DocumentBase.PasswordEncryptionFileProperties 属性
定义
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
获取一个值，用于指示 Microsoft Office Word 是否对受密码保护的文档的文件属性进行加密。
public bool PasswordEncryptionFileProperties { get; }属性值
如果 Microsoft Office Word 对受密码保护的文档的文件属性进行加密，则为 true；否则为 false。
示例
如果未对受密码保护的文档的文件属性进行加密，下面的代码示例将设置密码加密选项。 若要使用此示例，请在 ThisDocument 文档级项目的类中运行它。
private void DocumentPasswordEncryptionFileProperties()
{
if (this.PasswordEncryptionFileProperties == false)
{
string PasswordEncryptionProvider = "Microsoft RSA SChannel Cryptographic Provider";
string PasswordEncryptionAlgorithm = "RC4";
int PasswordEncryptionKeyLength = 56;
object PasswordEncryptionFileProperties = true;
this.SetPasswordEncryptionOptions(PasswordEncryptionProvider,
PasswordEncryptionAlgorithm, PasswordEncryptionKeyLength,
ref PasswordEncryptionFileProperties);
}
}
Private Sub DocumentPasswordEncryptionFileProperties()
If Me.PasswordEncryptionFileProperties = False Then
Dim PasswordEncryptionProvider As String = _
"Microsoft RSA SChannel Cryptographic Provider"
Dim PasswordEncryptionAlgorithm As String = "RC4"
Dim PasswordEncryptionKeyLength As Integer = 56
Dim PasswordEncryptionFileProperties As Object = True
Me.SetPasswordEncryptionOptions(PasswordEncryptionProvider, PasswordEncryptionAlgorithm, PasswordEncryptionKeyLength, PasswordEncryptionFileProperties)
End If
End Sub
注解
使用 SetPasswordEncryptionOptions 方法指定 Word 是否对受密码保护的文档的文件属性进行加密。
