SqlConnectionStringBuilder.IntegratedSecurity 属性

定义

命名空间:

System.Data.SqlClient

程序集:

System.Data.dll

获取或设置一个布尔值，该值指示是否在连接中指定用户 ID 和密码（值为 false 时），或者是否使用当前的 Windows 帐户凭据进行身份验证（值为 true 时）。

public:
 property bool IntegratedSecurity { bool get(); void set(bool value); };

public bool IntegratedSecurity { get; set; }

member this.IntegratedSecurity : bool with get, set

Public Property IntegratedSecurity As Boolean

属性值

Boolean

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

示例

以下示例将现有连接字符串从使用 SQL Server 身份验证转换为使用集成安全性。 该示例通过以下方式来完成此工作：从连接字符串中移除用户名和密码，然后设置 IntegratedSecurity 对象的 SqlConnectionStringBuilder 属性。

注意

该示例包括一个密码以演示 SqlConnectionStringBuilder 如何使用连接字符串。 在您的应用程序中，建议使用 Windows 身份验证。 如果必须使用密码，请不要在你的应用程序中包括硬编码的密码。

注解

此属性与连接字符串内的“Integrated Security”和“trusted_connection”键相对应。
