The following code example adds a variable to the package. The code example uses various methods to locate the variable and print its name, value, and namespace.
using System; using System.Collections.Generic; using System.Text; using Microsoft.SqlServer.Dts.Runtime; namespace Adding_Variables { class Program { static void Main(string[] args) { Application app = new Application(); // Load a sample package that contains a variable that sets the file name. Package pkg = app.LoadPackage(@"C:\Program Files\Microsoft SQL Server\90\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx", null); Variables pkgVars = pkg.Variables; Variable myVar = pkg.Variables.Add("myCustomVar", false, "User", "3"); // Verify whether the variable is in the collection now. Boolean hasMyVar = pkg.Variables.Contains("myCustomVar"); Console.WriteLine("The variable was found? {0}", hasMyVar); // Loop over the collection using the foreach keyword. foreach (Variable pkgVar in pkgVars) { // Print variables only from the User namespace. if (pkgVar.Namespace == "User") { Console.WriteLine("Variable: {0}, {1}", pkgVar.Name, pkgVar.Value.ToString()); } } Console.WriteLine("---------------------------"); // Loop over the collection using the Enumerator. VariableEnumerator myEnum = pkg.Variables.GetEnumerator(); int i = 0; while ((myEnum.MoveNext()) && (myEnum.Current != null)) // Again, show variables only from the User namespace. if (myEnum.Current.Namespace == "User") { Console.WriteLine("[{0}] {1}, {2}", i++, myEnum.Current.Name, myEnum.Current.Namespace); } myEnum.Reset(); Console.WriteLine("---------------------------"); //Using the Item method syntax of [x], obtain the // first entry in the collection. myVar = pkgVars[0]; Console.WriteLine("The name and namespace of the first variable is: {0}, {1}", myVar.Name, myVar.Namespace); String nameOfFirstItem = pkgVars[0].Name; Console.WriteLine("The name of the first variable is: {0}", nameOfFirstItem); //} } } }
Sample Output:
The variable was found? True
Variable: myCustomVar, 3
---------------------------
[0] myCustomVar, User
---------------------------
The name and namespace of the first variable is: CancelEvent, System
The name of the first variable is: CancelEvent
