在带有命名组的正则表达式中不会发生预期结果

Question

I have this template:

Dear @Model["ClientName"] <br><br>

           Thank you for applying to open an account. Your request for a (@Model["AccountType"]/@Model["Platform"]/@Model["Currency"]) has been sent to our Client team. They are currently reviewing your request.<br><br>

Kind regards,<br>
<a href="mailto:test@example.com">test@example.com</a><br />
+55 00 0000 0000 <br>08:00-18:00 Mon-Fri

And would like to replace all @Model["key"] with a string value.

I have this regex:

const string pattern = @".*(?<model>@Model\[\u0022(?<key>\w+)\u0022\]).*";
var matches = Regex.Matches(input, pattern, RegexOptions.IgnoreCase);

When I check the matches collection I find only 2, ClientName and Currency.

Why is that? I was expecting to find AccountType and Platform too.

Can you help me to identify what is wrong?

Answer 1

Try this match pattern (without the .* before and after):

const string pattern = @"(?<model>@Model\[\u0022(?<key>\w+)\u0022\])";

This will stop the .* from greedily swallowing the whole line, and considering it to be a single match.
