Question

我从a.dll发送一个值（attrname [5] =“WRM Version”;）来自SendAgentInfo（）它在sp.dll中作为WrmVersion.From接收到这里我将这些值发送到位于data.dll的接口（IResourcePolicy）。但问题是数据没有获得接口'IResourcePolicy'，如果在接口中收到它，它应该在UI中的LISTVIEW中显示（UI.dll中的ResourcePolicySystemsControl.cs0）我所做的编码如下：

code in a.dll

  public void SendAgentInfo()
      {
       string[] attrname = new string[6];
         string[] attrval = new string[6];

       attrname[5] = "WRM Version";
       .
       .
       attrval[5] = Registry.GetValue(@"HKEY_LOCAL_MACHINE\Software\syscon\Single Point Operations Windows Resource Monitor", "CurrentVersion", "0").ToString();
       }

code in sp.dll

      string wrmVersionSPURT = this_event.variableData[5].atr_value;
       .
       .
      IResourcePolicy irp = (IResourcePolicy)
       .
       .
      irp.WrmVersion = wrmVersionSPURT;
       .
       .

 code     data.dll

        public interface IResourcePolicy
   {

             string WrmVersion
      {
          get;
          set;
      }
   }

code     UI.dll



              public new IResourcePolicy Data
         {
            get
            {
               return (IResourcePolicy)base.Data;
            }
         }

       .
       .

        protected override void OnUpdate()
         {
            string func = "ResourcePolicySystemsLVI.OnUpdate";
            try
            {
               if(Data != null)
               {
                  Text = base.Data.Name;
                  if(SubItems.Count == 1)
                  {
                     SubItems.Add(((IResourcePolicy)Data).ResourcePolicyEnabled.ToString());
                     SubItems.Add(((IResourcePolicy)Data).ResourcePolicyCurrent.ToString());
                     SubItems.Add(((IResourcePolicy)Data).WrmVersion.ToString()); 

                  }
                  else
                  {
                     SubItems[1].Text = ((IResourcePolicy)Data).ResourcePolicyEnabled.ToString();
                     SubItems[2].Text = ((IResourcePolicy)Data).ResourcePolicyCurrent.ToString();
                  }
               }
               base.OnUpdate();
            }

您需要有一个实现IResourcePolicy的类，它将以某种方式分配给UI.dll中的属性Data。注意，接口不是对象;它只描述了实现它的类所期望的接口。它不能单独使用，但必须由类实现才能使用。
