    <p>I seem to be having a problem with the following file:</p> <pre><code>*User Type 0: Database Administrator Users of this Type: Database Administrator DBA Can Authorise:Y Administrator:Y DM3 Admin Account DM3 Can Authorise:Y Administrator:Y Permissions for these users: Data - Currencies Parameters - Database Add FRA Deal Reports - Confirmation Production Add Currency Amend Database Parameters Cancel FRA Deal Reports - System Printer Definitions Delete Currency Parameters - Data Retention Amend FRA Deal Save System Printers Amend Currency Amend Data Retention Parameters Amend Settlements Only Custom Confs/Tickets Amend Currency Rates Data - Rate References Verify FRA Deal Add Custom Confs/Tickets Amend Currency Holidays Add Rate Reference Add FRA Deal (Restricted) Delete Custom Confs/Tickets Add Nostro Delete Rate Reference Release FRA Deal Amend Custom Confs/Tickets Amend Nostro Amend Rate Reference Deal - IRS Reports - System Report Batches Delete Nostro Deal - Call Accounts Add IRS Deal Save System Batches Data - Currency Pairs Open Call Account Cancel IRS Deal Reports - View Reports Spooled Add Currency Pair Amend Call Account Amend IRS Deal View - Audits Delete Currency Pair Close Call Account Amend Settlements Only Print Audit Amend Currency Pair Amend Settlements Only Verify IRS Deal Print Audit Detail Data - Books Data - Sales Relationship Mgrs Add IRS Deal (Restricted) Filter Audit* </code></pre> <p>I am using a regular expression to check each line for a pattern. In total there are three patterns that need to match. If you look at the first three lines, that is all the information that needs to be taken from the file. The problem im having is that my regex is not matching. Also what needs to be done is the information needs to be taken from between two lines.... How do i do that? </p> <p>This is the code i have so far:</p> <pre><code> string path = @"C:/User Permissions.txt"; string t = File.ReadAllText(path); //Uses regular expression check to match the specified string pattern string pattern1 = @"User Type "; string pattern2 = @"Users of this Type:"; string pattern3 = @"Permissions for these users:"; Regex rgx1 = new Regex(pattern1); Regex rgx2 = new Regex(pattern2); Regex rgx3 = new Regex(pattern3); MatchCollection matches = rgx1.Matches(t); List&lt;string[]&gt; test = new List&lt;string[]&gt;(); foreach (var match in matches) { string[] newString = match.ToString().Split(new string[] { @"User Type ", }, StringSplitOptions.RemoveEmptyEntries); for (int i = 3; i &lt;= newString.Length; i++) { test.Add(new string[] { newString[0], newString[1], newString[i - 1] }); } } MatchCollection matches2 = rgx2.Matches(t); List&lt;string[]&gt; test2 = new List&lt;string[]&gt;(); foreach (var match2 in matches2) { string[] newString = match2.ToString().Split(new string[] { @"Permissions for these users: ", }, StringSplitOptions.RemoveEmptyEntries); for (int i = 3; i &lt;= newString.Length; i++) { test2.Add(new string[] { newString[0], newString[1], newString[i - 1] }); } } MatchCollection matches3 = rgx3.Matches(t); List&lt;string[]&gt; test3 = new List&lt;string[]&gt;(); foreach (var match3 in matches3) { string[] newString = match3.ToString().Split(new string[] { @"Users of this Type: ", }, StringSplitOptions.RemoveEmptyEntries); for (int i = 3; i &lt;= newString.Length; i++) { test3.Add(new string[] { newString[0], newString[1], newString[i - 1] }); } } foreach (var line in test) { Console.WriteLine(line[0]); Console.ReadLine(); } Console.ReadLine(); </code></pre> <p>Guffa's code seems very efficient compared to mine, the only problem i'm having now is how to extract the lines between "Users of this type" and Permissions for these users". How would go about doing this? Obviously checking to see if the name begins on a new line won't help.</p>

    1. COYour source file looks like a txt dump of data from some other application. Have you investigated if there are other - more adequate - ways to receive this information? I mean: This information *smells* as if it is well structured at it's source. Therefore it seems undesirable to keep the data interface so fuzzy

    2. COIf i look at the data file you posted.. i don't think Regular Expression is the way to go.

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.
