将Xpath从java转换为c＃

问题描述

嘿伙计们，我需要你的帮助。

1.我不确定这段代码是什么

2.我怎么重写这个是c＃，因为c＃库中不存在XpathApi。

hey guys pls I need your help.
1. I am not really sure what this piece of code does
2. how do I rewrite this is c#, since XpathApi does not exist in the c# library.

Node objRecorNode;
Node objCurrentField = null;


public boolean setToFirstRecord() {
  try {
       objCurrentField = XPathAPI.selectSingleNode(objRecordNode,"./FIELD");
       if(objCurrentField==null)
       return false;
    else
       return true;
      } catch(Exception e) {
      System.out.println("Error in setToFirstRecord of RecordObject "  + e.getMessage());
       return false;
    }

}

感谢您的帮助，非常感谢

thanks for the help, very greatful

推荐答案

XmlNode objRecordNode;
XmlNode objCurrentField;

public bool SetToFirstRecord()
{
   try {
      objCurrentField = objRecordNode.SelectSingleNode("./FIELD");
      return (objCurrentField != null);
   }
   catch (Exception ex) {
      Debug.WriteLine(string.Format("Error in setToFirstRecord of RecordObject {0}", e.Message()));
      return false;
   }
}

（粗略因为我不经常使用XML文档;但我希望你有这个想法）



[/ EDIT]

(rough because I do not use XML documents so often ; but I hope you got the idea)
