Syntax

public static Dictionary> FindSymbols(this string symbols)

public Dictionary> FindSymbols(string symbols)


Parameter Description

symbolsSymbol name (or a list of symbols) to find

Description

Sometimes, you need to know which DataSet(s) contain some particular symbol name(s). This function lets you find DataSets which include a given symbol. Passing a list of symbols is also supported.

When passing multiple symbol names, separate them with one of these characters: comma (','), semicolon (';'), or space (' '). (Consequently, space couldn't be a part of the symbol name.)

A Dictionary is returned, where the Key collection contains symbol name(s), and the Value collection contains the list of DataSet names where a corresponding symbol name was found.

Example

Check out this example which makes the function's usage easy:

Example using C# extension methods:

using System; using System.Windows.Forms; using System.Collections; using System.Collections.Generic; using System.Text; using System.Drawing; using WealthLab;

namespace WealthLab.Strategies { public class SearchForClickedSymbol : WealthScript { protected override void Execute() { ClearDebug();

// Dialog to manually input some symbol(s) string symbols = this.Input(); // FindSymbols output Dictionary> result = symbols.FindSymbols(); foreach( KeyValuePair> kvp in result ) { //Looping by each symbol... PrintDebug("Symbol: " + kvp.Key); // ...display every DataSet found foreach( string ds in kvp.Value ) PrintDebug("DataSet name: " + ds); } } } }


Legacy syntax example:

using System; using System.Windows.Forms; using System.Collections; using System.Collections.Generic; using System.Text; using System.Drawing; using WealthLab; using Community.Components; /*** Requires installation of Community.Components Extension from www.wealth-lab.com > Extensions ***/

namespace WealthLab.Strategies { public class SearchForClickedSymbol : WealthScript { protected override void Execute() { Utility u = new Utility(this); ClearDebug();

// Dialog to manually input some symbol(s) string symbols = Utility.Input(); // FindSymbols output Dictionary> result = new Dictionary>(); result = u.FindSymbols(symbols); foreach( KeyValuePair> kvp in result ) { //Looping by each symbol... PrintDebug("Symbol: " + kvp.Key); // ...display every DataSet found foreach( string ds in kvp.Value ) PrintDebug("DataSet name: " + ds); } } } }
