor");
xmlTextWriter.WriteElementString("Vendor", "VVV"); 
xmlTextWriter.WriteEndElement();

xmlTextWriter.WriteEndElement();
xmlTextWriter.WriteEndDocument();
