我正在使用XML
和XMLDocument
读取XmlNodeReader
文件。我不知道while循环会发生什么,它无法运行代码的几个部分。
这是我的C#代码:
public string TitleXml;
public string NameXml;
public string TypeXml;
public string ValueXml;
public Guid GuidXml;
public string DataString;
XmlDocument xdoc = new XmlDocument();
xdoc.LoadXml(MyParent.xmlstring);
XmlNodeReader xreader = new XmlNodeReader(xdoc);
while (xreader.Read())
{
switch (xreader.Name)
{
case"GUID":
GuidXml = Guid.Parse(xreader.ReadInnerXml());
//after this break the name of the xreader changes.
break;
case "Type":
TypeXml = xreader.ReadInnerXml();
break;
case "Name":
NameXml = xreader.ReadInnerXml();
break;
case "Title":
TitleXml = xreader.ReadInnerXml();
break;
}
}
xreader.Close();
}
这是我的XML:
<Item>
<GUID>9A4FA56F-EAA0-49AF-B7F0-8CA09EA39167</GUID>
<Type>button</Type>
<Title>Save</Title>
<Value>submit</Value>
<Name>btnsave</Name>
<MaxLen>5</MaxLen>
</Item>

它并没有完全回答你的问题,但是(至少根据我)解决这个问题的简单方法是:
XDocument doc = XDocument.Load("test.xml");
string TitleXml = doc.Descendants("Title").Single().Value;
string NameXml = doc.Descendants("Name").Single().Value;
string TypeXml = doc.Descendants("Type").Single().Value;
string ValueXml = doc.Descendants("Value").Single().Value;
Guid GuidXml = Guid.Parse(doc.Descendants("GUID").Single().Value);

我也认为你应该使用Linq-to-XML,但是对于你的例子,我会明确列出这些元素,如下所示(可编译的示例程序):
using System;
using System.Xml.Linq;
namespace ConsoleApplication1
{
internal class Program
{
static void Main()
{
string xml =
@"<Item>
<GUID>9A4FA56F-EAA0-49AF-B7F0-8CA09EA39167</GUID>
<Type>button</Type>
<Title>Save</Title>
<Value>submit</Value>
<Name>btnsave</Name>
<MaxLen>5</MaxLen>
</Item>";
XElement elem = XElement.Parse(xml);
Guid GuidXml = Guid.Parse(elem.Element("GUID").Value);
Console.WriteLine(GuidXml);
string TypeXml = elem.Element("Type").Value;
Console.WriteLine(TypeXml);
string NameXml = elem.Element("Name").Value;
Console.WriteLine(NameXml);
string TitleXml = elem.Element("Title").Value;
Console.WriteLine(TitleXml);
}
}
}
