    <p>It's not clear to me if this example represents a potential infinite nesting of these JSON-esque groups, or just one level of nesting.</p> <p>If only one level of nesting is possible, a straightforward Regex will do:</p> <p>(Please note I did not write this with an IDE; the concept should be correct but syntax errors can't be guaranteed at the moment. Apologies)</p> <pre><code>string pattern = @"(?&lt;key&gt;)[A-Z]+)\s(?&lt;value&gt;({.+?}|[^{},]+))"; List&lt;string[]&gt; results = new List&lt;string[]&gt;(); //probably not best data structure MatchCollection matches = Regex.Matches(input, pattern, RegexOptions.SingleLine | RegexOptions.IgnoreCase); foreach(Match match in matches) { if(match.Success) { results.Add(new string[] { match.Groups["key"].Value, match.Groups["value"].Value }); } } </code></pre> <p>If they can be nested many levels, you probably want to approach this recursively. That would necessitate splitting the value match into nested value and simple value:</p> <pre><code>string pattern = @"(?&lt;key&gt;)[A-Z]+)\s({(?&lt;nested&gt;.+?)}|(?&lt;simple&gt;[^{},]+))"; </code></pre> <p>And for each match where nested has a value, execute the same routine against that value:</p> <pre><code>void Deserialize(string input, List&lt;string[]&gt; values) { MatchCollection matches = Regex.Matches(input, pattern, RegexOptions.SingleLine | RegexOptions.IgnoreCase); foreach(Match match in matches) { if(match.Success) { if(match.Groups["nested"].Success &amp;&amp; !string.IsNullOrEmpty(match.Groups["nested"].Value)) { Deserialize(match.Groups["nested"].Value, values); } else { values.Add(new string[] { match.Groups["key"].Value, match.Groups["simple"].Value }); } } } } </code></pre>

    1. COYes, approaching this recursively is what I was shooting for. I will edit my post and I will try your example. I have never used recursive regex before.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
