我有一个包含内容的字符串变量:

I have a string variable with content:

varMessage = "hi/thsid/sdfhsjdf/dfjsd/sdjfsdn\n" "/my/name/is/balaji.so\n" "call::myFunction(int const&)\n" "void::secondFunction(char const&)\n" . . . "this/is/last/line/liobrary.so"

在字符串中我必须找到一个子字符串:

In the string I have to find a sub-string:

"hi/thsid/sdfhsjdf/dfjsd/sdjfsdn\n" "/my/name/is/balaji.so\n" "call::myFunction(int const&)\n"

我怎样才能找到它?我需要确定子字符串是否存在.

How can I find it? I need to determine whether the sub-string is present or not.

推荐答案

您可以使用 include? 方法:

You can use the include? method:

my_string = "abcdefg" if my_string.include? "cde" puts "String includes 'cde'" end
