C# Developers : Default Parameters Lambda Expressions

Lambda expressions in C# support default parameters, which allow you to specify default values for some or all of the parameters within a lambda expression. These default parameters offer flexibility when invoking lambda expressions, as they permit you to omit certain arguments during the invocation while relying on the provided defaults. When a lambda expression with default parameters is invoked and specific arguments are not supplied, the default values are used as a fallback.

Default parameters in lambda expressions are especially useful when you want to create more versatile and adaptable lambda expressions that can accommodate various use cases. By specifying default values for parameters within the lambda, you can simplify the invocation process and reduce the need for extensive parameter lists, making your code more concise and readable.

Additionally, it's worth noting that method groups with default parameters and params array parameters can also be assigned to lambda expressions. In such cases, the lambda expression inherits the default parameters and the ability to work with variable-length argument lists, enhancing its versatility and applicability in different programming scenarios. This feature allows developers to create lambda expressions that behave similarly to traditional methods, while still benefiting from the concise syntax and functional programming capabilities of lambda expressions.
