property 's arguments are getx, setx, delx and a doc string. In the code below property is used as a decorator. The object of it is the x function, but in the code above there is no place for an object function in the arguments.
A property should always encapsulate one or more fields, and should never do any heavy lifting or validation. If you need a property such a UserName or Password to have validation, change their type from strings to Value Objects. There is an unspoken contract between a class-creator and the consumer.

Descriptors like property need to be in the type's dictionary to work their magic. So those in a class definition primarily affect the behaviour of instances of the class, with minimal effect on the behaviour of the class itself (since the class is the type of the instances).
First, just to recap: to change the identity property, the DB manager (mysql, sqlserver, etc.) will always ask you to drop and recreate the table because that field is the heart of the table. So you need to trick the EF to do a workaround for you. Add a second Id element to the model class with an obvious name like duplicateId. Copy

There are a number of solutions to this question that work in strict mode, but some are better than others. Solutions that do not appear to iterate through every property are the fastest solutions. Bernie White's solution and esskar's solution (modified) Solutions that look as though they iterate through every property are slower. sebke CCU's solution and dan-gph's solution The solution that ...
Here is the package Sets the value of a property of an object by its path from the root. The object can be a complex object and the property can be multi level deep nested property or it can be a property directly under the root. ObjectWriter will find the property using the property path parameter and update its value.
A property can have a 'get' accessor only, which is done in order to make that property read-only When implementing a get/set pattern, an intermediate variable is used as a container into which a value can be placed and a value extracted.
Example: If an object is Person, with property Id. How can I get all Person and use Distinct on them with the property Id of the object? ... How can I get just Person1 and Person3? Is that possible? If it's not possible with LINQ, what would be the best way to have a list of Person depending on some of its properties?
39 You can get a property by name using the Select-Object cmdlet and specifying the property name (s) that you're interested in. Note that this doesn't simply return the raw value for that property; instead you get something that still behaves like an object.
No, it's not the problem. The property "main" exists. It's not a runtime-problem, but compile-time. And I'm not accessing the property through a variable, but "main" is really the name of the property.
DefaultValueAttribute is intended to be used by the VS designer (or any other consumer) to specify a default value, not an initial value. (Even if in designed object, initial value is the default value). At compile time DefaultValueAttribute will not impact the generated IL and it will not be read to initialize the property to that value (see DefaultValue attribute is not working with my Auto ...
