误差：＆QUOT;要插入的节点是从一个不同的文档上下文＆QUOT; [英] Error: "The node to be inserted is from a different document context"

问题描述

当我打电话 XmlNode.AppendChild（），我得到这个错误：

When I am calling XmlNode.AppendChild(), I get this error:

要插入的节点是从一个不同的文档上下文

The node to be inserted is from a different document context.

这code是由这是这个（请忽略可选参数，我在C＃版本为他们过载）的VB 6.0版本转换

This code was converted from its VB 6.0 version which was this (please ignore the optional parameters, I have overloads for them in C# version):

Public Function XMLNewChildNode(ByVal oParent As IXMLDOMNode, ByVal _
    sName As String, Optional ByVal sNamespaceURI As String = "", _
    Optional ByVal sNodeType As String = "element") As IXMLDOMNode
'**************** DESCRIPTION *******************
  'Create a new Child Node for passed Parent.
'***************** VARIABLES ********************
  Dim oNode As IXMLDOMNode
'************************************************
  Set oNode = moDoc.createNode(sNodeType, sName, sNamespaceURI)
  Call oParent.appendChild(oNode)
  Set XMLNewChildNode = oNode
End Function

为什么VB code的工作，而C＃不？是否有VB和C＃如何处理XML之间的差异，我需要知道的？

Why does the VB code work while the C# does not? Are there differences between how VB and C# handle XML, that I need to be aware of?

推荐答案

您需要将节点导入到文档中追加前：

You need to import the node into the document before appending it:

XmlNode oNode = moDoc.CreateNode(sNodeType, sName, sNamespaceURI);

//necessary for crossing XmlDocument contexts
XmlNode importNode = oParent.OwnerDocument.ImportNode(oNode, true);

oParent.AppendChild(importNode);
return oNode;
