Run SSIS Package through winforms - winforms

Question

I need to run a SSIS package through winforms.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Deployment;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Runtime.Wrapper;
using System.Net.Mime;
public string sPackage = String.Empty;
public string sConfig = String.Empty;
private void Form1_Load(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog fDialog = new OpenFileDialog();
fDialog.Title = "Open Package";
fDialog.Filter = "SSIS Package (*.dts, *.dtsx)|*.dts;*.dtsx";
fDialog.InitialDirectory = #"C:\";
sPackage = fDialog.FileName.ToString();
}
private void button2_Click(object sender, EventArgs e)
{
OpenFileDialog fDialog = new OpenFileDialog();
fDialog.Title = "Open Package";
fDialog.Filter = "SSIS Package (*.dts, *.dtsx)|*.dts;*.dtsx";
fDialog.InitialDirectory = #"C:\";
sConfig = fDialog.FileName.ToString();
}
private void button3_Click(object sender, EventArgs e)
{
Microsoft.SqlServer.Dts.Runtime.Wrapper.Application app = new Microsoft.SqlServer.Dts.Runtime.Wrapper.Application();
Package package = app.LoadPackage(sPackage,false,null);
package.ImportConfigurationFile(sConfig);
DTSExecResult result = package.Execute();
MessageBox.Show(result.ToString());
}
But this is giving me error at LoadPackage(sPackage,false,null)
Cannot implicitly convert type 'Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSPackage90' to 'Microsoft.SqlServer.Dts.Runtime.Wrapper.Package'. An explicit conversion exists (are you missing a cast?)

Answer 1

I figured out that button3_click should be handled like this
private void button3_Click(object sender, EventArgs e)
{
MyEventListener eventListener = new MyEventListener();
Microsoft.SqlServer.Dts.Runtime.Application app = new Microsoft.SqlServer.Dts.Runtime.Application();
Microsoft.SqlServer.Dts.Runtime.Package pkg = app.LoadPackage(sPackage, eventListener,false);
Microsoft.SqlServer.Dts.Runtime.DTSExecResult pkgResults = pkg.Execute(null, null, eventListener, null, null);
MessageBox.Show(pkgResults.ToString());
}
class MyEventListener : DefaultEvents
{
public override bool OnError(DtsObject source, int errorCode, string subComponent,
string description, string helpFile, int helpContext, string idofInterfaceWithError)
{
// Add application-specific diagnostics here.
MessageBox.Show("Error in " + "/t" + source + "/t" + subComponent + "/t" + description);
return false;
}
}
