Microbiology is the study of organisms that are invisible to the naked eye. These organisms include bacteria, viruses (even though they are not technically alive), and some fungi. Microbes are found everywhere and even help produce many of the foods we enjoy through a process called fermentation.
Func and Action Delegates take the C# language to a new functional programming level. Lambda Expressions are tightly entwined in the LINQ infrastructure. We take a brief look at each. Lambda Expressions. A lambda expression is an unnamed method that you write in place of a delegate instance. The compiler immediately converts the lambda expression to either: â¢ A delegate instance. â¢ An expression tree, of type Expression<TDelegate>, representing the code inside the lambda expression in a traversable object model.
C# 3.0 includes built-in generic delegate types Func and Action, so that you don't need to define custom delegates as above. Func is a generic delegate included in the System namespace. It has zero or more input parameters and one out parameter. The last parameter is considered as an out parameter. For example, a Func delegate that takes one input parameter and one out parameter is defined in the System namespace as below: Func in C#: namespace System { public delegate TResult Func< in T, out TResult>(T arg); } The last parameter in the angle brackets > is considered as the return type and remaining parameters are considered as input parameter types as shown in the following figure.
