OleDbConnectionStringBuilder.PersistSecurityInfo 属性

定义

命名空间:

System.Data.OleDb

程序集:

System.Data.OleDb.dll

包:

System.Data.OleDb v9.0.0-rc.2.24473.5

Source:

OleDbConnectionStringBuilder.cs

获取或设置一个布尔值，该值指示如果连接是打开的或者一直处于打开状态，那么安全敏感信息（如密码）是否作为连接的一部分返回。

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

属性值

Boolean

为 PersistSecurityInfo 属性的值，或者，如果未提供任何值，则为 false。

示例

以下示例通过两种方式使用 PersistSecurityInfo 属性。 首先，它直接向 属性赋值，演示此操作对生成的连接字符串的影响。 然后，该示例清除 OleDbConnectionStringBuilder 并分配包含“持久化安全信息”键值的完整连接字符串。 此步骤演示从 连接字符串设置 值也会PersistSecurityInfo修改 属性。

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

注解

此属性对应于连接字符串中的“持久化安全信息”键。
