How to Overwrite existing Taxonomy term and nested terms programmatically

Question

Hi,
I have created Taxonomy term (Term A) and nested terms(Subterm1, Subterm2, SubTerm3, etc) programmatically.
Now I want to update sub terms(SubTerm1, SubTerm3, SubTerm4, SubTerm5, etc) programmatically.There are more than 100 sub terms, so I want to update sub terms programmatically.
Here is my code:
var site = properties.Feature.Parent as SPSite;
var taxonomySession = new TaxonomySession(site);
if (taxonomySession.TermStores.Count != 0)
var termStore = taxonomySession.TermStores["Managed Metadata Service"];
var group = termStore.Groups["Group A"];
var termSet = group.TermSets["TermSet A"];
var TermA = termSet.CreateTerm("Term A", CultureInfo.CurrentCulture.LCID);
TermA .CreateTerm("SubTerm1",CultureInfo.CurrentCulture.LCID);TermA.CreateTerm("SubTerm2", CultureInfo.CurrentCulture.LCID);
TermA.CreateTerm("SubTerm3", CultureInfo.CurrentCulture.LCID);
Can anybody let me know how to update the nested terms?
Any help would be appreciated.
Thank you,
AA.

Hi,
The following code for your reference:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Taxonomy;
namespace ConsoleApplication
class Program
static void Main(string[] args)
using (SPSite site = new SPSite("http://sp:5000/"))
TaxonomySession taxonomySession = new TaxonomySession(site);
TermStore termStore=taxonomySession.TermStores["Managed Metadata Service"];
var group=termStore.Groups["Group A"];
var termSet=group.TermSets["TermSet A"];
var topTerm = termSet.Terms["Term A"];
var subTerms = topTerm.Terms;
foreach (Term term in subTerms)
if (term.Name.Equals("SubTerm1"))
term.Name = "SubTerm-1";
if (term.Name.Equals("SubTerm2"))
term.Name = "SubTerm-2";
if (term.Name.Equals("SubTerm3"))
term.Name = "SubTerm-3";
termStore.CommitAll();
