我如何使用条件迭代 if 语句 if (i < current Subject nodes inside xml file) 然后显示每个数据

Question

这是我当前的代码，它在 1 个单输入文本框中输出模块。

XElement root = XElement.Load("Data.xml");
            var subjects = from subject in root.Descendants()
                          where subject.Name.LocalName.Contains("Subject")
                          select new
                          {
                              subname = subject.Element("subjectName").Value,
                              subid = subject.Element("subjectId").Value,
                              subvalue = subject.Element("subjectvalue").Value
                          };

            foreach (var subject in subjects)
            {
                Console.WriteLine(subject); 
                //you can use subject like this:
                string subName = subject.subname;
                string subID = subject.subid;
                string subValue = subject.subvalue;
                TextBox[] info = new TextBox[6];



                textBox1.AppendText("Subject Name :  " + subName + "  Subject Id :  " + subID + "  Subject Value :  " + subValue + " " );
            }

我如何更改此代码，以便根据 xml 文件中当前存在的标签数量动态创建输入文本框。

这是我试过的一些代码：

 foreach (var subject in subjects)
            {
                Console.WriteLine(module);
                subname = subject.Element("subjectName").Value,
                subid = subject.Element("subjectId").Value,
                subvalue = subject.Element("subjectvalue").Value

            for (int i = 0; i < 2; i++)
            {
                info[i] = new TextBox();
                info[i].Location = new System.Drawing.Point(50, 114 + i * 25);
                info[i].Size = new System.Drawing.Size(300, 15);
                info[i].Text = @"";
                this.Controls.Add(info[i]);

                info[i].AppendText("Subject Name :  " + subName + "  Subject 
                Id :  " + subID + "  Subject Value :  " + subValue + " " );
            }
        }

但是此代码在两个动态创建的输入框字段上显示相同的数据。我怎样才能使 if 条件类似于 if (i < current Subject nodes inside xml file) 然后遍历它们，将每个数据显示到动态创建的输入文本框中。

这是我的 xml 文件的样子：

<PersonDetails>
  <Person>Teacher</Person>
  <keystage3>
    <Subject>
      <subjectName>maths</subjectName>
      <subjectId>qq1</subjectId>
      <subjectvalue>20</subjectvalue>
    </Subject>
    <Subject>
      <subjectName>english</subjectName>
      <subjectId>aaa</subjectId>
      <subjectvalue>40</subjectvalue>
    </Subject>
  </keystage3>
  <keystage4>
  </keystage4>
</PersonDetails>

按照上面的解释，试试这个：

    int y = 114;
    foreach (var subject in subjects)
    {
            Console.WriteLine(module);
            subname = subject.Element("subjectName").Value,
            subid = subject.Element("subjectId").Value,
            subvalue = subject.Element("subjectvalue").Value

            TextBox box = new TextBox();
            box.Location = new System.Drawing.Point(50, y);
            box.Size = new System.Drawing.Size(300, 15);
            box.Text = @"Subject Name :  " + subName + "  Subject Id :  " + subID + "  Subject Value :  " + subValue + " ";
            this.Controls.Add(box);
            y += 25;
    }

我如何使用条件迭代 if 语句 if (i < current Subject nodes inside xml file) 然后显示每个数据

How can i iterate through if statement with condition if (i < current Subject nodes inside xml file ) then display data for each
