When you reference the property, except as the target of an assignment, the get accessor is invoked to read the value of the property. If ((value > 0) & (value _name // the Name property

Properties are declared in the class block by specifying the access level of the field, followed by the type of the property, followed by the name of the property, and followed by a code block that declares a get-accessor and/or a set accessor. Properties have many uses: they can validate data before allowing a change they can transparently expose data on a class where that data is actually retrieved from some other source, such as a database they can take an action when data is changed, such as raising an event, or changing the value of other fields. Therefore, you cannot pass a property as a ref or out parameter. Unlike fields, properties are not classified as variables. In C# 9 and later, you can use an init accessor instead of a set accessor to make the property read-only. A property that has both accessors is read-write.
A property without a get accessor is considered write-only.
A property without a set accessor is considered read-only. The code block for the get accessor is executed when the property is read the code block for the set accessor is executed when the property is assigned a new value. To the implementer of a class, a property is one or two code blocks, representing a get accessor and/or a set accessor. To the user of an object, a property appears to be a field, accessing the property requires the same syntax. Properties combine aspects of both fields and methods.
