How to show method parameter tooltip in C#?

Question

VS2010:

In VB I can place the cursor inside an existing method's parameter brackets and type a 'space', which will bring up the tooltip with description of the parameter I'm at. This is not the case in C#. I have to delete the whole brackets including the parameters, and retype the left bracket, for this tooltip to show. Is there some shortcut or setting to change this behavior? I tried hitting ctrl, shift, alt, but it has no effect.

Ctrl+Shift+Space will do what you want.

You might want to check out a poster of key bindings.

AFAIK, this doesn't bring up parameter info where the caret is within the parentheses for the parameters. – spender Jan 31 '11 at 10:21

Looking at the chart, CTRL+Shift+Space looks like the one. – spender Jan 31 '11 at 10:23
Cool, I even printed it off myself :P – Lloyd Jan 31 '11 at 10:24

Thanks! That works. So then I assume it can not be changed to "automatic" behavior? Btw, here is similar link for VS2010: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=92ced922-d505-457a-8c9c-84036160639f&displaylang=en – bretddog Jan 31 '11 at 10:33

Also make sure you don't have Resharper installed, as it overrides this shortcut. If you do, you can remove the override in the `Tools > Options > Keyboard` menu: search for commands with "CodeSmart". – Protector one Jan 02 '15 at 11:09

What's this called? I would like to remap it. It seems to be `Edit.ParameterInfo` – Jan 22 '15 at 23:32
I wanted the same thing for VS2015, in 2012 it would pop up after the first bracket, in my install of 2015 it didn't, but the ctrl+shift+space worked. Thanks – Chris Feb 05 '16 at 13:24

by default, Ctrl+Shift+Space corresponds to `Edit.ParameterInfo`. – aderesh Dec 10 '20 at 07:23

It's Ctrl-K Ctrl-I for VS2015. In case people from the future are wondering wandering.

I don't understand what you mean exactly. But I use this coding for method parameters tooltip.

/// <summary>
/// Do work function
/// </summary>
/// <param name="id">This is user's Id.</param>
/// <param name="name">This is user's Name.</param>
/// <param name="surname">This is user's surname. </param>
private void DoWork(int id, string name, string surname)
{ 
    // do stuff
}

I believe he already has the XML documentation. The problem is making the tooltip appear for an existing method call. – Cody Gray - on strike Jan 31 '11 at 10:27

Visual Studio 2019 with VsVim extension

Works both in NORMAL and INSERT modes, for C# and C++ with:

Ctrl+Shift+Space

Just make sure to place the caret right after the first parenthesis:

C#

"Value".Contains(|   <-- caret

C++

glClearColor(|  <-- caret

How do you iterate through the parameters? – AnotherDeveloper Oct 19 '20 at 22:54

Ctrl + K, Ctrl + P

Worked for me where Ctrl + Shift + Space didn't. Perhaps due to Resharper?

Unfortunately in 2022 it does not work. IIRC it worked in 2019 Visual Studio. – sergiol Nov 08 '22 at 17:31

The most reliable way to know it (due to plugins etc) is to look it up in settings.

Open settings window: Tools -> Options
Go to Environment -> Keyboard
(optional) Filter commands via Show commands containing: field (e.g. type in "param" there)
In VS 2017, 2019 and 2022 the name is "Edit.ParameterInfo" (default binding is CTRL + SHIFT + P)
In ReSharper 2021 the name is ReSharper.ReShareper_ParameterInfoShow

Also here is a list of all shortcuts in MS docs, which has command names along with description. I find it easier to search commands there rather then inside in-app settings.
