.NET (C#) Issue with double quotes #2085

Closed dembeck closed 1 year ago

dembeck commented 1 year ago

Bug Description

When I try to add a double quote '"' to a regex pattern it gives one of two errors.

Reproduction steps

I have also tried using square brackets with the below examples, but they do not have any impact on this issue.

Double Quote

Set flavor to .NET (C#)
Add a double quote character " to a regex pattern.
Receive the error: " An unescaped delimiter must be escaped; in most languages with a backslash (\)

Escaped Double Quote

Set flavor to .NET (C#)
Add an escaped double quote character \" to a regex pattern.
Receive the error: \" This token has no special meaning and has thus been rendered erroneous

PowerShell Escaped Double Quote

Set flavor to .NET (C#)
Add a PowerShell escaped double quote character `" to a regex pattern.
Receive the error: " An unescaped delimiter must be escaped; in most languages with a backslash (\)

Expected Outcome

That it handles double quotes correctly.

Hi @dembeck

TL;DR: use "" to escape a double quote in a raw .NET string aka @"..."
