"You can also change to suggestion mode, in which only the text you type is inserted into the code. For example, if you enter an identifier that is not in the list and press TAB, in completion mode the entry would replace the typed identifier. To toggle between completion mode and suggestion mode, press CTRL+ALT+SPACEBAR or click Edit/IntelliSense/Toggle Completion Mode."
For the current version of Visual Studio Code (2020), you can change to suggestion mode by going to File > Preferences > Settings and then going to Extensions > TypeScript and then checking TypeScript: Disable Automatic Type Acquisition. Or, after going to Settings, you can search for "Type Acquisition" in "Search Settings" and then check TypeScript: Disable Automatic Type Acquisition.
If you use Vs2017 and the setting resets everytime you launch Vs, i created a small script that automatically disables space completion at launch using Visual Commander Extension:

If you're using Resharper and Visual studio 2017, you may need to use a combination of the existing answers to stop getting the autocomplete behaviour when pressing space. This is too long for a comment so added an answer.
Make sure in Visual studio that intellisense Toggle Complete Mode is off/unselected (as noted in other answers). Note: If you turn on the "Text editor" icons in the VS toolbar at the top, you'll see an extra icon that gets highlighted on and off showing you whether intellisense is toggled on or off. AND
In the resharper dropdown on the toolbar (Resharper > Options...), Go to IntelliSense > Completing Charactes > and then uncheck the "Complete on space" box for C#.
Now autocomplete doesn't occur when pressing space (can still use tab, etc to autocomplete).
(Related aside: This autocomplete on space is really bad if you use VSVim, because you can't by default use the typically vim ESC key to 'get out' of the autocomplete mode. e.g. it's very difficult to even type in the static
modifier for a variable/function without it changing to some other autocomplete choice.)
change the setting for Editor: Accept Suggestion On Enter to off
Visual Studio 2019 Pro -> Options -> Text Editor -> Advanced -> disable "Responsive code completion"
This disables Completion Mode, but doesn't take effect when VS is restarted. You have to enable & disable it again after each restart, which is worse than using the Toggle Completion Mode menu option.
Since it is in Options, it is probably supposed to be a permanent setting.
