Question

我正在尝试将联系人写入ADLDS ldap，以便将它们用作Yealink T48G的电话簿。有时，联系人的姓名包括一些特殊字符，如“ö”，“ß”和“é”。如果这些字符包含在“givenName”或“displayName”字段中，则电话和ldap客户端都不能正确显示它们，而是显示其他字符（例如“ö” - >“¶”），但是“名称“和”dn“字段正确显示这些字符。

如果我通过ADSI-Edit或任何其他工具插入联系人值，手机会正确显示名称，但我的应用程序不再能够从givenName读取插入的特殊字符并显示一些问号框，但是dn和名称字段已正确读取。

我已经尝试过使用utf-8，utf-16，utf-32，iso-8859-1和windows-1252作为我的应用程序的编码。

所以问题是如何在ADLDS实例中的inetOrgPerson的givenName属性中使用C＃存储这些特殊字符？

通过设置应该用于版本3的协议版本来解决该问题。

connection = new LdapConnection(new LdapDirectoryIdentifier(host, port));
connection.SessionOptions.ProtocolVersion = 3;
