UI对话框的单选按钮组

//(RadioGroupMethod.Names "A" "B" "C")


int n_method_name;
char **method_names;
ProArrayAlloc(0, sizeof(char *), 1, (ProArray *)&method_names);
status=ProUIRadiogroupNamesGet(dialog_name_,"RadioGroupMethod",&n_method_name,&method_names);//获得从单选组中所选择的单选按钮名
//n_methode_name返回3,
//method_names[0] 为"A"
//method_names[1] 为"B"
//method_names[2] 为"C"
问题是，怎样知道当前选中的是那一个“A”，“B","C"

明白了，是我搞错了，晕哦
ProUIRadiogroupSelectednamesGet()
