Question

根据以下代码，我创建了xml文件并迭代地写入它。但问题是它是覆盖文件。我想将新元素追加到文件中，这里foreach迭代地将wrobj的内容写入xml，但是再次覆盖

XmlTextWriter xtWriter = new XmlTextWriter("demoxml.xml",Encoding.UTF8);
xtWriter.Formatting = System.Xml.Formatting.Indented;
xtWriter.WriteStartElement("Selected-Workspace");
xtWriter.WriteStartElement("Context-Details");

xtWriter.WriteStartElement("Conid");
xtWriter.WriteString(it.id);
xtWriter.WriteEndElement();

xtWriter.WriteStartElement("Attributes"); //attributes started

xtWriter.WriteStartElement("name");
xtWriter.WriteString(it.attributes.name);
xtWriter.WriteEndElement();
xtWriter.WriteStartElement("organizationReference");
xtWriter.WriteString(it.attributes.organizationReference);
xtWriter.WriteEndElement();
xtWriter.WriteStartElement("organizationReferenceName");
xtWriter.WriteString(it.attributes.organizationReference_name);
xtWriter.WriteEndElement();
xtWriter.WriteStartElement("type");
xtWriter.WriteString(it.attributes.type);
xtWriter.WriteEndElement();

xtWriter.WriteEndElement();// End Attributes
foreach (WorkspaceRootObject wro in wrObj) 
{
    xtWriter.WriteStartElement("Workspace-Details"); // Workspace start

    xtWriter.WriteStartElement("WorkspaceId");
    xtWriter.WriteString(wro.id);
    xtWriter.WriteEndElement();
    xtWriter.WriteStartElement("name");
    xtWriter.WriteString(wro.name);
    xtWriter.WriteEndElement();
    xtWriter.WriteStartElement("description");
    xtWriter.WriteString(wro.description);
    xtWriter.WriteEndElement();
    xtWriter.WriteStartElement("context-id");
    xtWriter.WriteString(wro.contextId);
    xtWriter.WriteEndElement();

    xtWriter.WriteEndElement(); //End Workspace
}

xtWriter.WriteEndElement();
xtWriter.WriteEndElement();
xtWriter.Flush();
xtWriter.Close();
