.net - C# string replace does not actually replace the value in the string

Question

(This question already has answers here): question from:https://stackoverflow.com/questions/13277667/c-sharp-string-replace-does-not-actually-replace-the-value-in-the-string

Answer 1

The problem is that strings are immutable. The methods replace, substring, etc. do not change the string itself. They create a new string and replace it. So for the above code to be correct, it should be

path1 = path.Replace("\bin\Debug", "\Resource\People\VisitingFaculty.txt");

Or just

path = path.Replace("\bin\Debug", "\Resource\People\VisitingFaculty.txt");

if another variable is not needed.

This answer is also a reminder that strings are immutable. Any change you make to them will in fact create a new string. So keep that in mind with everything that involves strings, including memory management. As stated in the documentation here.

String objects are immutable: they cannot be changed after they have been created. All of the String methods and C# operators that appear to modify a string actually return the results in a new string object
