声明时：

__gc struct WordElem{
2     String* pattern;
3     String* replacement;
4     WordElem* next;
5 };

使用时：（line 7，line20）

WordElem* getReplaceWordList(constchar* subs_filename){
 2 
 3     String *subs_file =new String(subs_filename);
 4     StreamReader *subs_reader =new StreamReader(subs_file);
 5 
 6     WordElem *head, *tail, *temp;
 7     head =new WordElem;
 8     head->pattern ="";
 9     head->replacement ="";
10     head->next =0;
11 
12     tail = head;
13 
14     String *pattern, *replacement;
15 while (subs_reader->Peek() >=0) {
16             pattern = subs_reader->ReadLine();
17             replacement = subs_reader->ReadLine();
18             subs_reader->ReadLine();
19             
20             temp =new WordElem;
21             temp->pattern = pattern;
22             temp->replacement = replacement;
23             temp->next =0;
24 
25             tail->next = temp;
26             tail = temp;
27         }
28 
29     subs_reader->Close();
30 return head;
31 }

之前使用

typedef struct Word{
2     String* pattern;
3     String* replacement;
4 struct Word *next;
5 } WordElem;

会报错：
