I have a xml file named "numbers.xml" like this:
我有一个名为“数字”的xml文件。xml”是这样的:
<?xml version="1.0" encoding="utf-8" ?>
<program>
<box id="aaa" value="78678"/>
<box id="bbb" value="37287"/>
<box id="ccc" value="783"/>
<box id="ddd" value="7867"/>
<box id="eee" value="786"/>
<box id="fff" value="23"/>
<box id="ggg" value="453"/>
<box id="hhh" value="4537"/>
</program>
I want to read this xml file and fill textboxes. But in windows forms application txtAAA.text
value must take id="aaa" value which is 78678. Likewise txtBBB.text
value must take id="bbb" value which is 37287. How can I do this?
我想读取这个xml文件并填充文本框。但是在windows窗体应用程序txtAAA中。文本值必须取id="aaa"值,即78678。同样txtBBB。文本值必须取id=“bbb”值,即37287。我该怎么做呢?
Edit:
编辑:
I tried like this:
我试着像这样:
XmlDocument xmldoc = new XmlDocument();
xmldoc.Load(openfiledialog1.FileName);
XmlNodeList nodelist = xmldoc.DocumentElement.ChildNodes;
XmlNode xmlnode = nodelist.Item(0);
txtAAA.Text = xmlnode.Attributes["id"].InnerText;
But "aaa" is shown in textbox. It was totally failure. –
但是“aaa”显示在文本框中。这是完全的失败。- - - - - -

You could create a list of the xml items and assign the based on the TextBox name in a foreach loop
您可以创建xml项的列表,并根据foreach循环中的文本框名称分配它们
Assuming TextBox names are:
假设文本框的名称是:
txtAAA
txtBBB
txtCCC
...etc
you can just remove the txt
part to find the correct value id
您可以删除txt部分以找到正确的值id
var data = XElement.Load("C:\\Test.xml").Descendants("box");
foreach (var textbox in Controls.OfType<TextBox>())
{
var value = data.FirstOrDefault(v => v.Attribute("id").Value == textbox.Name.Replace("txt","").ToLower());
if (value != null)
{
textbox.Text = value.Attribute("value").Value;
}
}

nMaybe this line of code will help you:
也许这行代码会帮助你:
TextBox textBox = this.Controls.OfType<TextBox>().FirstOrDefault(tb => tb.Name == "idFromXMl");
In your case, where you have more textboxes I would save the result of this.Controls.OfType<TextBox>()
in a collection and the work on with this.
在您的例子中,如果有更多的文本框,我将把this. controls . oftype

You can use XPath to find the node.
可以使用XPath查找节点。
Then find the attribute, 'value'.
然后找到属性“value”。
XmlDocument xmldoc = new XmlDocument();
xmldoc.Load( openfiledialog1.FileName );
XmlNode nodeAAA = xmldoc.SelectSingleNode( "/program/box[@id='aaa']" ); //XPath Query here.
txtAAA.Text = nodeAAA.Attributes["value"].InnerText;
