【求助】关于SharpDevelop的代码折叠问题

请问SharpDevelop里面给的例子是{ }为标识进行折叠，如何我想换成两个单词来标识怎么做？{和}声明的时候用的是char类型，不能用string的直接赋值

'{'，你声明的就是char类型， "{"，这是字符串
string s = "{";
s = s.Replace("{", "*");

引用 1 楼 bdmh 的回复:

'{'，你声明的就是char类型， "{"，这是字符串 string s = "{"; s = s.Replace("{", "*");

不是我声明的char类型，是例子中声明的，我想改成多于一个字符的单词为标识，比如以Begin为开始，以Close为结束标识可以折叠，请问应该怎么弄啊？
