难以构建XML-RPC.NET客户端(要与Moodle一起使用)

Question

我正在使用CookComputing XML来构建一个C#控制台客户端，以便在Moodle (一个开放源代码的学习管理系统)上执行C#方法。服务器正在使用。

当我运行代码时，我得到一个TypeLoadException是未处理的，它指的是以下一行：

System.Object myResults = proxy.moodle_user_get_user_by_id(myUserIds);

“重写成员时违反了继承安全规则:重写方法的'CookComputing.XmlRpc.XmlRpcFaultException.GetObjectData(System.Runtime.Serialization.SerializationInfo，System.Runtime.Serialization.StreamingContext)'.安全可访问性必须与被覆盖的方法的安全可访问性相匹配。”

我的客户端代码是：

...
using CookComputing.XmlRpc;


[XmlRpcUrl("http://moodle.ourcompany.com/webservice/xmlrpc/server.php?wstoken=somereallylongtokenstring")]
public interface IMoodleUserGetUsersById : IXmlRpcProxy
{
    [XmlRpcMethod("moodle_user_get_users_by_id")]
    System.Object moodle_user_get_user_by_id(int[] userIds);
}

namespace Moodle_test_api1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Testing XML-RPC Services for Moodle!");

            IMoodleUserGetUsersById proxy = XmlRpcProxyGen.Create<IMoodleUserGetUsersById>();

        int[] myUserIds = {11, 12};
        System.Object myResults = proxy.moodle_user_get_user_by_id(myUserIds);

        //Console.WriteLine("Trying Function: {0}:{1}", proxy.ToString());
    }
  }

}

我想使用的方法的API文档是：

moodle_user_get_users_by_id: Get users by id.


Arguments
---------
userids (Required)

General structure

list of ( 
int   //user ID
)

XML-RPC (PHP structure)

[userids] =>
    Array 
        (
        [0] => int
        )

Response:

  General structure
  -----------------
list of ( 
object {
id double   //ID of the user
username string   //Username policy is defined in Moodle security config
firstname string   //The first name(s) of the user
lastname string   //The family name of the user
email string   //An email address - allow email as root@localhost
auth string   //Auth plugins include manual, ldap, imap, etc
confirmed double   //Active user: 1 if confirmed, 0 otherwise
idnumber string   //An arbitrary ID code number perhaps from the institution
lang string   //Language code such as "en", must exist on server
theme string   //Theme name such as "standard", must exist on server
timezone string   //Timezone code such as Australia/Perth, or 99 for default
mailformat int   //Mail format code is 0 for plain text, 1 for HTML etc
description string   //User profile description
descriptionformat int   //User profile description format
city string   //Home city of the user
country string   //Home country code of the user, such as AU or CZ
customfields  Optional //User custom fields (also known as user profil fields)
list of ( 
object {
type string   //The name of the custom field
value string   //The value of the custom field
} 
)} 
)

有什么建议是有帮助的，包括如果我在正确的位置传递标记？

这个问题似乎已经通过使用更新的Visual 2010支持的XML构建来解决，并结合上面建议的适当的安全调整。

Answer 2

TypeLoadException的一个可能原因是将XML-RPC.NET重新构建为.NET 4.0程序集。如果这样做，您需要包括以下代码：

[assembly: SecurityRules(SecurityRuleSet.Level1)]

这将.NET 2安全透明规则应用于程序集。

Answer 3

向AssemblyInfo.cs添加上述附加信息在以下情况下对我有效：- Visual 2010 -XML-rpc.net的目标框架: 4.0 (完整，非客户端)-XML版本: v2.5.0
