SqlClientPermission()

注意

SqlClientPermission() has been deprecated. Use the SqlClientPermission(PermissionState.None) constructor. http://go.microsoft.com/fwlink/?linkid=14202

初始化 SqlClientPermission 类的新实例。

public:
 SqlClientPermission();

[System.Obsolete("SqlClientPermission() has been deprecated.  Use the SqlClientPermission(PermissionState.None) constructor.  http://go.microsoft.com/fwlink/?linkid=14202", true)]
public SqlClientPermission ();

Public Sub New ()

属性

ObsoleteAttribute

SqlClientPermission(PermissionState)

初始化 SqlClientPermission 类的新实例。

public:
 SqlClientPermission(System::Security::Permissions::PermissionState state);

public SqlClientPermission (System.Security.Permissions.PermissionState state);

new Microsoft.Data.SqlClient.SqlClientPermission : System.Security.Permissions.PermissionState -> Microsoft.Data.SqlClient.SqlClientPermission

Public Sub New (state As PermissionState)

参数

state

PermissionState

PermissionState 值之一。

SqlClientPermission(PermissionState, Boolean)

注意

SqlClientPermission(PermissionState state, Boolean allowBlankPassword) has been deprecated. Use the SqlClientPermission(PermissionState.None) constructor. http://go.microsoft.com/fwlink/?linkid=14202

初始化 SqlClientPermission 类的新实例。

public:
 SqlClientPermission(System::Security::Permissions::PermissionState state, bool allowBlankPassword);

[System.Obsolete("SqlClientPermission(PermissionState state, Boolean allowBlankPassword) has been deprecated.  Use the SqlClientPermission(PermissionState.None) constructor.  http://go.microsoft.com/fwlink/?linkid=14202", true)]
public SqlClientPermission (System.Security.Permissions.PermissionState state, bool allowBlankPassword);

[<System.Obsolete("SqlClientPermission(PermissionState state, Boolean allowBlankPassword) has been deprecated.  Use the SqlClientPermission(PermissionState.None) constructor.  http://go.microsoft.com/fwlink/?linkid=14202", true)>]
new Microsoft.Data.SqlClient.SqlClientPermission : System.Security.Permissions.PermissionState * bool -> Microsoft.Data.SqlClient.SqlClientPermission

注解

PermissionState枚举优先于 AllowBlankPassword 属性。 因此，如果设置为 AllowBlankPasswordfalse，还必须将 设置为 PermissionStateNone 以防止用户使用空密码建立连接。 有关演示如何使用安全要求的示例，请参阅 代码访问安全性和 ADO.NET。
