C#中的XML文件和数据读取 [英] XML file and data reading in C#

问题描述

我有一个3D对象及其数据点.数据由1000点组成.
以下是数据点.

I have a 3D object and their data points. Data consists of 1000 points.
The following are for the data points.

public static List<myline> OpenProject(string _file)
        {
            List<myline> Lines = new List<myline>();
            XmlDocument doc = new XmlDocument();
            doc.LoadXml(_file);
            XmlNodeList coordinates = doc.SelectNodes("/Siene/MyLine/Coordinates");
            foreach (XmlNode coordinat in coordinates)
            {
                int x1 = Int32.Parse(coordinat["Start"].Attributes["X"].Value);
                int y1 = Int32.Parse(coordinat["Start"].Attributes["Y"].Value);
                int z1 = Int32.Parse(coordinat["Start"].Attributes["Z"].Value);
                MyLine czg = new MyLine(x1, y1, z1);
                lines.Add(czg);
            }
            return lines;
        }

而不是从外部文件(doc.LoadXml(_file))加载XML文件必须位于解决方案资源管理器中，并且所有数据点都必须能够从那里读取.
该行"doc.LoadXml(_file);"必须删除.也就是说，从XML文件读取的数据必须不需要"OpenFileDialog"，并且必须在代码内部.

你能告诉我怎么做吗?
问候，
Mark

Instead of loading from an external file (doc.LoadXml(_file), the XML file must be in solution explorer and all data points must be able to read from there.
The line "doc.LoadXml(_file);" must e removed. That is, data reading from XML file must not need "OpenFileDialog" and must be inside the code.

Could you say me how it can be done.

Mark

推荐答案

我建​​议使用LINQ来解析XML，这很整洁.

I recommend using LINQ to parse your XML, it''s much neater.

StreamResourceInfo sri = System.Windows.Application.GetResourceStream(new System.Uri("pack://application:,,,/MediaData/germanDiaIndex.xml"));

XmlTextReader xmlReader = new XmlTextReader(sri.Stream);

是我的应用从资源读取XML文件的方式.如您所见，sri.Stream为您提供了用于读取数据的流，如果将其移动到LINQ，我敢肯定您可以使用流来做到这一点.

is how my app reads an XML file from resources. As you can see, sri.Stream gives you a stream to use to read the data, if you move it to LINQ, I''m sure you can use a stream to do that.

一种解决方案是将XML文件包含在项目资源中.有关如何对Jet DB执行此操作的示例，请参见此链接 [ ^ ]，其中您可以修改以包含所需的任何类型的文件.

One solution is to include the XML file in your project resources. For an example of how to do this for a Jet DB, see this link[^], which you can modify to include any sort of file that you want.
