因此,本题答案为A。首先定义两个字符串变量s和s1,分别用于表示主字符串和待判断子串。接着定义一个方法CheckSubstring,使用Contains方法来判断s1是否为s的子串。在主函数中调用CheckSubstring方法,并输出结果。使用IndexOf方法可以获取一个字符串在另一个字符串中第一次出现的位置。由此,可以得出本题答案。
FIND_IN_SET(str,strlist) 说明 返回字符串集合strlist中指定字符串str的位置,从1开始。如果str不存在于strlist,则返回0。如果str或strlist为NULL,则返回NULL。 str字符串中不能包含逗号(,)。 示例 obclient>SELECTFIND_IN_SET('b','a,b,c,d');+---+|FIND_IN_SET('b','a,b,c,d')|+---+|...
