The indexOf method is used to get the integer value of a particular index of String type object, based on criteria specified in the parameters of the IndexOf method. A common scenario can be when a system admin wants to find the index of the '@' character of the email Id of a client and then wants to get the remaining substring.

I need to get the starting position of new line when looping through a StringBuffer. Say I have the following document in a stringbuffer "This is a test Test Testing Testing" New lines exist after " The indexOf(String target) method searches left-to-right inside the given string for a "target" string. The indexOf() method returns the index number where the target string is first found or -1 if the target is not found. Like equals(), the indexOf() method is case-sensitive, so uppercase and lowercase chars are considered to be different. Hi, I'm having a bit fo problem with this still. My original program is used to output the length (in characters, words and lines) of a file, and that works fine. I'm now trying to add code that will output how many occurrences of the second argument exist and on how many seperate lines (this second bit coming later). IndexOf(String, Int32, StringComparison) Reports the zero-based index of the first occurrence of the specified string in the current String object. Parameters specify the starting search position in the current string and the type of search to use for the specified string. IndexOf(Char, Int32, Int32) The indexOf() method returns the index within the calling String object of the first occurrence of the specified value, starting the search at fromIndex. Returns -1 if the value is not found. The source for this interactive example is stored in a GitHub repository. In C#, IndexOf() method is a string method. This method is used to find the zero based index of the first occurrence of a specified character or string within current instance of the string. The method returns -1 if the character or string is not found. This method can be overloaded by passing different parameters to it.
