Gets or sets a Boolean value that indicates whether security-sensitive information, such as the password, is returned as part of the connection if the connection is open or has ever been in an open state.

public:
 property bool PersistSecurityInfo { bool get(); void set(bool value); };
public bool PersistSecurityInfo { get; set; }
member this.PersistSecurityInfo : bool with get, set
Public Property PersistSecurityInfo As Boolean

Property Value

Boolean

The value of the PersistSecurityInfo property, or false if none has been supplied.

Examples

The following example works with the PersistSecurityInfo property in two ways. First, it assigns a value directly to the property, demonstrating the effect this action has on the resulting connection string. Then, the example clears the OleDbConnectionStringBuilder and assigns a complete connection string that contains a value for the "Persist Security Info" key. This step demonstrates that setting the value from the connection string modifies the PersistSecurityInfo property, as well.

using System.Data.OleDb;

class Program
{
    static void Main()
    {
        OleDbConnectionStringBuilder builder =
            new OleDbConnectionStringBuilder();
        builder.PersistSecurityInfo = true;
        builder.Provider = "Microsoft.Jet.Oledb.4.0";
        builder.DataSource = @"C:\Sample.mdb";

        // Store the connection string.
        string savedConnectionString = builder.ConnectionString;
        Console.WriteLine(savedConnectionString);

        // Reset the object. This resets all the properties to their
        // default values.
        builder.Clear();

        // Investigate the PersistSecurityInfo property before
        // and after assigning a connection string value.
        Console.WriteLine("Default : " + builder.PersistSecurityInfo);
        builder.ConnectionString = savedConnectionString;
        Console.WriteLine("Modified: " + builder.PersistSecurityInfo);

        Console.WriteLine("Press Enter to finish.");
        Console.ReadLine();
    }
}

Imports System.Data.OleDb    

Module Module1
  Sub Main()
    Dim builder As New OleDbConnectionStringBuilder()
    builder.PersistSecurityInfo = True
    builder.Provider = "Microsoft.Jet.Oledb.4.0"
    builder.DataSource = "C:\Sample.mdb"

    ' Store the connection string.
    Dim savedConnectionString As String = builder.ConnectionString
    Console.WriteLine(savedConnectionString)

    ' Reset the object. This resets all the properties to their
    ' default values.
    builder.Clear()

    ' Investigate the PersistSecurityInfo property before
    ' and after assigning a connection string value.
    Console.WriteLine("Default : " & builder.PersistSecurityInfo)
    builder.ConnectionString = savedConnectionString
    Console.WriteLine("Modified: " & builder.PersistSecurityInfo)

    Console.WriteLine("Press Enter to finish.")
    Console.ReadLine()
  End Sub
End Module

Remarks

This property corresponds to the "Persist Security Info" key within the connection string.
