如何使用for循环编写XML文件？

Question

我正在尝试创建一个非常简单的XML文件的快速程序.我想创建一个XML文件,该文件使用'for循环'多次创建XML的一部分.当我构建时,我得到一个错误,说"无效的表达式术语"为'.我检查我的括号平衡,它似乎确实检查出来.

有谁知道这个错误意味着什么？

    static void Main(string[] args)
    { 
        XDocument myDoc = new XDocument(
        new XDeclaration("1.0" ,"utf-8","yes"),
        new XElement("Start"),

        for(int i = 0; i <= 5; i++)
        {
                         new XElement("Entry", 
                             new XAttribute("Address", "0123"),
                             new XAttribute("default", "0"),

                        new XElement("Descripion", "here is the description"),

                        new XElement("Data", "Data goes here ")

                );

            }
        );

        }

您目前正在尝试for在语句中使用循环.那不行.

选项:

• 使用Enumerable.Range创建一个范围值,然后变换使用Select:

  XDocument myDoc = new XDocument(
      new XDeclaration("1.0" ,"utf-8","yes"),
      // Note that the extra elements are *within* the Start element
      new XElement("Start",
          Enumerable.Range(0, 6)
                    .Select(i => 
                         new XElement("Entry", 
                             new XAttribute("Address", "0123"),
                             new XAttribute("default", "0"),
                             new XElement("Descripion", "here is the description"),
                             new XElement("Data", "Data goes here ")))
  );
  

• 首先创建文档,然后在循环中添加元素

  XDocument myDoc = new XDocument(
      new XDeclaration("1.0" ,"utf-8","yes"),
      new XElement("Start"));
  for (int i = 0; i <= 5; i++) 
  {
      myDoc.Root.Add(new XElement("Entry",
                         new XAttribute("Address", "0123"),
                         new XAttribute("default", "0"),
                         new XElement("Descripion", "here is the description"),
                         new XElement("Data", "Data goes here "));
  }
