or

<pre><code>s = s.Replace(@"""", @"\""");
</code></pre>

In the first example the <code>"</code> has to be escaped with a backslash as it would otherwise end the string. Likewise, in the replacement string <code>\\</code> is needed to yield a single backslash by escaping the escape character.

In the second example verbatim string literals are used, they are written as <code>@"..."</code>. In those literals no escape sequences are recognized, allowing you to write strings that contain lots of backslashes in a much cleaner way (such as regular expressions). The only escape sequence that works there is <code>""</code> for a single <code>"</code>.

How to replace the below string in C#

Current:

<pre><code>"John K "GEN" Greg"
</code></pre>

The Goal:

<pre><code> "John K \"GEN\" Greg"
</code></pre>

This is wrong because I'm not escaping it properly:

<pre><code>s = s.Replace(""","\"");
</code></pre>

What is syntax for replacing quotes with \ (slash)?

Any help would be appreciated.

Thanks
