In this code snippet, we will take a look at lambda expressions, Func and Action in C#.Func is simply a more compact way of defining a delegate/function pointer while Action is the exact same thing as Func but for methods that return void. The lambda operator () => is a more compact way to define an anonymous method that can then be assigned to a delegate or passed into another method as a parameter. It’s very often combined with LINQ to form very concise queries that all fit into a single line of code.

In this code snippet, we will take a look at unsafe code, pointers, stack allocation and spans in C#. C# has managed memory unlike for example C/C++. This means that you don’t have to allocate or clear memory by yourself and in the case of .NET the CLR(common language runtime) takes care of memory allocation and garbage collection. This also means that in C# you can’t work with a pointer or allocate your variables on the stack which is common practice in C/C++.

In this code snippet, we will take a look at async and await in C#.

The aysnc keyword enables a method to use the await keyword. These two keywords together enable us to execute code asynchronously. When called an async method will return a Task.

In this code snippet, we will learn how to do some basic queries using LINQ(Language Integrated Query) in C#.LINQ is used to work with data within C# and can be used on enumerable types(IEnumerable or IQueryable interface) like lists, arrays, … A query can be made by using an SQL query like syntax or by method chaining. The latter is often combined with the lambda operator to specify some kind of condition as the parameter to the function/method.
