SqlConnectionStringBuilder.IntegratedSecurity 屬性

定義

取得或設定布林值,指出是否在連接中指定使用者 ID 和密碼 (false 時) 或目前 Windows 帳戶認證是否用於驗證 (true 時)。

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

屬性值

IntegratedSecurity 屬性的值,如未提供任何值,則為 false

範例

下列範例會轉換現有的連接字串,將其從使用 SQL Server 驗證轉換成使用整合式安全性。 此範例執行工作的方式是從連接字串中移除使用者名稱和密碼,然後設定 IntegratedSecurity 物件的 SqlConnectionStringBuilder 屬性。

注意

這個範例包含了密碼,可示範 SqlConnectionStringBuilder 如何搭配連接字串使用。 我們建議在您的應用程式中使用 Windows 驗證。 如果您必須使用密碼,請勿在您的應用程式中包含硬式編碼的密碼。
