Advanced C# 🚀Performance Optimization Techniques With Example

In the fast-paced world of software development, performance is not just a nice-to-have — it’s often a critical requirement. As applications scale and user expectations for speed grow, developers must continually refine their skills to write efficient, high-performing code.

For C# developers, this means diving deep into the advanced features of the language and the .NET runtime to squeeze out every ounce of performance.

Here’s a list of top advanced C# performance optimization techniques, along with examples to illustrate each concept.

1. Use Span<T> for Memory-Efficient Operations

Span<T> enables you to work with slices of memory without allocations, reducing GC pressure. It’s ideal for performance-critical scenarios like parsing or working with large datasets.

Example:

2. Avoid Boxing and Unboxing

Boxing and unboxing cause unnecessary memory allocations and degrade performance. Prefer generics to avoid them.
