Add and remove #region blocks

Right in the editor, you can quickly surround the current selection with region. JetBrains Rider will add the #region and #endregion directives and place the caret in the position where you can type the region name.

tip

To select a logical code block, press AltShift0= one or more times; to select the current declaration, press AltShift0].

You can also move regions in different ways using the Move code element feature:

• You can move the #region and #endregion directives up and down so that the region includes the neighbouring elements, or so that the elements are left out of the region. To do so, place the caret at the directive that you want to move, press Ctrl+Shift+Alt, and then use the up and down arrow keys.

• You can move the whole region up and down in the scope. To do so, select the whole region including #region and #endregion directives, press Ctrl+Shift+Alt, and then use the up and down arrow keys.

To remove an existing region, press AltEnter and choose the corresponding context action.

Note that you can also apply this action in a wider scope. For example, you can use it to remove all #region blocks in the entire solution:

Regions that surround types and/or type members appear in the Structure window window. You can expand/collapse regions to show/hide items inside them.
