C# 10 introduced file-scoped namespaces, which I would like to use in Visual Studio's class templates. I've updated the 'Class' template file to the following:
namespace $rootnamespace$;
class $safeitemrootname$
{
//I put this comment here to make sure it's using the right file
}
But when I create a new empty class I get this autogenerated code:
namespace ProjectName
{
internal class Class1
{
//I put this comment here to make sure it's using the right file
}
}
What do I need to do to make the auto-generated code for an empty class look like this?
namespace ProjectName;
internal class Class1
{
}
For reference, I am using Visual Studio 2022 Professional and my project is using C#10 with .NET 6.
The location of the class template file that I am modifying is: C:\Program Files\Microsoft Visual Studio\2022\Professional\Common7\IDE\ItemTemplates\CSharp\Code\1033\Class\Class.cs
You have to set up your project's editorconfig to prefer File-scoped namespaces.
Right click your project. Select "Add" → "New Item"
Select "editorConfig File (.NET)"
Double click the new editorconfig file. In the "Code Style" tab set "Namespace declarations" to "File scoped"
The code template will now work as expected.
Check this thread: https://stackoverflow.com/a/69889803
They use a .editorconfig file where you can specify the namespace declaration style. When creating a new file in VS 2022 it will use that new style
I am using VS Community 2017 Version 15.2
When I use the light-bulb suggestions, or manually press (Ctrl + .), it generates a method like this:
using System;
public void f() {
throw new NotImplementedException();
}
I want it to be this way:
public void f() {
throw new System.NotImplementedException();
}
Without the:
using System;
I looked through the settings and also online but could not find the option.
I want this because I like keeping my namespace clean. I don't want to manually delete the using statement every time I use this handy feature.
It is not a common behaviour, and Visual studio does not provide it. If you use Resharper, you can set it manually.
Resharper -> Option
(in option window) Code Editing -> C# -> Code Style
Find Reference qualification and check prefer fully qualified references
I am not able to write "Properties.Settings.Default". It is not coming in the dropdown list. Is there any namespace that we can add?
Add your project namespace to the Properties namespace. The default namespace defined in the project settings.
For instance if your project default namespace is MyApp.
MyApp.Properties.Settings.Default
Make sure you are on the same namespace and try to access the properties like this :
namespace.Properties.Settings.Default
or if you are on different namespace don't forget to use
using namespace
An additional hint on top of the above answers:
Go to solution explorer -> Properties folder -> Settings.settings ->
Settings.Designer.cs file
and see which namespace is being used there. Ensure that you are using this namespace in your code file as others have suggested
Once you setup your environment in the settings under properties of the app. You want to reference it to the project like this:
using App.Properties.Settings
Then in the code you write you can use as example:
userName.Settings.Default
In this case userName is set within the settings.
Set your Setting in your project
go to Project => property => go to setting
Set your element (string,int, ecc...)
Save from program all values
Properties.Settings.Default.User = txtUser.Text; Properties.Settings.Default.Password = txtPass.Text;
Properties.Settings.Default.Save();
if you use Windows 10, this is the directory of setting Values:
C:\Users\AppData\Local<ProjectName.exe_Url_somedata>\1.0.0.0<filename.config>
If I'm not mistaken, since Visual Studio 2015 there's some new feature that grays out redundant parts of namespace usings. Also, when you automatically add an using to some assembly member using quick actions, the grayed part is omitted.
For example, the whole Whatever.Framework.Shared.Data.Mongo would be added as just Shared.Data.Mongo when using quick actions.
Is it possible to completely disable this refactoring feature?
You will see this even going back to Visual Studio 2012 (and possibly older) under the following circumstances:
namespace Test.Foo {
using Test.Foo.Bar; // can write using Bar
public class Class1 {
}
}
vs
using Test.Foo.Bar;
namespace Test.Foo {
public class Class1 {
}
}
The first will grey out the Test.Foo. part in the using statement, as you are inside the namespace declaration. The second will not.
I'm using StyleCop and want to suppress some warning which does not suit my style. I prefer to have solution for
1) in-line code suppressing
2) global setting suppressing
I've searched the internet but still not sure how to do the suppressing.
For method 1), They said to add the lines:
[assembly: SuppressMessage("Microsoft.Design",
"SA1202:All private methods must be placed after all public methods",
Scope = "namespace", Target = "Consus.Client.ClientVaultModule.Services.OnlineDetection")]
But they do not say where and which namespace to be used.
For method 2), they said to use GlobalSuppress file but it seems not easy to search for a how-to do it at the moment.
Please help.
[Edited]
In my case, I have the warning about SA1202: All private methods must be placed after all public methods which is bothering since I group my related codes into regions. I want to suppress those warning for just some certain methods.
Here's what you need:
[SuppressMessage("Microsoft.StyleCop.CSharp.OrderingRules", "SA1202:ElementsMustBeOrderedByAccess")]
An example of inline suppression would be similar to this - examine the namespaces in the code compared to the suppression
namespace Soapi
{
///<summary>
///</summary>
///<param name = "message"></param>
///<param name = "statusCode"></param>
///<param name = "innerException"></param>
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Globalization", "CA1305:SpecifyIFormatProvider", MessageId = "System.String.Format(System.String,System.Object,System.Object)")]
public ApiException(string message, ErrorCode statusCode, Exception innerException)
: base(String.Format("{0}\r\nStatusCode:{1}", message, statusCode), innerException)
{
this.statusCode = statusCode;
}
A global supression file is a file in the root of your project named GlobalSuppressions.cs and might look like this:
// This file is used by Code Analysis to maintain SuppressMessage
// attributes that are applied to this project.
// Project-level suppressions either have no target or are given
// a specific target and scoped to a namespace, type, member, etc.
//
// To add a suppression to this file, right-click the message in the
// Error List, point to "Suppress Message(s)", and click
// "In Project Suppression File".
// You do not need to add suppressions to this file manually.
[assembly: System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Globalization", "CA1305:SpecifyIFormatProvider", MessageId = "System.String.Format(System.String,System.Object,System.Object,System.Object)", Scope = "member", Target = "Soapi.ApiException.#.ctor(System.String,Soapi.ErrorCode,System.String,System.Exception)")]
And you can generate this code automatically by right-clicking on the warning.
Starting with StyleCop 4.3.2, it is possible to suppress the reporting of rule violations by adding suppression attributes within the source code.
Rule Suppressions
http://stylecop.soyuz5.com/Suppressions.html
but it says -
Global Suppressions
StyleCop does not support the notion of global suppressions or
file-level suppressions. Suppressions must be placed on a code
element.
If you've installed StyleCop, you can right-click your project and there will be a StyleCop option. Click this and you'll see you can prevent certain rules from even running against your project. Moreover, you can create a separate rules file to share between different projects. This means you can configure the rules once the way you want them and then share that configuration between all your projects.
For individual overrides, SuppressMessage is the way to go.
Go to Solution Explorer
Go to your project
Expand references
Expand Analyzers
Expand StyleCop.Analyzers
Right click on a particular rule which you want to disable at a global (project) level
Set Rule Set severity -> Select None
Read the admonition from Style Cop, looking for the alphanumeric code. In your case 'SA1202'. Then browse to the corresponding page on the Style Cop website. Change the URL as appropriate https://github.com/DotNetAnalyzers/StyleCopAnalyzers/blob/master/documentation/SA1202.md
Copy the line labelled 'How to Suppress Violations'. Paste the attribute above the class about which Style Cop moans
[SuppressMessage("StyleCop.CSharp.OrderingRules", "SA1202:ElementsMustBeOrderedByAccess", Justification = "Reviewed.")]
Cant you just remove the rule instead of soiling your code?
Same goes for FxCop...
1.
In your case, correct SuppressMessage attribute should like like the following:
[SuppressMessage("StyleCop.CSharp.OrderingRules", "SA1202:ElementsMustBeOrderedByAccess")]
private void SomeMethod()
{
}
Note that you can place it on any other element (e.g, on the class - then all similar violations in the entire class will be supressed).
I also agree that it's quite unobvious what to write in these fields.
Actually, the first one should be the fully qualified name of StyleCop analyser class and could be found from the source code (e.g. from here).
The second one should start with rule code, then colon and the name of the rule enumeration (luckily, it always looks like the rule name displayed in the Settings Editor, but with no whitespaces).
2.
Regarding suppressing rules "globally" - why don't just turn them off via Settings Editor? Settings files are inherited through the file system, so you could easily have one "main" settings file at the "top" of your folder structure, and some other files (holding the "difference" from main) with exceptions made for some projects, if you want so (like described here).
Good luck!
You can disable the rules you don't want in Settings.StyleCop file, which is in the project root folder.
You will need the namespace that contains the rule, which can be found here:
http://stylecop.soyuz5.com/StyleCop%20Rules.html
Settings.stylecop file code for your reference:
<StyleCopSettings Version="105">
<Analyzers>
<Analyzer AnalyzerId="StyleCop.CSharp.LayoutRules">
<Rules>
<Rule Name="ElementsMustBeSeparatedByBlankLine">
<RuleSettings>
<BooleanProperty Name="Enabled">False</BooleanProperty>
</RuleSettings>
</Rule>
</Rules>
<AnalyzerSettings />
</Analyzer>
</Analyzers>
</StyleCopSettings>
Alternatively you could move the code in regions into partial classes. Then the issue with the stylecop rule will go away.
In addition to the helpful answers already in place:
If you suppress a warning in the suppression file GlobalSuppressions.cs,
you can edit that [assembly: SuppressMessage(StyleCop...blabla line and entirely remove the Scope=... and Target=... tags. That makes the suppression global in the project.
The README.md for the StyleCop.Analyzers NuGet package used by Visual Studio 2015+ contains a link to the documentation for the rules. The documentation for each rule contains a "How to suppress violations" section. For the SA1202 rule, the options are:
[SuppressMessage("StyleCop.CSharp.OrderingRules", "SA1202:ElementsMustBeOrderedByAccess", Justification = "Reviewed.")]
and
#pragma warning disable SA1202 // ElementsMustBeOrderedByAccess
#pragma warning restore SA1202 // ElementsMustBeOrderedByAccess
