C# Corner·2yDifferences Between IEnumerable and IQueryable in C#
Understanding the differences between IEnumerable and IQueryable in C# is crucial for optimal data manipulation and querying. IEnumerable is used for in-memory data collections and supports deferred execution, while IQueryable is designed for remote data querying and can be translated into query languages like SQL. Using IEnumerable is best for local data collections, whereas IQueryable is ideal for querying large external data sources efficiently.

Discover some lesser-known features and tricks in .NET that can significantly enhance your development experience. Learn about global using directives, string interpolation enhancements, Span<T>, top-level statements, source generators, file-scoped namespaces, nullable reference types, custom attributes, records, and .NET Interactive Notebooks.
C# Corner·2yDiscard Variable in C# .NET
The discard variable, introduced in C# 7.0 and represented by an underscore (_), is a special, read-only variable used to ignore values intentionally. This feature can lead to more readable and maintainable code by avoiding unnecessary variables. Common usage scenarios include deconstructing tuples, pattern matching, handling out parameters, and optimizing LINQ queries. The discard variable enhances code clarity and can aid in performance optimization by reducing memory usage.
Snyk·2yPreventing SQL injection in C# with Entity Framework
SQL injection (SQLi) is a severe security threat that happens when malicious SQL code is injected into user inputs, potentially compromising the database. To avoid SQLi, it's crucial to avoid using string concatenation for SQL queries. Instead, Entity Framework (EF) offers secure options: LINQ for most queries, FromSqlInterpolated for raw SQL using string interpolation, and FromSqlRaw when explicit parameters are defined. Tools like Snyk Code can help detect unsafe code during development.
