  A .NET application that connects to InterSystems IRIS and uses the Native SDK to access globals, class methods, and routines.	n/a	Begin code: using System; using InterSystems.Data.IRISClient; using InterSystems.Data.IRISClient.ADO; namespace NativeApp { class Program { static void Main(string[] args) { Console.WriteLine("Hello World!"); String port = "51774"; String host = "localhost"; String Namespace = "USER"; String username = "SuperUser"; String password = "SYS"; try { IRISConnection connection = new IRISConnection(); connection.ConnectionString = "Server = " + host + "; Port = " + port + "; Namespace = " + Namespace + "; Password = " + password + "; User ID = " + username; connection.Open(); Console.WriteLine("Connected to InterSystems IRIS."); // Create irisNative object IRIS irisNative = IRIS.CreateIRIS(connection); // Setting and getting a global irisNative.set(967.47, "^stocks", "AMZN"); irisNative.set(50.29, "^stocks", "MSFT"); irisNative.set(159.83, "^ stocks", "TSLA");  Double amznPrice = (double)irisNative.GetDouble ("^stocks", "AMZN"); Console.WriteLine("The current price of AMZN is $" + amznPrice); // Iterating over a global IRISIterator iter = irisNative.GetIRISIterator("^stocks", null); Console.WriteLine("walk forwards"); foreach (var v in iter) { String subscript = (string)iter.CurrentSubscript; Console.WriteLine("The current price of " + subscript + " is $" + iter.Current); } // Calling a class method String newStockName = irisNative.ClassMethodString("%Library.PopulateUtils", "StringMin", 3, 4).ToUpper(); Double newStockPrice = (double)irisNative.ClassMethodDouble("%Library.PopulateUtils", "Float", 0, 1000, 2); irisNative.Set(newStockPrice, "^stocks", newStockName); Console.WriteLine("Created new stock " + newStockName + " at current value $" + newStockPrice); // Calling a routine String irisVersion = (string)irisNative.FunctionString("PrintVersion", "^StocksUtil"); Console.WriteLine("The current version of InterSystems IRIS is " + irisVerion); // Close connection and native object irisNative.Close(); connection.Close(); } catch (Exception ex) { Console.WriteLine(ex.Message); } } } } End code
  ObjectScript equivalent for getting and setting a global	4:20	Begin code: set ^stocks("AMZN") = 1582.32 set ^stocks("MSFT") = 94.18 set ^stocks("TSLA") = 325.61 set amznPrice = $get(^stocks("AMZN")) End code
  ObjectScript code for iterating through global.		Begin code: set subscript = "" for { set sub = $ORDER(^stocks(sub), 1, val) quit:(sub = "") write !, "The current price of ", sub, " is $", val } End code
  ObjectScript equivalent for calling a class method	5:08	Begin code: set newStockName = $ZCONVERT(##class(%PopulateUtils).StringMin(3,4), "U") set newStockPrice = ##class(%PopulateUtils).Float(0,1000,2) set ^stocks(newStockName) = newStockPrice write "Created new stock " _ newStockName _ " at current value $" _ newStockPrice End code
