How to replace all the tag values in C#

Consider I have an XML as

XML

need to replace FName to FirstName, LName to LastName and DOB to DateOfBirth in C#

There are other elements in the XML as well which needs to be untouched and remain as is.

The fact that you have said that you have tried using Replace suggests that you are just treating this XML as a string.

There are many libraries for handling XML files - use one of those and amending the value of any tag becomes trivial.

Some suggestions to get you started, from CodeProject
Working with XML[^]
Using XML in C# in the simplest way[^]
Reading and Writing XML in C#/VB.Net[^]

And from elsewhere
XmlDocument Class (System.Xml) | Microsoft Docs[^]
Introduction to XML with C# - The complete C# tutorial[^]
C# XmlReader - reading XML in C# with XmlReader[^]

Choose the library that suits you and the style of writing that suits you. Follow the instructions and ... there you go!

Solution 2

This is simple using LINQ to XML:

C#

XDocument doc = XDocument.Load("...path to your XML file...");

doc.Root.Element("FName").Name = "FirstName";
doc.Root.Element("LName").Name = "LastName";
doc.Root.Element("DOB").Name = "DateOfBirth";
