Switch enum auto-fill - c#

I was typing a switch with an enum in VS 2013 and all case statements filled out automatically after I finished the switch. Now I can't repeat it. I was not hallucinating, the switch filled out with all enum options, one per case, automatically. Looked through MS docs for VS 2013 and didn't find it.
I use quite a few enums and this feature will save me a ton of time if I can find what it is I did to trigger it. Can anyone help?

Notice: This answer applies to performing the switch/enum autogeneration while also using Resharper.
Using Visual Studio 2013 and Resharper 8.2, the previously mentioned methods do not work. Here's how to actually get this generation to work when using Resharper. Hopefully it will save someone the fifteen minutes I just spent figuring this out.
Performing "sw(tab)(tab)" will only generate the following:
switch (nameOfEnumVariable)
{
}
Resharper can generate the labels using Alt + Enter (if your cursor stands in the switch statement) and selecting Generate switch labels as in the following screenshot:
The result looks like this:

Type "sw", and then press tab,tab.

The selected answer is mostly correct, you don't need Resharper as other's have suggested (at least not with Visual Studio Professional 2012+).
1) type "sw" then "[tab][tab]" (as Marvin Smit said)
Which (as jmblack said) will generate something like:
switch (switch_on)
{
default:
}
but then
2) you need to select which thing to enumerate on (switch_on will be highlighted still at this point). So type in the Enum (or your variable of the enum type) while switch_on is highlited and hit [Enter][Enter].
(I just confirmed this worked on my machine running VS2012, and i'm fairly certain this is the same thing i have done on my other machine running VS2013, and i haven't tested other versions of VS (ultimate/express/etc.))

Visual studio 2017, 2019 - without Resharper:
1) write "switch"
2) press two times TAB, then you will see:
switch (switch_on)
{
default:
}
(the switch_on is highlited)
3) retype switch_on to your enum variable or type
4) press ENTER or click somewhere else (pressing TAB does not work), now you should see all the enum items filled:
switch (YOUR_ENUM_VARIABLE_OR_TYPE)
{
case YOUR_ENUM_TYPE.Item1:
break;
case YOUR_ENUM_TYPE.Item2:
break;
case YOUR_ENUM_TYPE.Item3:
break;
default:
break;
}

I think what you need is this:
sw(tab)(tab)enumVariableName(tab)(downArrow)
I tested it and works ( in VS2013 at least).

By default, Visual Studion's snippet works correct. You should type "sw" and then press double "Tab".
If you use Resharper, the snippet doesn't work, because Resharper's snippet has more priority, by default. So, you should turn off resharper's snippet.
Go to "Resharper" -> "Template Explorer"-> "C#" then uncheck "switch". Try "sw" + double "Tab"

I've written a free and open source extension, based on Roslyn, for Visual Studio 2015 and 2017, that not only allows to fill the switch case for an enum, but is also capable of adding new cases if enum values (fields) have been added to the enum type definition, or sort the list of cases by value or name.
It's available here: Enum Case Generator
This is how to use it:

VS 2019 + resharper create an empty switch with your variable. Click on first curly bracket "{" Then press alt + enter You will see Generate switch labels. Screenshot below:

Hi I just ran into the same problem, I just found out that when you do:
switch(nameofvariable){
default:
break;
}
when you are filling the variable and you double click on the variable of your choice (the enum) it will give you all the cases

Can I make Resharper align case clauses in switch statements on one line?

(Note: This, 7-year-old reply refers to a JetBrains request for this feature which was subsequently marked as "done" in 2017. But they've rearranged their Options dialog since then and I cannot find the equivalent. So I am posting again)
I'm typing a switch statement in C#. When the case statements are short, I generally want to line them up in columns because it makes the code easier to grasp at a glance. So for example, I might want it look like this
switch (XyLengthUnit)
{
case LengthUnit.CM: _precision = 6; break;
case LengthUnit.MM: _precision = 3; break;
}
And mostly it works. But every time I get to the end of a line and type the semicolon, Resharper insists on moving the break down to the next line
switch (XyLengthUnit)
{
case LengthUnit.CM: _precision = 6; break;
case LengthUnit.MM: _precision = 3;
break;
}
So I have to hit backspace to fix it. Every time.
I am sure that it is Resharper doing this because when I disable it, the behavior stops and my 'break' statement remains on the same line.
I've gone through every single setting under Resharpers Options >> Code Editing >> C# >> Formatting Style >> Tabs, Indents, Alignment Nothing there seems to change this. I found a few settings under "Line Breaks and Wrapping that seemed appropriate (and related the previously mentioned feature request) but they did not change the behavior
(This is how I have the settings now but I've monkeyed with them extensively. They do not seem to change anything. As soon as I hit semicolon, the break gets moved)
I know that many Resharper settings have "hard breaks" at a certain column and all that but I generally set those to really high numbers (e.g. column 150).
Is there a setting for it that I am missing? Is it possible to make Resharper align things like this?
No, it's not possible right now. The "Place simple case statements" takes effect when there's only one statement inside a case section, where's in your case there are two including the break; statement.

How to customize formatting of code that is generated by "Encapsulate Field"?

Previously I am fairly certain that the "Encapsulate Field" command would turn something like the following:
public int SomeNumber;
into the following (what I want from VS 2015):
private int someNumber;
public int SomeNumber {
get { return someNumber; }
set { someNumber = value; }
}
but in Visual Studio 2015 I am seeing the following:
private int someNumber;
public int SomeNumber {
get {
return someNumber;
}
set {
someNumber = value;
}
}
Is there a way to fix this?
This was a design change in VS2015. In previous versions, the refactoring command paid attention to the Tools > Options > Text Editor > C# > Wrapping > "Leave block on single line" option. With it turned on, you'll get the property getter and setter body the way it encoded in the snippet, braces on the same line. The way you like it.
Different in VS2015, it now pays attention to the Tools > Options > Text Editor > C# > Formatting > New Lines > "Place open brace on new line for methods" setting. You get to choose between "egyptian" braces or having the opening brace separate. Neither of which you like.
Accidents happen when Microsoft creates new VS versions, this was not an accident. Whether this was done by "popular demand" is hard to reverse-engineer, I consider it pretty likely since this refactoring is usually done to write a non-trivial getter or setter, the kind that won't fit a single line. Providing us with a choice between all three possible formatting preferences looks like a problem to me, the existing formatting options are not a good match.
Only real option is to let Microsoft know that you are not happy with the change. There is an existing UserVoice article that proposes a change. You can vote for it or write your own. Post a link to it in your question so other SO users can vote.
Will that help you:

Different Refactoring style for field encapsulation: how to make Visual Studio change it?
This one is corresponding to your question in a certain manner: the question is really related to yours :)
I myself have tried changing the snippet file to suite my file but VS doesn't take effect. What I end up doing is
Encapsulate the fields as usual.
Copy and paste the code into notepad++ and do a Find and Replace.
Find:
(\{)*(\s*)*(get|set)\r\n\s+{\r\n\s+(.*)\r\n\s+\}\s+
Replace with:
$1$3\{$4\}
Paste the result back into VS. VS will format it follow the "Leave block on single line".

Visual Studio 2010 - can't see the value of the variable while in debug

Before I used to point on the variables and they used to show their values. strong textut after I installed Visual Studio 2010 full version, I can't see variables anymore.
Sometimes I would have to do something like that to see te variable:
String var1 = "test";
var1=var1;
Please note, I check variable value after it has been initialized and after the value has been assigned.
The name 'buyCategory' does not exist in the current context
Change to debug compilation and disable compiler optimisation.
Looks like your break point is on the line that inits the variable. YOu need to execute that line ( F10 / Debug->Step Over ) before that variable will come into existence
In the screenshot, buyCategory hasn't yet been initialized or assigned. Press F10 and try again.
It's possible you are in a different thread as the variable you are trying to see in the Locals menu.
Open Solution Explorer -> Right Click on Solution -> Select Properties.
After selecting Properties, you will get one Popup window. In the window change configuration Type to Debug and then click Ok.

What's VS2010 shortcut for surrounding the line in a if block

Let's assume I have a following line
myObject.SomeStatement();
My cursor is at the end of the line.
What's the keboard shortcut to put an if statement around it and obtain:
if ()
{
myObject.SomeStatement();
}
What's the keboard shortcut to put a for loop around it and obtain:
for (int i = 0; i<length; ++i)
{
myObject.SomeStatement();
}
I use Edit.SurroundWith (CTRL+K, CTRL+S) and then select if from the popup list
You can surround with a for in a similar manner.
There are actually many surround templates available - I also use the try and tryf templates quite often (perhaps a sign that I'm doing it wrong ☺).
In addition, please check also this reference page Visual Studio 2010 Keybinding Posters, with details on shortcuts for all VS2010 languages.
As far as i know the behaviour you want isn't quite there, but something close, i think. Take your statement:
myObject.SomeStatement();
and select the line, e.g. by double clicking, and press CTRL+K, CTRL+S, then select the "snippet" you want to apply.

ReSharper formatting: align equal operands

Note to Googlers, this question is somewhat out of date as the requested feature is now supported in the current version of ReSharper 2017.3.1
I like to formatting my code to align right side of equal operands.
Like here:
bool canRead = false;
bool canReadClass = true;
string className = boType.Name;
I've switch to ReSharper recently and found it very useful but cannot find option allowing me format code in described way.
Do you know if there is such option / plugin?
Maybe you know other than ReSharp solution allowing that?
EDIT:
How to decide what part of code shall be aligned?
My convention is aligning all variables in same block.
By "block" I meant part of code not divided by empty lines.
eg
// First block
int count = 10;
string name = "abc";
bool calculate = true;
.....
.....
// Second block
MyOwnType myType = new MyOwntype();
int count = 10;
EDIT -2
I've opened R# ticket for this. If anyone interested please vote!
There is (currently) no way to do this out of the box in ReSharper. Fortunately, ReSharper has a very rich extensibility API (albeit poorly documented). I've spent a lot of time with Reflector trying to figure things out.
We use a similar alignment guideline for class members in a company I work for (to the extreme, we also align method parameters). I wrote a plugin for ReSharper to help me do just that. It's a "Code Cleanup" module, which runs sometime during the code cleanup (Ctrl-E, Ctrl-F) and aligns the code for you. It also makes the class sealed, if possible.
Some examples:
Method parameters:
public void DoSomething(string name,
int age,
IEnumerable coll)
(you will need to change Wrap formal parameters to Chop always in Options->Formatting Style->Line Breaks and Wrapping for this to work properly)
Constants:
private const int RESOURCEDISPLAYTYPE_DOMAIN = 0x00000001;
private const int CONNECT_COMMANDLINE = 0x00000800;
private const int CONNECT_INTERACTIVE = 0x00000008;
private const string RESOURCE_NAME = "Unknown";
You can download the source code from my SkyDrive.
Edit I seem to have lost access to that SkyDrive, and lost the files too. This was before github :(
Please note that you'll need several things to compile/debug it:
Update the Command Line Arguments
in Debug tab in Project
Properties with the correct path of
the output DLL:
/ReSharper.Plugin
"X:\<projects>\MyCompany.CodeFormatter\MyCompany.CodeFormatter\bin\Debug\MyCompany.CodeFormatter.dll"
This allows debugging the plugin via
F5, and it will be
automatically installed in
ReSharper's Plugins in the new
Visual Studio instance which will
open.
The plugin is for ReSharper 4.5 and it references the DLLs of this version. If you installed ReSharper anywhere else except C:\Program Files\JetBrains\ReSharper, you will have to fix the references.
This does not align variables inside methods, but it shouldn't be hard to add :)
After you install this, just run Code Cleanup to fix your alignment (I never got a reply from JetBrains about how to do this during brace/semicolon formatting, unfortunately).
Assembly was renamed to protect the innocent :)
Good luck!
I think it is worth noting that the Visual Studio Productivity Power Tools have an Align Assignments feature.
Here's a link to the Visual Studio 2013 Productivity Power Tools.
You can try this: Code Alignment
It supports
Align by... (Dialog)
Align by position... (Dialog)
Align by Equals
Align by m_
Align by "
Align by .
Align by Space
Productivity Power Tools 2012 also has a command for this: ctrl-alt-]
Other goodies are obviously there as well.
As far as I know, this is unfortunately not possible using Resharper.
Years late, but further to the comment from #MickyD, Resharper can do this for you, see Resharper blog. Go to Resharper/ Options/ Code Editing/ C#/ Tabs, Indents, Alignment. Scroll to the bottom of the options in the right hand window pane to find "Align Similar Code in Columns", click things, enjoy.
