未找到方法调用.NET方法与ColdFusion的列表 [英] Method Not Found Calling .NET Method with List from ColdFusion

问题描述

有关的一些背景，这是关系到<一个href="http://stackoverflow.com/questions/16742477/passing-ienumerable-variables-into-net-from-coldfusion">Passing IEnumerable的变量到从ColdFusion的.NET 的。我已经改变了code使用一个列表，而不是，并取得了进展，但仍然在使用什么比使用.NET和ColdFusion的简单数据类型等打路障。因此，这里的当前问题。

For some background, this is related to Passing IEnumerable Variables into .NET from ColdFusion. I've changed the code to use a list instead, and have made progress, but continue to hit roadblocks when using anything other than simple data types with .NET and ColdFusion. So here's the current issue.

首先，我有以下VideoWallEvent.cs文件一个.dll：

First, I have a .dll with the following VideoWallEvent.cs file:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace CoStar.Utilities.VideoWall
{
    public class VideoWallEventActivityCollection
    {
        public string CountryCode { get; set; }
        public DateTime ActivityDate { get; set; }
        public List<VideoWallEvent> Events { get; set; }

    }

    public class VideoWallEvent
    {

        public string ID { get; set; }
        public decimal Latitude { get; set; }
        public decimal Longitude { get; set; }

        public VideoWallEvent(string EventID, decimal EventLatitude, decimal EventLongitude)
        {
            ID = EventID;
            Latitude = EventLatitude;
            Longitude = EventLongitude;
        }
    }
}

我也产生了使用 JNBProxyGUI.exe 下面由现有问题的说明的代理对象的对象。把那上面的DLL，我已经生成的代理罐子，我运行下面的ColdFusion code：

I've also generated a proxy object object using JNBProxyGUI.exe following instructions from the prior question. Give that the above dll, and the proxy jar I've generated, I run the following ColdFusion code:

<cfset UtilitiesProxy = ExpandPath("UtilitiesProxy.jar") />
<cfset CoStarUtilities = ExpandPath("CoStar.Utilities.dll") />
<cfset Paths = ArrayToList([CoStarUtilities, UtilitiesProxy])>

<cfset theEvent = CreateObject(".net", "CoStar.Utilities.VideoWall.VideoWallEvent", Paths) />
<cfset eventList = CreateObject(".net","System.Collections.Generic.List`1", Paths).init(theEvent.getDotNetClass()) />

<cfset eventList.Add(theEvent.Init("1234", javacast("bigdecimal","30.2669444"), javacast("bigdecimal","-97.7427778"))) />
<cfset eventList.Add(theEvent.Init("1235", javacast("bigdecimal","30.2669444"), javacast("bigdecimal","-97.7427778"))) />

<cfset eventCollection = CreateObject(".net", "CoStar.Utilities.VideoWall.VideoWallEventActivityCollection", CoStarUtilities) />
<cfdump var="#eventList.ToArray()#" label="Items in eventList" />
<hr />
<cfdump var="#eventCollection#" label="eventCollection" />
<cfdump var="#eventList#" label="eventList" />

<cfset eventCollection.Set_Events(eventList) />

这给了我下面的输出：

正如你从截图中可以看到，我可以成功地将项目添加到列表中，我能得到一个期望List对象的ActivityCollection对象，但调用 Set_Events 方法并通过列表引发以下错误：

As you can see from the screenshot, I can successfully add items to the list, I can get the ActivityCollection object that expects a List object, but calling the Set_Events method and passing the List throws the following error:

The Set_Events method was not found.

Either there are no methods with the specified method name and argument types 
or the Set_Events method is overloaded with argument types that ColdFusion cannot
decipher reliably. ColdFusion found 0 methods that match the provided arguments. 
If this is a Java object and you verified that the method exists, use the javacast 
function to reduce ambiguity.

The error occurred in C:/inetpub/scribble/VideoWall/index.cfm: line 17
15 :    <cfdump var="#eventList#" label="eventList" />
16 : 
17 :    <cfset eventCollection.Set_Events(eventList) />

所以，我现在需要帮助搞清楚如何正确地推名单到Set_Events（）方法。

So I now need help figuring out how to properly push this List into the Set_Events() method.

（从评论）的

不管你相信与否，这只是一个程序集路径问题。你必须在汇编列表中使用这两个文件，​​而不仅仅是 CoStarUtilities ，即：

Believe it or not it is just an assembly path problem. You have to use both files in the assembly list, not just CoStarUtilities, ie:

 <cfset eventCollection = CreateObject(".net"
                 , "CoStar.Utilities.VideoWall.VideoWallEventActivityCollection"
                 , Paths ) />
