求助，关于正则表达式

[飞龙在笑]

string str1 = "intEMV_InitPara_xxx(void){if(ParaInfo.cFlag==0x00){emv_add_aid_item(ParaInfo.cLenAID,ParaInfo.AID,1);}else{emv_add_aid_item(ParaInfo.cLenAID,ParaInfo.AID,0);}}intEMV_InitPara(void){if(ParaInfo.cFlag==0x00){emv_add_aid_item(ParaInfo.cLenAID,ParaInfo.AID,1);}else{emv_add_aid_item(ParaInfo.cLenAID,ParaInfo.AID,0);}}";
string str2 = "intEMV_InitPara(void)";
string str3 = "intEMV_InitPara_xxx(void)";
在str1的字符串中提取出str2函数名或str3函数名的函数体内容，用正则表达式要什么写？

[飞龙在笑]

或者还有什么其他方法提取函数体内容？

[娃都会打酱油了]

你是要按后面的名称来获取str1的的整个函数方法吗？如果是的话，那你查下正则表达式的平衡组，按花括号进行平衡匹配

[飞龙在笑]

对正则不是很懂，能不能详细一点，就是str1字符串是从文件读取的，然后有一个函数名，想找函数名对应的函数体内容

        private string MatchValue(string text,string pattern)
        {
            pattern = pattern.Replace("(", @"\(").Replace(")", @"\)");
            pattern = "(?is)" + pattern;
            pattern += @"\{((?<group>\{)|(?<-group>\})|[^{}]+)*(?(group)(?!))\}";
            return Regex.Match(text, pattern).Value;
        }

            string str1 = "intEMV_InitPara_xxx(void){if(ParaInfo.cFlag==0x00){emv_add_aid_item(ParaInfo.cLenAID,ParaInfo.AID,1);}else{emv_add_aid_item(ParaInfo.cLenAID,ParaInfo.AID,0);}}intEMV_InitPara(void){if(ParaInfo.cFlag==0x00){emv_add_aid_item(ParaInfo.cLenAID,ParaInfo.AID,1);}else{emv_add_aid_item(ParaInfo.cLenAID,ParaInfo.AID,0);}}";
            string str2 = "intEMV_InitPara(void)";
            string str3 = "intEMV_InitPara_xxx(void)";
            Console.WriteLine(MatchValue(str1,str2));
            Console.WriteLine(MatchValue(str1, str3));

输出:
intEMV_InitPara(void){if(ParaInfo.cFlag==0x00){emv_add_aid_item(ParaInfo.cLenAID,ParaInfo.AID,1);}else{emv_add_aid_item(ParaInfo.cLenAID,ParaInfo.AID,0);}}
intEMV_InitPara_xxx(void){if(ParaInfo.cFlag==0x00){emv_add_aid_item(ParaInfo.cLenAID,ParaInfo.AID,1);}else{emv_add_aid_item(ParaInfo.cLenAID,ParaInfo.AID,0);}}
