Get list of database depends on chosen server

Question

I\'m using C# with framework 4.0 and SQL server 2008 R2. I have listed the SQL server 2008 with this code:

 public static string[] GetSQLServerList()
        {
          


        

Answer 1

This is how you get a list of server names on the network:

List<String> ServerNames = new List<String>();

 SqlDataSourceEnumerator servers = SqlDataSourceEnumerator.Instance;
 DataTable serversTable = servers.GetDataSources();

     foreach (DataRow row in serversTable.Rows) {
            string serverName = row[0].ToString();

             try {

                if (row[1].ToString() != "") {

                            serverName += "\\" + row[1].ToString();

                }


              }
              catch {


              }

              ServerNames.Add(serverName);
      }

To Get a List of databases from selected server:

List<String> databases = new List<String>();

SqlConnectionStringBuilder connection = new SqlConnectionStringBuilder();

 connection.DataSource = SelectedServer;
 // enter credentials if you want
 //connection.UserID = //get username;
// connection.Password = //get password;
 connection.IntegratedSecurity = true;

 String strConn = connection.ToString();

 //create connection
  SqlConnection sqlConn = new SqlConnection(strConn);

//open connection
sqlConn.Open();

 //get databases
DataTable tblDatabases = sqlConn.GetSchema("Databases");

//close connection
sqlConn.Close();

//add to list
foreach (DataRow row in tblDatabases.Rows) {
      String strDatabaseName = row["database_name"].ToString();

       databases.Add(strDatabaseName);


}

    using (var connection = new System.Data.SqlClient.SqlConnection("ConnectionString"))
    {
        connection.Open();
        var command = new System.Data.SqlClient.SqlCommand();
        command.Connection = connection;
        command.CommandType = CommandType.Text;
        command.CommandText = "SELECT name FROM master.sys.databases";

        var adapter = new System.Data.SqlClient.SqlDataAdapter(command);
        var dataset = new DataSet();
        adapter.Fill(dataset);
        DataTable dtDatabases = dataset.Tables[0];
    }
