Reflection in C#: What It Is, Why It Exists

Short summary

A tutorial explaining C# reflection using a dynamic email template engine as the running example. It contrasts the manual approach of writing separate merge methods per email type against a generic reflection-based solution that inspects object properties at runtime. The article demonstrates how reflection eliminates duplication, scales to new types automatically, and prevents silent placeholder bugs.

• •Reflection allows runtime inspection of types, methods, and properties in .NET
• •Generic template engine replaces N manual merge methods with one reflection-based approach
• •Adding new fields becomes a one-line change with no merge code to update
