SNMP#Net KeyValuePair error?

本文关键字：error KeyValuePair SNMP#Net | 更新日期: 2023-09-27 18:04:45

我使用这里的简单示例http://www.snmpsharpnet.com/?page_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());
            }
        }
    }
}

当试图构建时，我得到

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

我是否错过了某个地方的引用?或者该示例是否需要为。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());
}
