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}
