Ejemplo
The example runs a Server object enumeration method, but extracting the information from the DataTable object is the same for Database enumeration methods.
'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Call the EnumCollations method and return collation information to DataTable variable.
Dim d As DataTable
'Select the returned data into an array of DataRow.
d = srv.EnumCollations
'Iterate through the rows and display collation details for the instance of SQL Server.
Dim r As DataRow
Dim c As DataColumn
For Each r In d.Rows
Console.WriteLine("============================================")
For Each c In r.Table.Columns
Console.WriteLine(c.ColumnName + " = " + r(c).ToString)
