This topic lists all predefined surround templates for C# in JetBrains Rider 2021.2. For more information about surround templates, see Surround code fragments with templates

Template	Details
`()`	Surround the selection with parentheses Scope C# 2.0+, C++ expressions Body ($SELECTION$$END$) Parameters `SELECTION`- The text selected by the user before invoking the template. `END`- The caret position after the template is applied. Before expansion After expansion
`{}`	Surround the selection with braces Scope C# 2.0+, C++ statements Body { $SELECTION$$END$ } Parameters `SELECTION`- The text selected by the user before invoking the template. `END`- The caret position after the template is applied. Before expansion After expansion
`foreach`	foreach block Scope C# 2.0+ statements Body foreach ($TYPE$ $VARIABLE$ in $COLLECTION$) { $SELECTION$$END$ } Parameters `COLLECTION`- Show basic code completion list at the point where the variable is evaluated `TYPE`- Suggest type for a new variable declared in the template `VARIABLE`- When executed in variable declaration (where variable name should stand), suggests name for the variable. `SELECTION`- The text selected by the user before invoking the template. `END`- The caret position after the template is applied.
`for`	Simple "for" loop Scope C# 2.0+ statements Body for (int $INDEX$ = 0; $INDEX$ < $UPPER$; $INDEX$++) { $SELECTION$$END$ } Parameters `INDEX`- Suggests non-used name which can be used for an index variable at the evaluation point. `UPPER`- no macro `SELECTION`- The text selected by the user before invoking the template. `END`- The caret position after the template is applied. Before expansion After expansion
`#if`	Scope C# 2.0+ except strings, at line start Body #if $expression$ $SELECTION$$END$ #endif Parameters `expression`- Evaluates to the specified constant value. `SELECTION`- The text selected by the user before invoking the template. `END`- The caret position after the template is applied.
`#region`	Surround the selection with a region Scope C# 2.0+ except strings, at line start Body #region $name$ $SELECTION$$END$ #endregion Parameters `name`- Evaluates to the specified constant value. `SELECTION`- The text selected by the user before invoking the template. `END`- The caret position after the template is applied. Before expansion After expansion
`namespace`	Add a namespace to the selected code Scope C# 2.0+ types and namespaces Body namespace $name$ { $END$$SELECTION$ } Parameters `name`- Evaluates to the specified constant value. `SELECTION`- The text selected by the user before invoking the template. `END`- The caret position after the template is applied. Before expansion After expansion
`tryf`	try finally Scope C# 2.0+ statements Body try { $SELECTION$ } finally { $END$ } Parameters `SELECTION`- The text selected by the user before invoking the template. `END`- The caret position after the template is applied.
`try`	try catch Scope C# 2.0+ statements Body try { $SELECTION$ } catch ($EXCEPTION$ $EX_NAME$) { $SELSTART$System.Console.WriteLine($EX_NAME$); throw;$SELEND$ } Parameters `EXCEPTION`- Evaluates to the specified constant value. `EX_NAME`- When executed in variable declaration (where variable name should stand), suggests name for the variable. `SELECTION`- The text selected by the user before invoking the template.
`while`	while loop Scope C# 2.0+ statements Body while ($expression$) { $SELECTION$$END$ } Parameters `expression`- Show basic code completion list at the point where the variable is evaluated `SELECTION`- The text selected by the user before invoking the template. `END`- The caret position after the template is applied. Before expansion After expansion
`do`	do...while loop Scope C# 2.0+ statements Body do { $SELECTION$$END$ } while ($expression$); Parameters `expression`- Suggests variables of the specified type. `SELECTION`- The text selected by the user before invoking the template. `END`- The caret position after the template is applied.
`if`	if statement Scope C# 2.0+ statements Body if ($expr$) { $SELECTION$$END$ } Parameters `expr`- Show basic code completion list at the point where the variable is evaluated `SELECTION`- The text selected by the user before invoking the template. `END`- The caret position after the template is applied. Before expansion After expansion
`lock`	lock statement Scope C# 2.0+ statements Body lock ($expression$) { $SELECTION$$END$ } Parameters `expression`- Suggests variables of the specified type. `SELECTION`- The text selected by the user before invoking the template. `END`- The caret position after the template is applied. Before expansion After expansion
`using`	using statement Scope C# 2.0+ statements Body using($resource$) { $SELECTION$$END$ } Parameters `resource`- Show basic code completion list at the point where the variable is evaluated `SELECTION`- The text selected by the user before invoking the template. `END`- The caret position after the template is applied. Before expansion After expansion
`cast`	Cast the selection to a specific type Scope C# 2.0+ expressions Body (($TYPE$)$SELECTION$) Parameters `TYPE`- Guess type expected at this point `SELECTION`- The text selected by the user before invoking the template. Before expansion After expansion
