Body
I'm trying to do a simple string generation based on pattern. My idea was to use Regex to do simple replace. I've started with simple method: <pre><code>private static string parseTemplate(string template) { return Regex.Replace(template, @"(\[d)((:)?([\d]+)?)\]", RandomDigit()); } private static string RandomDigit() { Random r = new Random(); return r.Next(0, 9).ToString(); } </code></pre> What this does for now is replacing groups like <code>[d]</code>, <code>[d:3]</code> with what supposed to be random digit. Unfortunately every group is replaced with the same digit, for example if I put <code>test [d][d][d:3]</code> my method will return <code>test 222</code>. I would like to get different digit in every place, like <code>test 361</code>. Second problem I have is way to handle length: right now I must specify <code>[d]</code> for every digit I want, but it would be easier to specify <code>[d:3]</code> and get the same output. I know that there is a project called <a href="https://github.com/moodmosaic/Fare" rel="nofollow">Fare</a>, but I would like to do this without this library For now I only search for <code>[d]</code>, but is this method will work fine there won't be a problem to add other groups for example: <code>[s]</code> for special characters or any other type of patters. Edit1 As it was suggested I changed Random to a static variable like so: <pre><code>private static string parseTemplate(string template) { return Regex.Replace(template, @"(\[d)((:)?([\d]+)?)\]", RandomDigit()); } private static Random r = new Random(); private static string RandomDigit() { return r.Next(0, 9).ToString(); } </code></pre> Problem is that when I call my code like so: <pre><code>Console.WriteLine(parseTemplate("test [d:2][d:][d]")); Console.WriteLine(parseTemplate("test [d:2][d:][d]")); </code></pre> I get output like this <pre><code>test 222 test 555 </code></pre> I would like output like this (for example): <pre><code>test 265 test 962 </code></pre> I think that problem is with <code>Regex.Replace</code> which calls my <code>RandomDigit</code> only once.

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.
