The SMO enumeration URN contains four parts. First is the string, RuntimeServer. followed by a connection. The following line of code is an example of an EnumURN property where a connection has been specified.
RuntimeServer[@Connection='{B1552E8D-43AE-44B1-B5D3-03C4F5461977}']/Server[@Name='localhost']/SMOEnumObj[@Name='Databases']/SMOEnumType[@Name='Names']
The second part of the string is the server name parameter.
The last two parts of the string are the SMOEnumObj and SMOEnumType parameters. The SMOEnumObj parameter, which comes third in the four-part string, describes which enumeration object is enumerated. Valid values are:
@"LinkedServers"
@"Jobs"
@"Logins"
@"Databases"
@"FileGroups"
@"DataFiles"
@"LogFiles"
@"StoredProcedures"
@"UserDefinedDataTypes"
@"UserDefinedFunctions"
@"Views"
@"Users"
@"Tables"
@"Columns"
@"ForeignKeys"
@"Triggers
The code sample above shows an enumeration over databases.
The fourth and final part of the configuration string is the SMOEnumType parameter, which specifies the enumeration type to use. Valid values are:
@"Objects"
@"ObjectsPP"
@"Names"
@"URNs"
@"Locations"
The code sample above enumerates using names.

The ForEachSMOEnumerator object is created and hosted by a ForEachEnumeratorHost. The following code example shows how to create a ForEachSMOEnumerator within the host object.

// When the SMO enumerator is found, set the info variable.
