SNMP#Net KeyValuePair错误？

Question

我使用的是下面这个简单的例子，id=102

并有以下代码：

using SnmpSharpNet;
using System;
using System.Collections.Generic;

namespace SNMP
{
    class Program
    {
        static void Main(string[] args)
        {
            string host = "10.65.10.17";
            string community = "public";
            SimpleSnmp snmp = new SimpleSnmp(host, community);

            if (!snmp.Valid)
            {
                Console.WriteLine("SNMP agent host name/ip address is invalid.");
                return;
            }
            Dictionary<Oid, AsnType> result = snmp.Get(SnmpVersion.Ver1,
                                                      new string[] { ".1.3.6.1.4.1.11.2.3.9.4.2.1.1.16.1.1.1.26.0" });
            if (result == null)
            {
                Console.WriteLine("No results received.");
                return;
            }

            foreach (KeyValuePair kvp in result)
            {
                Console.WriteLine("{0}: {1} {2}", kvp.Key.ToString(),
                                      SnmpConstants.GetTypeName(kvp.Value.Type),
                                     kvp.Value.ToString());
            }
        }
    }
}   

当我试图建造的时候

Using the generic type 'System.Collections.Generic.KeyValuePair<TKey,TValue>' requires 2 type arguments 

我是不是漏掉了推荐信？还是需要对.net 4.5和VS2013进行调整？

谢谢

您可以提供类型参数：

foreach (KeyValuePair<Oid,AsnType> kvp in result)
{
   Console.WriteLine("{0}: {1} {2}", kvp.Key.ToString(),
                SnmpConstants.GetTypeName(kvp.Value.Type),
                kvp.Value.ToString());
}

或者让编译器执行类型推断：

foreach (var kvp in result)
{
   Console.WriteLine("{0}: {1} {2}", kvp.Key.ToString(),
                SnmpConstants.GetTypeName(kvp.Value.Type),
                kvp.Value.ToString());
}
