Question

How can we divide the substring from the string

Like I have string

String mainString="///Trade Time///Trade Number///Amount Rs.///";

Now I have other string

String subString="Amount"

Then I want to extract the substring Amount Rs. with the help of second string named subString not by any other method But it should be extracted through two parameters like first is I have index no of Amount string and second is until the next string ///.

Answer 1

First get the index of the substring:

int startIndex = mainString.IndexOf(subString);

Then get the index of the following slashes:

int endIndex = mainString.IndexOf("///", startIndex);

Then you can get the substring that you want:

string amountString = mainString.Substring(startIndex, endIndex - startIndex);
