Visual Studio C# statement collapsing

Question

When editing really long code blocks (which should definitely be refactored anyway, but that\'s beyond the scope of this question), I often long for the ability to collapse

Answer 1

Starting with Visual Studio 2017, statement collapsing is built-in.

There are several extensions that perform this task for pre-2017 versions of VS, starting with VS 2010 version:

• C# outline
• C# outline 2012 (@MSDN)
• C# outline 2013 (@MSDN)
• C# outline 2015 (@MSDN)
• Visual Basic and C# Outliner

The last extension supports only VS 2015 and VS 2017, but it's the most powerful one.
It supports syntax coloring inside collapsed blocks, it is more fault-tolerant and optimized.

If the extension doesn't seem to install after you used a browser to download it, try using the built-in Visual Studio extension manager.

Answer 2

In Visual Studio 2019, if you want to collapse braces in catch & finally, collapse switch, case, default, collapse multiple lines of comments, etc.

Try to use C# outline 2019

Answer 3

# region ,#endregion is the smart option.

Answer 4

You can collapse specific blocks of text within visual studio, but you have to turn off automatic outlining.

Right click in your code window and select (Outlining | Stop Outlining)

Then, select some text, right click and select (Outlining | Hide Selection)

When you turn on automatic outlining again, your custom "Regions" will no longer collapse.

Answer 5

Visual Studio 2008 supports regions inside of functions as long as you keep them in the same code hierarchical level

#region Won't work
for(int i = 0; i<Count; i++)
{
//do something
#endregion
}

for(int i=0; i<Count; i++)
{
#region Works fine
//do lots of stuff
#endregion
}

Answer 6

Let me say something different: press(ctrl+m,ctrl+h) or in edit>outlining>hide selection its so useful.
