Question

这是我的XML文件，我想在文本框中输入ID并将其他数据输入其他文本框。

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

<Users>
<User Name="aa" Occupation="dd" Date_Of_Birth="123456" NIC="123123" 
ID="79461" />
<User Name="Ali Rasheed" Occupation="Student" Date_Of_Birth="111694" NIC="4550246607037" ID="12661" />
  <User Name="Asif Rasheed" Occupation="Civil Engineer" Date_Of_Birth="241190" NIC="4550346603073" ID="90939" />
  <User Name="Sadaf Sohail" Occupation="Teacher" Date_Of_Birth="112233" NIC="445566677999" ID="72508" />
  <User Name="Shahnaz Bano" Occupation="Retired Principle" Date_Of_Birth="223311" NIC="454564974149" ID="65199" />
  <User Name="Alex" Occupation="Programmer" Date_Of_Birth="111694" NIC="45522002211447" ID="44534" />
</Users>

这是我的代码

var data = XElement.Load(@"C:\GenesisSolutionsCRMSBuild12101\XMLDatabase.xml").Descendants("User");
foreach (var textbox in Controls.OfType<TextBox>())
{
    var value = data.FirstOrDefault(v => v.Attribute("ID").Value == textbox.Name.Replace("txt", "").ToLower());
    if (value != null)
    {
        textBox1.Text = value.Attribute("Name").Value;
        textBox2.Text = value.Attribute("Occupation").Value;
        textBox3.Text = value.Attribute("Date_Of_Birth").Value;
        textBox4.Text = value.Attribute("NIC").Value;
    }
}

无需遍历所有控件。它就像从ID文本框中读取Text属性一样简单：

var data = XElement.Load(@"C:\GenesisSolutionsCRMSBuild12101\XMLDatabase.xml")
                   .Descendants("User");

// Get the ID the user entered
string id = idTextBox.Text;

var user = data.FirstOrDefault(v => v.Attribute("ID").Value == id);
if (user != null)
{
    textBox1.Text = user.Attribute("Name").Value;
    textBox2.Text = user.Attribute("Occupation").Value;
    textBox3.Text = user.Attribute("Date_Of_Birth").Value;
    textBox4.Text = user.Attribute("NIC").Value;
}

您可能需要考虑将textBoxN重命名为更有用的内容，例如nameTextBox。
