在xml文档对象中添加节点出错

[csxbbb]

System.Xml.XmlElement disAgreeNodeId=oXmlDocument.CreateElement("DisAgreeNodeId");
disAgreeNodeId.Value=node.DisAgreeNodeId.ToString();//此句出错：不能在节点类型上设置值: Element。
请指点

[CinnXu]

node.DisAgreeNodeId.ToString()//这个是什么啊

把代码贴尽可能多一点,能表达清楚一点

[csxbbb]

node.DisAgreeNodeId.ToString()
只是一个字符串值

[orcale]

disAgreeNodeId.Value應該是只讀
using System;
using System.IO;
using System.Xml;

public class Sample
{
public static void Main()
{
Sample test = new Sample();
}

public Sample()
{
try
{
XmlDocument doc = new XmlDocument();
doc.LoadXml("<?xml version=\"1.0\"?>" +
"<!-- Sample XML document -->" +
"<bookstore xmlns:bk=\"urn:samples\">" +
" <book genre=\"novel\" publicationdate=\"1997\" " +
" bk:ISBN=\"1-861001-57-5\">" +
" <title>Pride And Prejudice</title>" +
" <author>" +
" <first-name>Jane</first-name>" +
" <last-name>Austen</last-name>" +
" </author>" +
" <price>24.95</price>" +
" </book>" +
" <book genre=\"novel\" publicationdate=\"1992\" " +
" bk:ISBN=\"1-861002-30-1\">" +
" <title>The Handmaid's Tale</title>" +
" <author>" +
" <first-name>Margaret</first-name>" +
" <last-name>Atwood</last-name>" +
" </author>" +
" <price>29.95</price>" +
" </book>" +
"</bookstore>");

XmlNode currNode = doc.DocumentElement;

//create and add a new element
string prefix=currNode.GetPrefixOfNamespace("urn:samples");
XmlElement newElem=doc.CreateElement(prefix, "style", "urn:samples");
newElem.InnerText="hardcover";

currNode.FirstChild.AppendChild(newElem);

Console.WriteLine("Display the modified XML...");
XmlTextWriter writer = new XmlTextWriter(Console.Out);
writer.Formatting = Formatting.Indented;
doc.WriteTo( writer );
writer.Flush();
writer.Close();

}
catch (Exception e)
{
Console.WriteLine ("Exception: {0}", e.ToString());
}

}
}

System.Xml.XmlElement disAgreeNodeId=oXmlDocument.CreateElement("DisAgreeNodeId");
disAgreeNodeId.Value=node.DisAgreeNodeId.ToString();//此句出错：不能在节点类型上设置值: Element。

---------------------------------------------
要设置为
disAgreeNodeId.InnerText="............"
具体请看
msdn关于 XmlElement类

解决了
