Retrieving the View Listing
To retrieve the Views schema collection, call the GetSchema method of the CassandraConnection class, as shown in the following examples.

String connectionString = "Database=MyCassandraDB;Port=9042;Server=127.0.0.1;"; using (CassandraConnection conn = new CassandraConnection(connectionString)) { conn.Open(); DataTable databaseSchema = conn.GetSchema("Views"); foreach (DataRow row in databaseSchema.Rows) { Console.WriteLine(row["TABLE_NAME"]); } }
VB.NET
Dim connectionString As String = "Database=MyCassandraDB;Port=9042;Server=127.0.0.1;" Using conn As New CassandraConnection(connectionString) conn.Open() Dim databaseSchema As DataTable = conn.GetSchema("Views") For Each row As DataRow In databaseSchema.Rows Console.WriteLine(row("TABLE_NAME")) Next End Using
