# Using Properties (C# Programming Guide)

Properties combine aspects of both fields and methods. To the user of an object, a property appears to be a field, accessing the property requires the same syntax. To the implementer of a class, a property is one or two code blocks, representing a [get](../../language-reference/keywords/get.md) accessor and/or a [set](../../language-reference/keywords/set.md) accessor. 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. A property without a `set` accessor is considered read-only. A property without a `get` accessor is considered write-only. A property that has both accessors is read-write. In C# 9 and later, you can use an `init` accessor instead of a `set` accessor to make the property read-only.

Unlike fields, properties aren't classified as variables. Therefore, you can't pass a property as a [ref](../../language-reference/keywords/ref.md) or [out](../../language-reference/keywords/out-parameter-modifier.md) parameter.
