string.Replace() Function

Question

I am trying to replace a sub-string in the errorString. i am using this code,which is not making any changes to errorString. am i following a wrong method?

 string errorstring = "<p>&nbsp;&nbsp;&nbsp;Name:{StudentName}</p>";
 errorstring.Replace("{StudentName}", "MyName");

i want to replace {StudentName} in errorString with "MyName"

Strings are immutable and you're just creating new string instance, use `errorstring = errorstring.Replace("{StudentName}", "MyName");` instead. — Tetsuya Yamamoto, Jul 14 '17 at 04:47

Declare a new instance of that string:

string errorstring = "<p>&nbsp;&nbsp;&nbsp;Name:{StudentName}</p>";
errorstring = errorstring.Replace("{StudentName}", "MyName");

That should work if you don't use StringBuilder.
