Declaring Local Variables and Access the Default Values of Types
Explore how to declare local variables in C# using explicit types and the var keyword for type inference. Understand the scope and lifecycle of local variables within methods. Discover techniques for accessing and assigning default values for various data types, including value and reference types, to manage your data effectively during development.
We will learn how to declare local variables inside C# method bodies. We will learn to specify the type explicitly, like string or int, and use the var keyword to let the compiler infer the type based on the value assigned. Additionally, we will explore how to get and set the default values of types.
Local variables
Local variables are declared inside methods, and they only exist during the execution of that method. Once the method returns, the memory allocated to any local variables is released. Strictly speaking, value types are released, while reference types must wait for garbage collection.
Specifying the type of a local variable
Let’s explore local variables declared with specific types and using type inference:
