Check UserID exists in Active Directory

Check UserID exists in Active Directory

Hi every one today we are going to see whether a user exist in the active directory or not using C#.    
  1.  Please add the System.DirectoryServices.AccountManagement namespace and assembly to your code.
[csharp] public string DoesUserExist(string userName) { using (var domainContext = new PrincipalContext(ContextType.Domain, "spl")) { using (var foundUser = UserPrincipal.FindByIdentity(domainContext, IdentityType.SamAccountName, userName)) { if (foundUser != null) return foundUser.Name; else return "User Does not exist "; } } } [/csharp]
