Syntax

public static Dictionary<string, List<string>> FindSymbols(this string symbols)

public Dictionary<string, List<string>> 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<string, List<string>> result = symbols.FindSymbols();
			
			foreach( KeyValuePair<string, List<string>> 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);
			}
		}
	}
}
