Deleting User From Active Directory c#.net

Introduction

I have written an application for deleting accounts from the Active Directory wrapper.

public static string DelUserInAD(string sGroupName, string strDomain, string strName)
{
bool done = false;
string result = string.Empty;
try
{
PrincipalContext oPrincipalContext = GetPrincipalContext();
string sUserName = strDomain + "\\" + strName;
UserPrincipal oUserPrincipal = UserPrincipal.FindByIdentity(oPrincipalContext, sUserName);
GroupPrincipal oGroupPrincipal = GetGroup(sGroupName);
if (oUserPrincipal != null && oGroupPrincipal != null)
{
if (IsUserGroupMember(sUserName, sGroupName))
{
//oGroupPrincipal.Members.Add(oUserPrincipal);
//oGroupPrincipal.Save();
oGroupPrincipal.Members.Remove(oUserPrincipal);
oGroupPrincipal.Save();
done = !(oUserPrincipal.IsMemberOf(oGroupPrincipal));
}
else
{
result = sUserName + " already exists. Exiting!!";
}
}
}
catch
{
}
return result;
}
