Hi All,

谢谢。



我尝试过：



System.Xml.XmlNodeList章节= doc.SelectNodes（ICD10CM.tabular / chapter）;





System.Xml.XmlNodeList Sections = doc.SelectNodes（ICD10CM.tabular / chapter / sectionIndex）;



foreach（章节中的System.Xml.XmlNode CC）

{

string [] sections = new string [5];

sections [0] = CC.SelectSingleNode（sectionRef）。InnerText;

}

Thanks.

What I have tried:

System.Xml.XmlNodeList Chapters = doc.SelectNodes("ICD10CM.tabular/chapter");


System.Xml.XmlNodeList Sections = doc.SelectNodes("ICD10CM.tabular/chapter/sectionIndex");

foreach (System.Xml.XmlNode CC in Sections)
{
string[] sections = new string[5];
sections[0] = CC.SelectSingleNode("sectionRef").InnerText;
}

推荐答案

移动定义循环外的部分，并使用索引来访问它。或者更好的是，使用列表< string> ，这样您就不必使用固定数量的元素：

Move the definition of sections outside the loop, and use an index to access it. Or better, use a List<string> so you don't have to work with a fixed number of elements:

System.Xml.XmlNodeList Chapters = doc.SelectNodes("ICD10CM.tabular/chapter");
System.Xml.XmlNodeList Sections = doc.SelectNodes("ICD10CM.tabular/chapter/sectionIndex");
List<string> sections = new List<string>();
foreach (System.Xml.XmlNode CC in Sections)
    {
    sections.Add(CC.SelectSingleNode("sectionRef").InnerText);
    }
