Question

我试图从字符串列表创建一个反向文档索引的XML，但无法将所有字符串转换为FSharpList＆lt;＆gt;并在某些迭代中获得此异常：

编辑消息：FSharp.Core.dll中出现“System.Exception”类型的第一次机会异常。该程序执行没有问题，但XML是错误的，因为所有单词都不会被访问。

我无法理解为什么它适用于某些字符串而不适用于其他字符串。

我使用此处的代码将列表转换为FSharp：http://lookingsharp.wordpress.com/2011/03/08/converting-an-ilist-to-an-fsharplist/

是因为我在foreach中创建了var fsharpList2吗？

ToFSharpList（）函数将C＃列表转换为F＃列表。

        foreach (string st in doclist)
        {
            list3.Clear();
            split = st.Split(' ');
            foreach (string str in split)
            {
                if (str != null)
                    try
                    {
                        list3.Add(Module2.stem(str.ToLower())); //using stemmer written in F#
                    }
                    catch
                {
                    list3.Add(str.ToLower());
                }
            }


            //foreach(string str in list3)
            //richTextBox1.Text += str;


                var fsharpList2 = list3.ToFSharpList(); //to convert list of stemmed distinct words to FSharpList
                var perdoc_without_stopword = Module2.stopword(fsharpList2);    //Using Stopword to remove stopwords in the list
                foreach (string str in perdoc_without_stopword)
                    all_processes_words.Add(str);

                all_processes_words.Count();


                var list5 = WordFrequencyUtils.CountWordFrequencies(perdoc_without_stopword); //Calculating word frequencies }

编辑调试输出（最后一行不断重复）：
