All Sample Connection String for All database using C#.Net and VB.Net
Connection string for all database.
Here you can find all connection string for all database using C#.Net and VB.NetMicrosoft SQL Server .NET Data Provider (NameSpace : System.Data.SqlClient)
The Microsoft SQL Server .NET Data Provide allows you to connect to a Microsoft SQL Server databases.
Using C#:
using System.Data.SqlClient;
...
SqlConnection SQLConn = new SqlConnection();
SQLConn.ConnectionString = "Data Source=(local);Initial Catalog=myDatabaseName;User ID=myUsername;"Password=myPassword" ;
SQLConn.Open();
...
SQLConn.Close();
Note : If you open the connection, then close the connection. Otherwise the connection does not go back into the connection pool. The SqlDataAdapter will open and close the connection for you when calling it's Fill or Update methods. However if the connection is already open, the SqlDataAdapter will leave it open.
Using VB.NET:
Imports System.Data.SqlClient
...
Dim SQLConn As SqlConnection = New SqlConnection()
SQLConn.ConnectionString = "Data Source=(local);Initial Catalog=myDatabaseName;"User ID=myUsername;Password=myPassword"
SQLConn.Open()
...
SQLConn.Close()
If connect to a remote server (via IP address):
SQLConn.ConnectionString = _
"Network Library=DBMSSOCN;" Data Source=xxx.xxx.xxx.xxx,1433;Initial Catalog=myDatabaseName;User ID=myUsername;Password=myPassword"
SQLConn.Open()
...
SQLConn.Close()ODBC .NET Data Provider (NameSpace : System.Data.Odbc)
