Sample Output:

Log providers available in the Package:

DTS.LogProviderTextFile.1

DTS.LogProviderSQLProfiler.1

DTS.LogProviderEventLog.1

DTS.LogProviderTextFile.1

Selected Log Providers for Package: 2

DTS.LogProviderTextFile.1

DTS.LogProviderEventLog.1

Count after one has been removed 1

Index zero in collection contains: DTS.LogProviderTextFile.1

The collection contains the following values:

{9A4FD6D3-7DE2-43AD-8B02-CE9B02E7504B}

{AB1C156F-8018-4063-A1A5-48E122CE6FFD}
