Body
I would use the String.Split(char[]) method and the String.SubString(int, int) method to inspect every 'country' inside your array and to get the number postfix of each country. Try the following: (The following code is now compiled and tested.) Use a simple data structure to facilitate the task of holding the result of your operation. <pre><code>public struct Result { string Country { get; set; } int Number { get; set; } int Occurrences { get; set; } } // define what countries you are dealing with string[] countries = new string[] { "Pakistan", "India", "USA", "Iran", "UK", } </code></pre> Method to provide the overall result: <pre><code>public static Result[] IterateOverAllCountries () { // range of numbers forming the postfix of your country strings int numbersToLookFor = 4; // provide an array that stores all the local results // numbersToLookFor + 1 to respect that numbers are starting with 0 Result[] result = new Result[countries.Length * (numbersToLookFor + 1)]; string currentCountry; int c = 0; // iterate over all countries for (int i = 0; i < countries.Length; i++) { currentCountry = countries[i]; int j = 0; // do that for every number beginning with 0 // (according to your question) int localResult; while (j <= numbersToLookFor) { localResult = FindCountryPosition(currentCountry, j); // add another result to the array of all results result[c] = new Result() { Country = currentCountry, Number = j, Occurrences = localResult }; j++; c++; } } return result; } </code></pre> Method to provide a local result: <pre><code>// iterate over the whole array and search the // occurrences of one particular country with one postfix number public static int FindCountryPosition (string country, int number) { int result = 0; string[] subArray; for (int i = 0; i < arr1.Length; i++) { subArray = arr1[i].Split(','); string current; for (int j = 0; j < subArray.Length; j++) { current = subArray[j]; if ( current.Equals(country + ":" + number) && current.Substring(current.Length - 1, 1).Equals(number + "") ) result++; } } return result; } </code></pre> The following should enable you to run the algorithm <pre><code> // define what countries you are dealing with static string[] countries = new string[] { "Pakistan", "India", "USA", "Iran", "UK", }; static string[] arr1 = new string[] { "Pakistan:4,India:3,USA:2,Iran:1,UK:0", "Pakistan:4,India:3,USA:2,Iran:1,UK:0", "India:4,USA:3,Iran:2,UK:1,Pakistan:0" }; static void Main (string[] args) { Result[] r = IterateOverAllCountries(); } </code></pre>

Guidance

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.
