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

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。
适用于
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
Public Sub New (state As PermissionState, allowBlankPassword As Boolean)

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。
