声明时：

 

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

 

使用时：（line 7，line20）

 

 

代码

1 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

 

 

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

 

会报错：
