如何快速将其转换为C＃类通过LINQ使用访问数据？ 我一定要手动编写的类的任何XML文件呢？ 怎么样的 JSON 格式？

How to quick convert it to C# classes to use access data by LINQ? Do I have to write the class manually for any XML file case? What about JSON format?

时的XSD唯一的解决办法？

Is the XSD the only solution?

推荐答案

您有两种可能性。

假设你有你的XML文件中的这个位置 C：\路径\到\ XML \ file.xml

---

Suppose that you have your XML file in this location C:\path\to\xml\file.xml

1. 开启开发命令提示符
   你可以找到它在开始菜单＆gt;程序＆gt;微软的Visual Studio 2012＆GT; Visual Studio工具 或者，如果您有Windows 8可以开始在输入开发命令提示符 开始屏幕的
2. 键入 CD / DC：\路径\为\ XML更改位置，您的XML文件的目录
3. 创建 XSD文件从XML文件通过键入 XSD file.xml
4. 创建 C＃类键入 XSD / C file.xsd

1. Open Developer Command Prompt
   You can find it in Start Menu > Programs > Microsoft Visual Studio 2012 > Visual Studio Tools Or if you have Windows 8 can just start typing Developer Command Prompt in Start screen
2. Change location to your XML file directory by typing cd /D "C:\path\to\xml"
3. Create XSD file from your xml file by typing xsd file.xml
4. Create C# classes by typing xsd /c file.xsd

这就是它！您已经生成的XML文件中的C＃类 C：\路径\到\ XML \ file.cs

And that's it! You have generated C# classes from xml file in C:\path\to\xml\file.cs

所需的Visual Studio 2012 +

---

Required Visual Studio 2012+

1. 在复制内容的XML文件到剪贴板
2. 添加到您的解决方案新的，空的类文件（移 + <大骨节病>替代 + <大骨节病> C ）
3. 打开该文件，并在菜单中点击编辑＆gt;选择性粘贴＆GT;粘贴XML作为类
   

1. Copy content of your XML file to clipboard
2. Add to your solution new, empty class file (Shift+Alt+C)
3. Open that file and in menu click Edit > Paste special > Paste XML As Classes
   

这就是它！

用法与此辅助类很简单：

Usage is very simple with this helper class:

using System;
using System.IO;
using System.Web.Script.Serialization; // Add reference: System.Web.Extensions
using System.Xml;
using System.Xml.Serialization;

namespace Helpers
{
    internal static class ParseHelpers
    {
        private static JavaScriptSerializer json;
        private static JavaScriptSerializer JSON { get { return json ?? (json = new JavaScriptSerializer()); } }

        public static Stream ToStream(this string @this)
        {
            var stream = new MemoryStream();
            var writer = new StreamWriter(stream);
            writer.Write(@this);
            writer.Flush();
            stream.Position = 0;
            return stream;
        }


        public static T ParseXML<T>(this string @this) where T : class
        {
            var reader = XmlReader.Create(@this.Trim().ToStream(), new XmlReaderSettings() { ConformanceLevel = ConformanceLevel.Document });
            return new XmlSerializer(typeof(T)).Deserialize(reader) as T;
        }

        public static T ParseJSON<T>(this string @this) where T : class
        {
            return JSON.Deserialize<T>(@this.Trim());
        }
    }
}

所有你现在要做的，就是：

All you have to do now, is:

    public class JSONRoot
    {
        public catalog catalog { get; set; }
    }
    // ...

    string xml = File.ReadAllText(@"C:\path\to\xml\file.xml");
    var catalog1 = xml.ParseXML<catalog>();

    string json = File.ReadAllText(@"C:\path\to\json\file.json");
    var catalog2 = json.ParseJSON<JSONRoot>();
