您好,我需要您的超级帮助。我对 C# 不太熟练,我在这上面堆了大约 6 个小时。所以请如果有人知道帮助我。谢谢
我有这样的 XML
<COREBASE>
<AGENT>
<AGENT_INDEX>1</AGENT_INDEX>
<AGENT_PORTER_INDEX>
</AGENT_PORTER_INDEX>
<AGENT_NAME>John</AGENT_NAME>
<AGENT_SURNAME>Smith</AGENT_SURNAME>
<AGENT_MOBILE_NUMBER>777777777</AGENT_MOBILE_NUMBER>
</AGENT>
<AGENT>
<AGENT_INDEX>2</AGENT_INDEX>
<AGENT_PORTER_INDEX>1
</AGENT_PORTER_INDEX>
<AGENT_NAME>Charles</AGENT_NAME>
<AGENT_SURNAME>Bukowski</AGENT_SURNAME>
<AGENT_MOBILE_NUMBER>99999999</AGENT_MOBILE_NUMBER>
</AGENT>
</COREBASE>
而且我需要在 Windows 窗体组合框中按索引选择代理,然后编辑他的属性并将其保存到 xml。我找到了如何编辑和保存它但我不知道为什么但它保存到第一个代理并覆盖他在 XML 中的属性但不是在选定的.. :-(
如有任何帮助,我会很高兴
private void buttonEditAgent_Click(object sender, EventArgs e)
{
XmlDocument AgentBaseEdit = new XmlDocument();
AgentBaseEdit.Load("AgentBase.xml");
XDocument AgentBase = XDocument.Load("AgentBase.xml");
var all = from a in AgentBase.Descendants("AGENT")
select new
{
agentI = a.Element("AGENT_INDEX").Value,
porterI = a.Element("AGENT_PORTER_INDEX").Value,
agentN = a.Element("AGENT_NAME").Value,
agentS = a.Element("AGENT_SURNAME").Value,
agentM = a.Element("AGENT_MOBILE_NUMBER").Value,
};
foreach (var a in all)
{
if ("" == textBoxEditAgentIndex.Text.ToString())
{
MessageBox.Show("You must fill Agent Index field !!", "WARNING");
}
else
{
// AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_INDEX").InnerText == textBoxEditAgentIndex.Text
if (a.agentI == textBoxEditAgentIndex.Text.ToString())
{
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_INDEX").InnerText = textBoxEditAgentIndex.Text;
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_PORTER_INDEX").InnerText = textBoxEditAgentPorterIndex.Text;
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_NAME").InnerText = textBoxEditAgentName.Text;
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_SURNAME").InnerText = textBoxEditAgentSurname.Text;
AgentBaseEdit.SelectSingleNode("COREBASE/AGENT/AGENT_MOBILE_NUMBER").InnerText = textBoxEditAgentMobile.Text;
AgentBaseEdit.Save("AgentBase.xml");
ClearEditAgentTxtBoxes();
}
}
}
}
我是在正确的道路上,但我没有看到门还是我完全错了?谢谢大家。巫女
好的,我尝试过这种方式,但它没有改变内部文本
string agentIndex = comboBoxEditAgentI.SelectedItem.ToString();
XmlDocument AgentBaseEdit = new XmlDocument();
AgentBaseEdit.Load("AgentBase.xml");
XDocument AgentBase = XDocument.Load("AgentBase.xml");
var xElemAgent = AgentBase.Descendants("AGENT")
.First(a => a.Element("AGENT_INDEX").Value == agentIndex);
xElemAgent.Element("AGENT_MOBILE_NUMBER").Value = textBoxEditAgentMobile.Text;
xElemAgent.Element("AGENT_SURNAME").Value = textBoxEditAgentSurname.Text;
AgentBaseEdit.Save("AgentBase.xml");
