XML to C# Converter

About XML to C# Converter

The XML to C# Converter parses any well-formed XML document and generates corresponding C# classes complete with XML serialization attributes. It is ideal for developers who need to deserialize XML feeds, SOAP responses, or configuration files into strongly-typed .NET objects. Instead of manually mapping every element and attribute, this tool reads the XML structure and produces ready-to-use classes in seconds.

How It Works

The converter walks the XML DOM tree, inspecting each element's children, attributes, and text content. It infers .NET types from the values it encounters — numbers become int or decimal, date strings become DateTime, and true/false literals become bool. Repeated sibling elements are automatically detected and mapped to List<T> collections. The result is a complete class hierarchy decorated with [XmlRoot], [XmlElement], and [XmlAttribute] annotations that work out of the box with System.Xml.Serialization.XmlSerializer.

Key Features

• Automatic type inference — detects string, int, decimal, bool, and DateTime values from XML element content for accurate property typing.
• XML attribute support — generates [XmlAttribute] properties for XML attributes alongside element properties, preserving the full document model.
• Nested element handling — creates child classes for complex nested XML structures, maintaining a clean one-class-per-element approach.
• Collection detection — recognizes repeated sibling elements and maps them to List<T> properties for easy iteration.
• PascalCase naming — converts hyphenated or camelCase XML element names into idiomatic C# PascalCase property names.
• Namespace preservation — handles XML namespaces and generates appropriate [XmlNamespace] decorations.
• CDATA handling — preserves CDATA content as string properties without data loss.

Step-by-Step Guide

1. Load XML — paste your XML into the input editor, upload an .xml file, or fetch XML from a URL.
2. Set options — configure the root class name, toggle PascalCase naming, and enable nullable types if needed.
3. Convert — click Convert to C# or press Ctrl+Enter to generate the classes.
4. Review — inspect the output in the syntax-highlighted right panel to verify property types and attribute decorations.
5. Export — copy the C# code to your clipboard or download it as a .cs file for your project.

Use Cases & Scenarios

• Converting SOAP API response samples into C# DTOs for WCF, HttpClient, or RestSharp consumers.
• Generating models from RSS or Atom feed XML for content aggregation and syndication applications.
• Creating typed configuration classes from legacy XML settings files in .NET Framework or .NET Core projects.
• Scaffolding data models from XML export files for database import and ETL workflows.
• Building strongly-typed wrappers for XML-based file formats like SVG, XHTML, or industry-standard schemas.

Best Practices

Provide a representative XML sample that includes all possible elements and attributes. If your XML has optional elements that appear only in some responses, combine multiple samples into a single document so the converter captures every field. Enable nullable types for elements that might be absent in real data. After generating the classes, run them through your project's XML deserialization pipeline to verify round-trip fidelity before committing to your codebase.

Did You Know?

XML remains one of the most widely used data interchange formats in enterprise systems, financial services (FIX, FIXML), healthcare (HL7, FHIR XML), and government data feeds. Having accurate C# models for these schemas accelerates integration and reduces the risk of data mapping errors in production systems.
