Properties Usage - C# Coding Standard 12
As we know C# is a object oriented language. Properties support encapsulation which is one of the pillar of object oriented concepts. Today we discuss properties usage coding standards in C#.
• Name the properties using noun or noun phrase
• Instead of public or protected variables, always use properties
• If property returning arrays or collection, property name should be ended with Collection
• If the method is logical data member then use property instead of method
• Always use automatic properties instead of normal properties if get and set method doesn't contain any logic
• Name the Boolean properties like IsConnected or IsValid
• Read-only properties can set via only constructor and we can not change these values in any other places other than in constructor. So use read-only properties where user can not change the value
• Never use write-only properties, instead use method
• We need to set default value for all properties
• If a property
returns an Enum then property name should be same as Enum name • All properties which
need to set, set the values in constructors • If the set method of
property throwing an exception, we need preserve the previous state of that
property
• Don't throw the exception from get method of the property
• Your properties should allow to set values in any order. Object should not depend on the order of the properties while setting the values
• While assigning the value to property, always validates the value in set method only not in any other places
