Assigning Multiple values to "Person and Group" Column Type programatically

Many times we have requirement of adding multiple values to a column of type "Persons and Group" through object model. There's a way to do that very easily.

public void AssignMultipleValues(String strSemicolonSeperatedMulipleUsers)

{

   String[] userName;

   SPUser objSPUser = null;

   SPFieldUserValueCollection userCollection = new SPFieldUserValueCollection();

   if (!string.IsNullOrEmpty(strSemicolonSeperatedMulipleUsers))

  {

   userName = StringToArray(strSemicolonSeperatedMulipleUsers, ";");

   foreach (string strUserName in userName)

   {

      objSPUser = SPContext.Current.Web.EnsureUser(strUserName);

       if (objSPUser != null)

      {

         userCollection.Add(new SPFieldUserValue(SPContext.Current.Web, objSPUser.ID, objSPUser.Name));

       }

    }

  if (userCollection.Count > 0)

  item[field.ColumnName] = userCollection;

  item.Update();

 }

}

public string[] StringToArray(string input, string separator)

{

string[] stringList = input.Split(separator.ToCharArray(), StringSplitOptions.RemoveEmptyEntries);

return stringList;

}

Thanks
