Я вызываю пакет служб SSIS из своего пользовательского интерфейса (WPF) через асинхронный вызов службы WCF. Сервисный код:
public string ImportMarriageXML(bool isWakeUp, bool clearExistingMarriage)
{
try
{
var dts = new Microsoft.SqlServer.Dts.Runtime.Application();
using (var package = dts.LoadFromSqlServer(
ServiceSettings.Settings.SSIS.ImportMarriages,
ServiceSettings.Settings.SSIS.ServerIP,
ServiceSettings.Settings.SSIS.UserID,
ServiceSettings.Settings.SSIS.Password,
null))
{
package.InteractiveMode = false;
package.Connections["DB.STAGING"].ConnectionString = String.Format("{0};Provider={1};", DBSettings.ConnectionString(Core.Database.Staging), ServiceSettings.Settings.SSIS.Provider);
var variables = package.Variables;
variables["IsWakeUp"].Value = isWakeUp;
variables["ClearExistingMarriage"].Value = clearExistingMarriage;
variables["XmlDirectory"].Value = ServiceSettings.Settings.SSIS.Properties.XmlDirectory;
if (package.Execute() == DTSExecResult.Failure)
{
// HACK: Need to refactor this at some point. Will do for now.
var errors = new System.Text.StringBuilder();
foreach (var error in package.Errors)
errors.AppendFormat("SubComponent: {0}; Description: {1}{2}", error.SubComponent, error.Description, Environment.NewLine);
throw new ApplicationException(errors.ToString());
}
return package.Connections["Text Logging"].ConnectionString;
}
}
}
И (часть) клиентского кода выглядит следующим образом:
private void InvokeLoadMarriages()
{
integrationServicesServiceClient.BeginImportMarriageXML(false, OnEndImportMarriageXML, null);
}
private void OnEndImportMarriageXML(IAsyncResult asyncResult)
{
view.InvokeDisplayResults(integrationServicesServiceClient.EndImportMarriageXML(asyncResult));
}
Где BeginImportMarriageXML & EndImportMarriageXML - сгенерированные асинхронные операции в прокси-классе.
