I have a C# project and I am mapping a lot of classes from Json models.
Some of the names are colliding so I have to setup namespaces every time. I generate the classes with an online tool to create C# classes from JSON, so by default the classes don't have a namespace.
Is there any way, with right click on the class or some tool on Visual Studio 2019, that allows me to automaticaly select a bunch of classes and set a namespace for them? Or right click a class and set it's namespace as it's path in the filesystem from the workspace folder?
The problem is that right now, my only chocie is copying the namespace, pasting it on every class and surrounding the code with brackets again and again. I just want to make this proces easier.
Also I know it's not needed to place every single class in a namespace, but to prevent execution time errors and keep the code sorted, I prefer to do so.
You can Paste JSON As Classes in Visual Studio.
It will create the classes with the current namespace. Simply create a new class, "Paste JSON As Classes" and it will create every model from the JSON on the clipboard.
You can user Resharper to adjust namespaces of existing classes.

# Francesc Bosch.
For changing the namespace of an existing class, you can right click on your current namespace and select Rename -> change to your new namespace-> click Apply.
If you have multiple depths of the namespace, Visual Studio will not allow you to type dots. However, if you copy and paste a dot, it will succeed despite the warning.
You could also move the class to the changed target namespace.
1.Right-click the name of the class you want to move -> select Quick Actions and Refactorings... -> click Move to namespace...
2.In the dialog box that opens, select the target namespace you'd like to move the type to.

I get this strange thing when I create a new class, Next to the namespace name I get a .Classes which all I can tell prevents me from creating an instance of the class and hides it.
I would include the screen shot but im not sure how I do this. Please help so you can better understand the question.
Thanks
The namespace within Visual Studio will depend on two things:
The default namespace defined within the project properties.
The folder structure within your project.
I think that within your project you have a folder Classes where you put (well as the name guesses) your classes. Due to this fact Visual Studio will automatically append this name to the default namespace.
So either manually change the namespace manually right after you added a new class or move the file one level up within your folder structure of the project.
So I have this solution in visual studio 2013. Currently the solution tree looks like this:
MySolution
>MyProjectA
>MyProjectB
>MyProjectC
The default is that each class in the project folder has the namespace same as the project folder name.
But I would like that each class in each project folder have a namespace that starts with the solution name. For example if there is a class named MyClass in MyProjectA I want it's namespace to be MySolution.MyProjectA
Is there a way to automatically to this in Visual Studio? I could go and change all the namespaces my self...but I rather would love to see if its possible to do this automatiaclly.
In each project's settings, there is a Default Namespace that is used whenever you add new files to a project. The default value is the project name, but you can customize it. You can change that and then any new files added will use the desired namespace.
For any existing files, a Find and Replace can provide a relatively quick cleanup (find: namespace MyProjectA -> replace with: namespace MySolution.MyProjectA, only search within current project).
Download ReSharper, it has a lot of such features. Install it, after that you just have to rename each project as MySolution.ProjectA,B,C and then right click on the project and select option refactor and then click adjust namespaces. This will do the trick, only thing I see here is that you will need to rename your projects.
Does anybody know how one can change the namespace of a "Coded UI Test Map" also known as UIMap?
Or how the designer does the naming?
When adding a UIMap to your project, you get to cs-files:
e.g.
UIMap.cs
UIMap.Designer.cs
The designer file is auto generated (thus not for editing yourself) and the other file is for own customizations.
In my case I want to change the namespace of both files because I added some folders to organise stuff.
What I did was manually changing the namespace of both files. But since the designer generates file 2) the namespace was also changed again, screwing up my references.
Now I hoped to find a property to enter my own namespace naming. The property I found was for the file "UIMap.uitest", named "Custom Tool Namespace". This property didn't do the trick.
I also had a look in the xml of "UIMap.uitest" to find a namespace reference but again no success.
So I guess the naming is hardcoded by the designer...
The designer always generates this namespace:
namespace TestProject.UIMaps.UIMapClasses
"TestProject" is the default sln namespace
"UIMaps" is my added folder
"UIMapClass": don't no the origin but seem to be auto-generated from the name of the "Coded UI Test Map" (here UIMap) + "Classes".
Can anybody confirm the namespace naming convention by the designer? Or knows a way to manually fix it?
If you are talking about the root namespace, it's in the project properties dialog
right click the project
select the properties menu item
on the application tab, look for the Default namespace: text box and put what you want in there. It can consist of several levels
e.g.
BigNamespace.CompanyNamespace.ITProject.Solution.Project..... etc.
when you perform any action that will require a rewrite of the file, those namespace lines get rewritten. Or you can do it by hand.
I looked it up because it was giving me heartburn too.
First, a little background.
Currently namespaces and assemblies in our codebase (~60 assemblies, thousands of classes) looks like
WidgetCompany.Department.Something
We have now been spun off such that we are selling the software that drives a WidgetCompany, so we 'd like to rename the namespaces & assemblies
NewCompany.Something
Under normal circumstances I'd probably just stick with the old namespace, but the problem is our customers don't want to see the name of one of their competitors anywhere in the application. In the off chance that they see a stack trace, assembly properties etc, it shouldn't show up. It's not meant to hide our associates or do anything sinister, we just need to make sure that people know we are a separate entity, separate management, and they don't need to worry about data being shared etc.
Now the question. What is the best way to perform this type of all encompassing rename?
The following would need to change:
Namespace for (almost) every class in
the application
Every using statement in the application which references the old names
Folder structure for each project
References between projects which rely on changed folder structure
.Sln files which reference the changed folder structure
Any references to
those classes which are fully
qualified (should be few and far
between)
Any references to those
classes in xml config files (config
sections etc)
AssemblyInfo.cs files for every assembly
AssemblyName in every .csproj file
Am I stuck with the find-replace-pray strategy or is there something better?
Right click on your current namespace and select Refactor -> Rename and change the name in the pop up that comes up after a while. Enter your new name and click ok.
If you have multiple depths to your namespace, then Visual Studio won't let you type a dot. However, if you copy and paste a dot, despite a warning, it will do the business.
To completely change to the new name, you will likely need to make additional changes manually. You can find where by performing a project search (ctrl+shift+f) for other references to the name in the Project, Solution, or other supporting files from a separate text editor like VS Code. Finally, folders may need to be changed manually as well.
ReSharper. Get version 5.1 from JetBrains for free for 30 days (more than enough time to do your renaming). Put the cursor on the namespace you want to change and hit Ctrl-R twice (ReSharper Rename). It'll work with a namespace any number of levels deep, and converts any usage of that namespace to the new one. However, you will have to change every unique namespace in your solution (unless you just go with Find/Replace)
Visual Studio 2019 Community Edition supports this as described here. It works for any hierarchy (with dots, root namespace changes etc) and correctly updates all dependencies.
Place your cursor in the class name
Press Ctrl+. to trigger the Quick Actions and Refactorings menu
Select Move to namespace
In the dialog box that opens, select the target namespace you'd like to move the type to
If you have ReSharper:
Right click project, Properties. Change Default namespace to desired
namespace.
Right click project, Refactor -> Adjust Namespace to update all
the namespaces to use the default namespace
Then just let it do its magic.
Firstly I would try Refactor->Rename option. But as mentioned in comment for another answers it doesn't work that good (Or I haven't found how to make it working). So I prefer using following scenario, especially if you want to add some addiotional namespace.
1) Rename your root namespace (WidgetCompany) to something like NAMESPACE_TO_BE_REPLACED using Refactor-Rename
2) Replace NAMESPACE_TO_BE_REPLACED with your final namespace (NewCompany.WidgetSoftware) using find-n-replace dialog
And do not forget to rename projects, default namespaces, etc.
Open a random class in [WidgetCompany.Department.Something]
Edit->Find and Replace->Replace in Files
Type "WidgetCompany.Department.Something" in FindWhat area
Type "NewCompany.Something" in Replace with area
Select Current Project in Look in area.
Replace All
Alternative solution if you've already partially renamed:
Open find and replace (shortcut ctrl + h)
Make sure regex is selected (icon like .*)
Paste the full name of your current namespace, for example YourSolution.YourProject
Paste this regex YourSolution.Your[partiallyRenamedNamespaceCharacters].*
Make sure Entire Solution is selected not Current Document
Run
For Visual Studio 2022 this has finally been solved:
Right-click on the project or solution (not the directory or file)
Select "Sync Namespaces"
The namespaces in your entire project should now reflect the folder structure.
I'm doing some architectural cleanup that involves moving a bunch of classes into different projects and/or namespaces. Currently I'm moving the files by hand, building, and then manually adding using Foo statements as needed to resolve compilation errors. Anyone know of a smarter way of doing this? (We're a CodeRush and Refactor! shop, but I'd be interested to hear if Resharper has support for this)
Visual Studio 2019 provides at least 2 built-in options:
'Move to namespace...' refactoring can be triggered on any class, and VS will prompt for the target namespace.
'Change namespace to...' refactoring is provided for when the current file namespace doesn't match with the folder structure.
This can be used to move individual classes to a different namespace by:
creating the desired folder structure
moving the file
applying the mentioned refactoring (CTRL+. with the cursor over the namespace)
These operation ensures that all references are updated accordingly.
Visual Studio 2010 has the possibility to rename a namespace. Place the cursor over the namespace name and press F2. Or simply rename it in the code and press Shift+Alt+F10, Enter after seeing the red squiggle appear.
Reharper can also rename namespaces. Quote:
The Rename Namespace refactoring
allows users to rename a specific
namespace and automatically correct
all references to the namespace in the
code. The following usages are
renamed:
Namespace statements
Using directives
Qualified names of types
As mentioned in the comments, this answer is now outdated. Please see the up-to-date answer below
Resharper is the only tool I am aware of what has this ability. There is also a lot of other functionality that it has that is missing in CodeRush and Refactor!
This answer applies to at least Visual Studio 2013 and 2015 with no resharper required
Move class files to new folder
Open 'Find and replace'
Select 'Replace in Files'
Type the original namespace definition in the 'Find what' field eg. MyCorp.AppStuff.Api
Type the new namespace definition in the 'Replace with' field eg. MyCorp.AppStuff.Api.Extensions
Select the new folder using the 'Look in' field's browse button ..., or type the folder path
Press the Replace All button
There are partial solutions for VS 2015 & VS 2017 without Resharper using free extensions.
One extension which I like today (end of 2017) is the Fix Namespace VS Extension:
https://marketplace.visualstudio.com/items?itemName=vs-publisher-599079.FixNamespace#overview
It analyses the folder structure of your solution and offers namespace refactoring using that. Unfortunately it isn't perfect: It doesn't track dependencies that well, but solved the lion's share of the work for me.
With Resharper: CTRL+R+O
Then press the down arrow key twice to select Move Type To Another Namespace.
Since the answer above was provided (I'm guessing) this feature has been added to CodeRush. Just place the carat on the Type to be moved and you'll see a Move Type to Namespace option on the Refactor! context menu. This will move the type to the new namespace and update references. You may still want to move the file to a solution folder that matches the name of the namespace though.
It's not the best outcome but can be done without plugins or tools, only with Visual Studio. Find and replace in Entire Solution, Match case, Match whole word.
Find what: class name, Replace with: New.Namespace.ClassName (fully qualified class name).
If you have 100+ references of the moved class and other classes in old namespace what are not moved this is the only foolproof and free solution I found. The only case when it leads to errors is when you have same class name in other namespace.
If you cannot, or do not want to use Re$harper, Notepad++ is your friend:
Make sure you don't have usaved changes inside Visual Studio for the files you need to move to the new namespace
Open all the files that contain the namespace that needs to be changed in Notepad++
Open Find & Replace (CTRL + H)
Fill the Find what and Replace with fields
Press Replace All in All Opened Documents
Save all changes in all documents (CTRL + SHIFT + S)
Switch to Visual Studio and reload all the documents (Yes to all at the prompt)
DONE
