Is { get; set; } useful?

Definitely. One of the use of it is , it reduces amount of code to be written. Let say your class has 10 property then in this case your code will become more lengthy if you dont use auto implemented property.

This type of properties are called as auto implemented property and compiler will generate get and set method for you.

hi,

using this get and set you can protect the values, whether you want to allow read only, write only or both, this property is for security purpose we can use.

Yes. It does a lot. Programmers call these accessors, also known as a property. A class or a struct has properties providing the means to read and write the data “encapsulated” inside a class or struct. Using your example, a name property, the idea is that not just any aspect of an application can just nilly-willy access and use the name field. The application must create an instance of the class and access the property in order to access the name field.

 

The get is used to read the data. Perhaps the application needs to put a name on a customer form, if so it will use the get portion of the property.

 

The set is used to write data. Perhaps the name is being updated because a customer got married and the last name has changed. The data is written to the field via property and later saved to a database on a button click.

 

A property with only get is read only.

A property with only set is write only.

A property with both is read and write.

 

I use these all time when I program. Its very common.

yes,

 

With evolution of C# from 2.0 to 3 or latest versions

 

following

 

public string Name { get; set; }

 

is good.

 

It will create the property.

Thanks.
