對於某些背景,這與Passing IEnumerable Variables into .NET from ColdFusion有關。我改變了代碼來使用列表,並取得了進展,但在使用.NET和ColdFusion的簡單數據類型以外的其他任何東西時,仍然會遇到障礙。所以這是當前的問題。未找到方法使用ColdFusion列表調用.NET方法

首先,我有一個.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; 
     } 
    } 
} 

我也產生了使用現有的問題JNBProxyGUI.exe以下指示代理對象的對象。把那上面的DLL,我已經生成的代理罈子,運行以下ColdFusion代碼:

<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) /> 

這給了我下面的輸出:

正如你可以看到從截圖,我可以成功添加項目到列表中,我可以得到期望List對象的ActivityCollection對象,但調用Set_Events方法並通過列表會拋出以下錯誤:

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) /> 

所以我現在需要幫助搞清楚如何正確推送此列表到Set_Events()方法。

我很好奇,想知道你會得到什麼,如果你叫

+0

我弄不明白。 –

我想知道DotNetProxy是否錯誤地設置了Set_Events()增變器。我想知道如果你在施工過程中用一個空的List 初始化Events屬性會有什麼不同。 –

(從評論)

不管你相信與否,這只是一個裝配路徑問題。你必須在彙編列表中使用這兩個文件,而不只是CoStarUtilities,即:

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