Loading SSIS package and it's connection managers in a WPF application - wpf

Question

I created an integration service project with three connection managers (which are defined in project level), now I have an SSIS package (.dtsx file) and I want to use it in my app.
So I use Microsoft.SqlServer.Dts namespace as below:
string pkgLocation;
Package pkg;
Microsoft.SqlServer.Dts.Runtime.Application app;
DTSExecResult pkgResults;
pkgLocation = #"D:\My Job\Tadbirgaran\Integration Services Project\MyPackage.dtsx";
app = new Microsoft.SqlServer.Dts.Runtime.Application();
pkg = app.LoadPackage(pkgLocation, null);
pkgResults = pkg.Execute();
but this code does not load project connection managers obviously, so is there any way that I can load connection manager files programmatically and add them to the package connection property? or should I define connections in my package in the integration service project?

Answer 1

You can use configurations to control the connection properties programmatically. Here is an example.
using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Tasks.BulkInsertTask;
namespace configuration_API
{
class Program
{
static void Main(string[] args)
{
// Create a package and set two properties.
Package pkg = new Package();
pkg.EnableConfigurations = true;
pkg.ExportConfigurationFile(#"C:\conf.xml");
// Create a variable object and add it to the
// package Variables collection.
Variable varPkg = pkg.Variables.Add("var", false, "", 100);
varPkg.Value = 1;
string packagePathToVariable = varPkg.GetPackagePath();
// Create a configuration object and add it to the
// package configuration collection.
Configuration config = pkg.Configurations.Add();
// Set properties on the configuration object.
config.ConfigurationString = "conf.xml";
config.Description = "My configuration description";
config.ConfigurationType = DTSConfigurationType.ConfigFile;
config.PackagePath = packagePathToVariable;
// Save the package and its configuration.
Application app = new Application();
app.SaveToXml(#"c:\pkg.xml", pkg, null);
// Reload the package.
Package p1 = app.LoadPackage(#"c:\pkg.xml", null);
// Review the configuration information.
Configurations configs_After = pkg.Configurations;
foreach(Configuration confAfter in configs_After)
{
Console.WriteLine("ConfigurationString is {0}", confAfter.ConfigurationString);
Console.WriteLine("ConfigurationType is {0}", confAfter.ConfigurationType);
Console.WriteLine("CreationName is {0}", confAfter.CreationName);
Console.WriteLine("Description is {0}", confAfter.Description);
Console.WriteLine("Assigned ID is {0}", confAfter.ID);
Console.WriteLine("Name is {0}", confAfter.Name);
}
}
}
}

I ended up loading the project instead of package and setting connections from project to package as below:
private void SSISLoadData()
{
Project ssisProject = null;
DTSExecResult pkgResults;
try
{
ssisProject = Project.OpenProject(#"D:\My Job\TDB\Integration Services Project\bin\Development\Integration Services Project.ispac");
Package pkg = ssisProject.PackageItems[0].LoadPackage(null);
for (int i = 0; i < ssisProject.ConnectionManagerItems.Count; i++)
pkg.Connections.Join(ssisProject.ConnectionManagerItems[i].ConnectionManager);
pkg.Connections[0].ConnectionString = dataFolderPath + "\\*.csv";
pkg.Connections[1].ConnectionString = string.Format("Data Source =.; Initial Catalog = TDB; Provider = SQLNCLI11.1; Integrated Security = SSPI; Initial File Name = {0};", dbPath);
pkg.Connections[2].ConnectionString = string.Format("Data Source =.; Initial Catalog = TDBRawData; Provider = SQLNCLI11.1; Integrated Security = SSPI; Initial File Name = {0}\\TDBRawData.mdf;", Environment.CurrentDirectory);
pkgResults = pkg.Execute();
MessageBox.Show(pkgResults.ToString());
}
catch (Exception e)
{
MessageBox.Show(e.Message);
}
finally
{
if (ssisProject != null)
ssisProject.Dispose();
}
}
I don't know if there is a better solution for this problem, but it works.
