How to Convert XML Strings to C# Objects?

C# XML String to Object Conversion: A Practical Guide

Receiving XML data via a socket often necessitates converting it into usable C# objects. This process is streamlined using the xsd.exe tool.

Locate xsd.exe: This tool is included with the Windows SDK. Common installation paths include:

• 32-bit systems: C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin
• 64-bit systems: C:\Program Files (x86)\Microsoft SDKs\Windows\v6.0A\bin
• Windows 10 and later: C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\bin (or a later version)

Generating the C# Class:

First, generate an XML Schema Definition (XSD) file from your XML sample:

<code class="language-bash">xsd yourfile.xml</code>

This creates yourfile.xsd. Next, compile this XSD into a C# class:

<code class="language-bash">xsd yourfile.xsd /c</code>

The resulting yourfile.cs file contains a C# class ready for deserialization.

Deserialization using XmlSerializer:

The XmlSerializer class handles the conversion of the XML string into your C# object. Here's how to deserialize from various input sources:

1. From a File:

<code class="language-csharp">XmlSerializer serializer = new XmlSerializer(typeof(msg));
msg resultingMessage = (msg)serializer.Deserialize(new XmlTextReader("yourfile.xml"));</code>

2. From a Memory Stream:

<code class="language-csharp">XmlSerializer serializer = new XmlSerializer(typeof(msg));
MemoryStream memStream = new MemoryStream(Encoding.UTF8.GetBytes(inputString));
msg resultingMessage = (msg)serializer.Deserialize(memStream);</code>

3. From a StringReader:

<code class="language-csharp">XmlSerializer serializer = new XmlSerializer(typeof(msg));
StringReader rdr = new StringReader(inputString);
msg resultingMessage = (msg)serializer.Deserialize(rdr);</code>

Remember to replace "yourfile.xml" and msg with your actual file path and class name, respectively. This approach provides flexibility in handling XML strings received from various sources.
