I have to make many combination of field and property. I cannot use the implicit property version "{ get; set; }" since the fields need some attributes.
So, in Visual Studio Express 2013, is there a way to have a shortcut to create a property associated with a field I just ended up writing?
Let's say I write;
private MyType myData;
and I press CTRL+P (whatever the shortcut), and it adds
public MyType MyData
{
get { return myData; }
set { myData = value; }
}
just after.
Is it possible?
EDIT:
The Express version however does only have two refactoring functionalities: rename and extract method, the other functionalities like encapsulate are not present.
I guess I'm stuck.
By what you are asking 3 simple clicks will do it like this:
rigth-click in your field then Refactor-->EncapsulateField
And your done.

this might also be useful (Create your own snippets) :

here you have all the code snippets you need including "prop", which is the one you need now!
Hope it helps
Type prop
then press tab
then enter the property name
then press ctrl+.
then click on convert to full property
You should use code snippet and assign hotkey for it.

You know how you can have a property that automatically generates a backing field? Like if I go:
public String SomeProperty {get; set;}
I know that if I want to add code to that property I have to create the backing field as so:
public string someProperty = string.Empty;
public string SomeProperty
{
get { return someProperty; }
set
{
someProperty = value;
DoSomething();
}
}
Basically, what I want to know is... is there any way to do this but without having to create the backing field? For example I could use it to trigger some kind of event that occurs when a property is set. I'm looking for something like this:
public string SomeProperty
{
get;
set { this.OnSomeEvent; }
}
But I know that'll cause a compile error because get needs do declare a body if set does.
I've researched and I cant find anything, but I thought I'd check to see if anyone knew.
I guess what I'm really after is some way to trigger an event when a property is changed but without having to add all that extra clutter. Any suggestions?
Simple answer is no, you can't have it both ways. From .NET Docs:
In C# 3.0 and later, auto-implemented properties make property-declaration more concise when no additional logic is required in the property accessors.
There are not any solutions for this built into the framework, and you cannot modify existing types via reflection (in order to add the logic at runtime). The only way to accomplish this seems to be at compile time.
There is a product http://www.postsharp.net/ that can accomplish this (intercept property/method calls), and there does appear to be a free edition.
The field keyword might be added to C#, see https://github.com/dotnet/csharplang/issues/140, which removes "when no additional logic" requirement for auto properties.
It didn't make it into C# 10 nor 11, but latest comment from compiler team says C# version 12 might have it. They release yearly, so that would be Nov 2023.
When I write code and need new property, i simply write propery name as it would exist already and choose action from menu:
Problem is, that it generates code like this:
protected int SomeNewProperty
{
get { throw new System.NotImplementedException(); }
set { throw new System.NotImplementedException(); }
}
So I need to go there and manually adjust that (actually I prefer to choose Create field from menu and change it to auto property). Anyway, I thought, may be there is a way to change default behavior of "Create property", that it would create auto property instantly?
Update
In Resharper 8 auto properties are available and may be set by default!
You cannot do this in R# (at least in v6). That is, create a pseudo property and have resharper generate the Auto Property stub.
You can still use the superior method that Visual Studio uses. Type out your new property which will show as a syntax error and then CTRL + . shows VS mini menu. Then just hit enter and straight away, the job is done.
It does not take you to the class file which can be distracting too. To use the shortcut above, you don't even need to have you cursor on the broken property name.
So this is better than the method described by Rickard as it is faster and less distracting you away from the code you are writing.
Just when you click Create property it will halt on the type. Hit tab and you will get a context menu with the option to use Auto property.
There is an option to change default body style.
However, the close you can get is
protected int SomeProperty
{
get { return 0; }
set { }
}
There is a default snippet that comes with Visual Studio called 'prop' Just type that, hit , give a type name and give it a name. Done and done.
I know that doesn't answer your question in terms of Resharper, but it is functionality already provided by the Visual Studio IDE.
Greetings all,
I am calling Type.GetProperties(), but after running Dotfuscator, it is returning zero items, when it returned more than zero before.
public class Test
{
public int Number { get; set; }
public void ShowInfo()
{
Type type = this.GetType();
PropertyInfo[] props = type.GetProperties();
Console.WriteLine("type [" + type.Name + "] props count: " + props.Length);
}
}
If I exclude the "Number" property from renaming within Dotfuscator, then it works, but otherwise it doesn't. However, it is not possible for me to do this for all properties in my project, as it would lead to possible bugs.
Are there any workarounds for this method? Or even other "free" obfuscation applications I could use?
I have already tried looking on their website to submit a bug, but I am only using the community edition so there doesn't seem to be as much support for it.
Dotfuscator automatically strips properties (which are just metadata anyway - the real work is done by the get/set pair of methods that are automatically created) during renaming. It also renames the underlying get/set methods as well. Depending on what you are trying to do, you'll need to exclude either the property metadata itself, or the get/set methods (or possibly both) from renaming.
If you need to keep the property metadata intact (for example, to simply list the properties in a Type), you can instruct Dotfuscator to exclude properties from renaming by checking them in the tree view on the Renaming Exclusions tab or using a custom regex property rule. This will only exclude the property metadata - the get/set methods will still be renamed.
If you need to keep the get/set methods (because, for example, you are trying to get or set a property's value by reflection), you can instruct Dotfuscator to exclude those methods from renaming by expanding the property in the tree view and checking the get/set methods underneath, or by using a custom regex method rule.
As the process of obfuscation is not limited to renaming your class members, you can't be sure of that. That's the problem with obfuscation: You basically can't make any assumptions about your class anymore regarding the result of reflection. The only way I can think of is to not use reflection but expressions.
Have a look at this question and its answer to know, what I mean with "expressions": How to raise PropertyChanged event without using string name
By "generate", I mean auto-generation of the code necessary for a particular selected (set of) variable(s).
But any more explicit explication or comment on good practice is welcome.
Rather than using Ctrl + K, X you can also just type prop and then hit Tab twice.
Visual Studio also has a feature that will generate a Property from a private variable.
If you right-click on a variable, in the context menu that pops up, click on the "Refactor" item, and then choose Encapsulate Field.... This will create a getter/setter property for a variable.
I'm not too big a fan of this technique as it is a little bit awkward to use if you have to create a lot of getters/setters, and it puts the property directly below the private field, which bugs me, because I usually have all of my private fields grouped together, and this Visual Studio feature breaks my class' formatting.
I use Visual Studio 2013 Professional.
Place your cursor at the line of an instance variable.
Press combine keys Ctrl + R, Ctrl + E, or click the right mouse button. Choose context menu Refactor → Encapsulate Field..., and then press OK.
In Preview Reference Changes - Encapsulate Field dialog, press button Apply.
This is result:
You also place the cursor for choosing a property. Use menu Edit → Refactor → Encapsulate Field...
Other information:
Since C# 3.0 (November 19th 2007), we can use auto-implemented properties (this is merely syntactic sugar).
And
private int productID;
public int ProductID
{
get { return productID; }
set { productID = value; }
}
becomes
public int ProductID { get; set; }
By generate, do you mean auto-generate? If that's not what you mean:
Visual Studio 2008 has the easiest implementation for this:
public PropertyType PropertyName { get; set; }
In the background this creates an implied instance variable to which your property is stored and retrieved.
However if you want to put in more logic in your Properties, you will have to have an instance variable for it:
private PropertyType _property;
public PropertyType PropertyName
{
get
{
//logic here
return _property;
}
set
{
//logic here
_property = value;
}
}
Previous versions of Visual Studio always used this longhand method as well.
You can also use "propfull" and hit TAB twice.
The variable and property with get and set will be generated.
In visual studio 2019, select your properties like this:
Then press Ctrl+r
Then press Ctrl+e
A dialog will appear showing you the preview of the changes that are going to happen to your code. If everything looks good (which it mostly will), press OK.
If you are using Visual Studio 2005 and up, you can create a setter/getter real fast using the insert snippet command.
Right click on your code, click on Insert Snippet (Ctrl+K,X), and then choose "prop" from the list.
If you're using ReSharper, go into the ReSharper menu → Code → Generate...
(Or hit Alt + Ins inside the surrounding class), and you'll get all the options for generating getters and/or setters you can think of :-)
I created my own snippet that only adds {get; set;}. I made it just because I find prop → Tab to be clunky.

With this, you type your PropType and PropName manually, then type get → Tab, and it will add the get set. It's nothing magical, but since I tend to type my access modifier first anyway, I may as well finish out the name and type.
In Visual Studio Community Edition 2015 you can select all the fields you want and then press Ctrl + . to automatically generate the properties.
You have to choose if you want to use the property instead of the field or not.
Use the propfull keyword.
It will generate a property and a variable.
Type keyword propfull in the editor, followed by two TABs. It will generate code like:
private data_type var_name;
public data_type var_name1{ get;set;}

In addition to the 'prop' snippet and auto-properties, there is a refactor option to let you select an existing field and expose it via a property (right click on the field → Refactor → Encapsulate Field...).
Also, if you don't like the 'prop' implementation, you can create your own snippets. Additionally, a third-party refactoring tool like ReSharper will give you even more features and make it easier to create more advanced snippets. I'd recommend ReSharper if you can afford it.

I don't have Visual Studio installed on my machine anymore (and I'm using Linux), but I do remember that there was an wizard hidden somewhere inside one of the menus that gave access to a class builder.
With this wizard, you could define all your classes' details, including methods and attributes. If I remember well, there was an option through which you could ask Visual Studio to create the setters and getters automatically for you.
I know it's quite vague, but check it out and you might find it.
On behalf of the Visual Studio tool, we can easily generate C# properties using an online tool called C# property generator.
First get Extension just press (Ctrl + Shift + X) and install getter setter ....
After this, just select your variable and right click. Go to Command palette...
And type getter ... It will suggest generate get and set methods. Click on this...
I personaly use CTRL+. and then select-
"Encapsulated Fildes".
That's a short for this option- (How can we generate getters and setters in Visual Studio?).
I marked the short for auto choosing refactoring (CTRL+. )
You just simply press Alt + Ins in Android Studio.
After declaring variables, you will get the getters and setters in the generated code.
