您好,我正在学习C#,并且我正在尝试从user1.xml中显示XML信息,以在ComboBox中选择同一形式的文本框中。
我已经使用此代码设法用名称标签填充了ComboBox。(以便可以选择用户名)
private void Form1_Load(object sender, EventArgs e)
{
XmlDocument sFor = new XmlDocument();
sFor.Load(Path.GetFullPath("User1.xml"));
XmlNodeList SearchList = sFor.SelectNodes("employee/user/name");
foreach (XmlNode Search in SearchList)
{
comboBox1.Items.Add(Search.InnerText);
}
}
XML的格式是
<employee>
<user>
<name>John Smith</name>
<department>PAI</department>
<manager>MD</manager>
<hours>full-time</hours>
<leave>940</leave>
</user>
</employee>
在Combobox中选择后,我将如何(使用Linq或XMLReader或其他方式使用),在TextBox2?
中显示信息谢谢。
我在datagridview寻找"城市"时做了类似的事情。输入字段是TextBox1.Text。我希望这不是过分的。荣誉归功于Stack的海报,向我展示了如何做到这一点!我首先提取特定数据,然后将其加载到列表中。最后,将列表列出了DGV的数据源。这可能适用于组合盒...是吗?
<TaxTbl>
<TaxSite>
<Location>Axx</Location>
<Address>xxx</Address>
<City>aaa</City>
<State> st</State>
<Zip>xxx</Zip>
</TaxSite>
<TaxSite>
<Location>Bxxx</Location>
<Address>xxx</Address>
<City>xxx</City>
<State> st</State>
<Zip>xxx</Zip>
</TaxSite>
</TaxTbl>
var xdoc = XDocument.Load("C:\Users\Harley\desktop\outfile.xml");
var NewDoc = new XDocument(new XElement("TaxTbl",
from anEntry in xdoc.Element("TaxTbl").Elements("TaxSite")
where anEntry.Element("City").Value.Contains(textBox1.Text)
select anEntry));
var MyList =
(from bEntry in NewDoc.Descendants("TaxSite")
select new
{
Location = bEntry.Element("Location").Value,
Address = bEntry.Element("Address").Value,
City = bEntry.Element("City").Value,
State = bEntry.Element("State").Value,
Zip = bEntry.Element("Zip").Value
}).ToList();
cityDGV.DataSource = MyList.ToList();
如果这可以帮助您
XDocument doc = XDocument.Load(Path.GetFullPath("User1.xml"));
var rows = doc.Descendants("employee").Descendants("user").Select(el => new()
{
department = el.Element("department").Value,
manager = el.Element("manager").Value,
hours = el.Element("hours").Value,
leave = el.Element("leave").Value,
});
或像这样的数据集
DataSet ds = new DataSet();
ds.ReadXmlSchema(new StreamReader("User1.xml"));
ds.ReadXml(new StreamReader("User1.xml"));
