Debugging automatic properties - c#

Is there any way to set breakpoint on setter/getter in auto-implemented property?
int Counter { get; set; }
Other than changing it to standard property (I'm doing it in this way, but to do that I have to change and recompile whole project)

Using Visual Studio 2008, 2010, 2012, 2013:
Go to the Breakpoint window
New -> Break at Function…
For the get, type: ClassName.get_Counter()
For the set, type: ClassName.set_Counter(int)
You'll get a "No Source Available" when the breakpoint is hit, but you'll get the calling location in the call stack.
I found this solution here on MSDN

On Visual Studio 2017:
Hover over "set" word -> right click -> Breakpoint -> Insert Breakpoint
Before:
After:

This question is very old but it is worth noting that it just works in VS 2015.
https://devblogs.microsoft.com/devops/set-breakpoints-on-auto-implemented-properties-with-visual-studio-2015/
class X {
public string name {
set;
get; // setting a breakpoint here will break in VS 2015!
}
}

If I was you, I'd temporarily make the property a standard one backed by an internal field...set your breakpoints, and then you can change it back after.

Set Breakpoints where you are setting property or getting property, No other way.
you can do this by Find All References options
And Since it is only storing values and do not have any code in setter part so what do you debug?

Keybinding for auto-formatting properties in Visual Studio?

Is there a keybinding in VS which allows properties to be formatted between the following two styles?
public string Property
{
get { return "Daniel"; }
}
and
public string Property { get { return "Daniel"; } }
For instance, when autofilling an override Visual Studio will use the top example. I want to be able to highlight the property, hit a keybinding and have it automatically format using the second example.
Alternatively is there any way to configure Visual Studio so it only uses the bottom method? I've tweaked a few settings under Options > C# > Formatting but with no luck.
I realise it's a minor pet peeve, but I'd really like the functionality.
CodeMaid extension for Visual Studio allows you to join required lines of code into a single line.
Just select the code and hit Ctrl+M+J.
You may try your luck here, this should be all keybindings of vs.

Autoproperty debugging

When I use autoproperty for example
public string Prop {get;set;}
compiler generates two functions: get_Prop() and set_Prop(string val). I would like to set breakpoint on one from this function. When I set breakpoint by function this function name debuger never enter in this functions. Intellisense doesn't work in my dialog (Ctrl+B)
My questions:
1) Where compiler save source code with replaced property to function? If it do this.
2) Why Intelisense not working?
3) How to set breakpoint on this functons?
I use VS2013 Ultimate.
1) the compiler don't save source code, it compiles. The implicit backing fields are only present in the IL code.
2) It's a feature, not a bug, I agree it could be great.
3) You have to create a backing field manually in order to put a breakpoint on it.
private string _prop;
public string Prop
{
get { return _prop; }
set { _prop= value; }
}
There is a great solution described here:
Debugging automatic properties
Basically, you can set a breakpoint with Breapooint->Create New and put it on
ClassName.set_PropertyName
or
ClassName.get_PropertyName.
It is also available in Visual Studio 2015, or for earlier versions you can use VS plugins such as Oz Code to do this automatically (break on setter)

Is there a way to instruct visual studio to auto add fields at the bottom of the class instead of the top?

namespace Guilds
{
public class Wizard
{
public void Wear(IClothing clothing)
{
Console.WriteLine("Puts on the {Robe} and {WizardHat}".Fmt(clothing));
}
IClothing _clothes;
IWeapon _weapon; // <== I want my fields added at the bottom of the class!
}
}
I am aware that if you put your fields at the bottom, it will start adding subsequent ones to the bottom of the class as well. I would love to have this as the default behavior even for the first field.
This behavior is usually triggered when pressing Ctrl + . on top of an undeclared field.
Use Regionerate and create your own format template. it's free tool to use with visual studio.
Edit: You can also use CodeMaid because it seems that Regionerate and VS2012 do not work together (I have not tested that combination at all though. I have VS2010)
Edit Adding more to my previous reply. CodeMaid is really cool and you can specify the layout in configuration. Also in configuration, you can specify that file should be formatted on save. This way write your code in anyway you want and have it formatted when you press Ctrl+S! I am one happy user of CodeMaid. Also I am using Visual Studio 2013.

Creating Class Properties in Visual Studio

Using the standard VS IDE, is there a fast way to create class properties that are linked to the local variables?
The class diagram seems to provide something, but it basically just created a property stub. Is there something better / easier out there ?
In VS.NET 2008 you can use refactoring, Encapsulate field (ctrl + r, e).
Here is info about how Refactoring In Visual Studio 2008
If you're talking about just making quick properties, then Auto-Generated properties are 'the bomb'. There's no need for a background local variable unless you plan to do something special in the get or set.
public string SampleProperty { get; set; }
or
public string SampleProperty { get; private set; }
Where you can optionally specify private / protected to limit the property to a setter or getter only. Then, you don't need a local variable and you just use the Property in place of the local variable. The compiler will generate the actual background variable for you.
I think you might be confusing an Auto Generated property with a property stub.
When building classes in Visual Studio (VS), you can generate property setters and getters quickly by defining a field variable, and then right-clicking on the field and selecting Refactor → Encapsulate Field from the popup menu. VS will display a dialog that lets you approve/change the property name, and optionally, preview changes. When you're satisfied, simply click OK. Voilà! VS generates the property!

How can we generate getters and setters in Visual Studio?

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.
<?xml version="1.0" encoding="utf-8"?>
<CodeSnippets
xmlns="http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet">
<CodeSnippet Format="1.0.0">
<Header>
<Title>get set</Title>
<Shortcut>get</Shortcut>
</Header>
<Snippet>
<Code Language="CSharp">
<![CDATA[{get; set;}]]>
</Code>
</Snippet>
</CodeSnippet>
</CodeSnippets>
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;}
Video demonstrating the use of snippet 'propfull' (among other things), at 4 min 11 secs.
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.
