Public Property ConnectionString As String

Property Value

Type	Description
String	A string value which specifies the parameters needed to establish the initial connection.

Remarks

The default connection string provides connection to the SQL Server. You can specify another connection string. For this purpose, use the Application Designer or configuration file. In configuration files, a connection string is specified in the connectionStrings section. You can specify a connection string for development and other compilation modes. In this instance, set the ConnectionString property in the following manner:

C#

static class Program {
   static void Main() {
      //...
      MySolutionWindowsFormsApplication application = new MySolutionWindowsFormsApplication();
      application.ConnectionString = 
         ConfigurationManager.ConnectionStrings["ConnectionStringForDevelopment"].ConnectionString;
      //...
      application.Setup();
      //...
   }
}

VB.NET

Friend Class Program
   Private Sub New()
   End Sub
   Shared Sub Main()
      '...
      Dim _application As MySolutionWindowsFormsApplication = 
      New MySolutionWindowsFormsApplication()
      _application.ConnectionString = _
         ConfigurationManager.ConnectionStrings("ConnectionStringForDevelopment").ConnectionString
      '...
      _application.Setup()
      '...
   End Sub
End Class
