在msxsl中使用程序集和名称空间的问题 [英] Issue using assemblies and namespaces in msxsl

问题描述

我有一个XSL转换，该转换使用msxsl在C#中添加扩展方法.我为msxsl设置了以下设置:

I have an XSL transform that is using msxsl to add extension methods in C#. I have the following setup for msxsl:

<msxsl:script language="C#" implements-prefix="cs">
    <msxsl:assembly name="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />
    <msxsl:assembly name="System.Xml.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" />
    <msxsl:using namespace="System.Collections.Generic" />
    <msxsl:using namespace="System.Linq" />
    <msxsl:using namespace="System.Xml.Linq" />

然后我有了一个c#函数作为扩展方法:

I then have a c# function as an extension method:

public int returnUniqueCount(string theCodeCollection) {
      // calculate and return the total number of distinct codes
      if (theCodeCollection.Length > 0) {
        string[] myObject = theCodeCollection.Split('|');
        string[] uniqueCollection = myObject.Distinct().ToArray();
        return uniqueCollection.Length;

      } else {
        return 0;

      }

    }

从本质上讲，它只需要一个带标记的字符串，将其拆分，然后对结果集进行计数(不包括重复项).

Essentially that just takes a tokenized string, splits it, and counts the result set excluding duplicates.

该转换在服务器上运行良好，但是当我尝试对其进行概要分析时，出现以下错误:

The transform runs fine on the server, but when I try to profile it, I get the following error:

'System.Array' does not contain a definition for 'Distinct'

整个早晨，我一直在ash头，但我只是没有看到它.有什么想法吗?

I've been bashing my head against this all morning and I'm just not seeing it. Any ideas?

谢谢.

推荐答案

我遇到了同样的问题，显然具有模板返回值的模板方法无法用于脚本编写，只有具有明显返回值的方法(如ContainsKey()和Count)才可用.可用.

I have the same problem, apparently template methods that has a template return are not available for scripting, only methods that has a distinct return like ContainsKey() and Count are availble.
