MSSqlConnectionProvider.GetConnectionString(String, String) Method

Returns a connection string used to open a specified Microsoft SQL database using Windows Integrated Security.

Namespace: DevExpress.Xpo.DB

Assembly: DevExpress.Xpo.v24.2.dll

Declaration

C#

public static string GetConnectionString(
    string server,
    string database
)

VB.NET

Public Shared Function GetConnectionString(
    server As String,
    database As String
) As String

Parameters

Name	Type	Description
server	String	A string that specifies the SQL server name.
database	String	A string that specifies the database name.

Returns

Type	Description
String	A connection string.

Remarks

The value returned by this method can be used to initialize a Session’s connection string (for instance, via the Session.ConnectionString or XpoDefault.ConnectionString property).

Note

The string returned by the GetConnectionString method contains an extra parameter that identifies the database type to which a connection should be established, so it’s not fully compatible with the standard connection string format. When a Session receives this connection string, it removes this extra parameter and then passes the valid connection string to the database.

Example

The following code demonstrates how to connect to an Microsoft SQL database. The MSSqlConnectionProvider.GetConnectionString method is called to construct a connection string to the database. It is then assigned to the default session via the Session.ConnectionString property.

C#

using DevExpress.Xpo;
using DevExpress.Xpo.DB;

Session.DefaultSession.ConnectionString = MSSqlConnectionProvider.GetConnectionString(
    "SERVER", "sa", "", "Northwind");

VB.NET

Imports DevExpress.Xpo
Imports DevExpress.Xpo.DB

Session.DefaultSession.ConnectionString = MSSqlConnectionProvider.GetConnectionString( _
    "SERVER", "sa", "", "Northwind")
