对于某些背景,这与Passing IEnumerable Variables into .NET from ColdFusion有关。我改变了代码来使用列表,并取得了进展,但在使用.NET和ColdFusion的简单数据类型以外的其他任何东西时,仍然会遇到障碍。所以这是当前的问题。未找到方法使用ColdFusion列表调用.NET方法

首先,我有一个.dll具有以下VideoWallEvent.cs文件:

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; 
     } 
    } 
} 

我也产生了使用现有的问题JNBProxyGUI.exe以下指示代理对象的对象。把那上面的DLL,我已经生成的代理坛子,运行以下ColdFusion代码:

<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:

正如你可以看到从截图,我可以成功添加项目到列表中,我可以得到期望List对象的ActivityCollection对象,但调用Set_Events方法并通过列表会抛出以下错误:

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推送此列表到Set_Events()方法。

我很好奇,想知道你会得到什么,如果你叫

我弄不明白。 –

我想知道DotNetProxy是否错误地设置了Set_Events()增变器。我想知道如果你在施工过程中用一个空的List 初始化Events属性会有什么不同。 –

不管你相信与否,这只是一个装配路径问题。你必须在汇编列表中使用这两个文件,而不只是CoStarUtilities,即:

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