In this article we are going to see how to get a database List dynamically using C#.Step 1: Used Namespacesusing System.Web.Configuration;using System.Data.SqlClient;using Microsoft.SqlServer.Management.Common;using Microsoft.SqlServer.Management.Smo;Step 2: Referenced DLLStep 3: Connection String:<add name="<KEY>" connectionString="Data Source=<SERVERNAME>;Initial Catalog=<DATABASE>;Integrated Security=True" />Step 4: Used to get Connection String from Web.config file:public static string GetConnectionStringFromWebConfigByName(string name){ return WebConfigurationManager.ConnectionStrings[name].ConnectionString;}Step 5: UsageDatabaseCollection databases = SQLDatabaseClass .DbCollection(connectionString);Here you can get the collection of a database as a List.Database database = SQLDatabaseClass.SinglDatabase(connectionString);Here you can get a single database by its name.Step 6: Creating Connection String for server connection:public static SqlConnection Connecection(string connectionString){ SqlConnection con = new SqlConnection(connectionString); return con;}Step 7: Creating Server connection using Connection string:public static ServerConnection GetServerConnection(string connectionString){ ServerConnection serverCon = new ServerConnection(Connecection(connectionString)); serverCon.Connect(); return serverCon;}Step 8: Creating Server Object:public static Server GetServer(string connectionString){ Server server = new Server(GetServerConnection(connectionString)); return server;}Step 9: Getting Database collection from the SQL Server:public static DatabaseCollection DbCollection(string connectionString){ Server server = GetServer(connectionString); return server.Databases;}Step 10: Getting a specific database from the collection of databases in the SQL Server:public static Database SinglDatabase(string connectionString, string databaseName){ return GetServer(connectionString).Databases[databaseName];}Code Snippet:class SQLDatabaseClass{ #region Database public static DatabaseCollection DbCollection(string connectionString) { Server server = GetServer(connectionString); return server.Databases; } public static Database SinglDatabase(string connectionString, string Name){ return GetServer(connectionString).Databases[databaseName];} #endregion public static Server GetServer(string connectionString){ Server server = new Server(GetServerConnection(connectionString)); return server;}
public static ServerConnection GetServerConnection(string connectionString){ ServerConnection serverCon = new ServerConnection(Connecection(connectionString)); serverCon.Connect(); return serverCon;}
public static ServerConnection GetServerConnectionByLogin(bool isWindows, string serverName) { ServerConnection serverCon = new ServerConnection(); serverCon.LoginSecure = isWindows; serverCon.ServerInstance = serverName; serverCon.Connect(); return serverCon; }
public static SqlConnection Connecection(string connectionString) { SqlConnection con = new SqlConnection(connectionString); return con; }}Thanks for reading this article. Have a nice day.
