Exemplos
The following code example adds a variable to an empty package. The variable is named myCustomVar, is given a value of 3, and is located in the User namespace. The variable is then removed using the Remove method.
using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
namespace Add_Remove_Vars
{
class Program
{
static void Main(string[] args)
{
Package pkg = new Package();
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);
Console.WriteLine("---------------------------");
// 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("---------------------------");
// Remove the variable from the namespace.
pkg.Variables.Remove("myCustomVar");
// Loop over the collection again.
foreach (Variable pkgVar in pkgVars)
{
// Print variables only from the User namespace. Nothing should show.
if (pkgVar.Namespace == "User")
{
Console.WriteLine("Variable: {0}, {1}", pkgVar.Name, pkgVar.Value.ToString());
}
}
Console.WriteLine("---------------------------");
Console.WriteLine("");
