我有一个从数据库填充的列表，我想将此列表绑定到数据网格，任何



的帮助将不胜感激。以下是我的代码：

i am having a list populated from a database, i want to bind this list to a datagrid, any

assistance will be appreciated. below is my code:

 public List<string> listUserNameDuplicate = new List<string>();
 public List<string> listUserName = new List<string>();
while (reader.Read())
                {
                    
                    listUserName.Add(reader["FirstName"].ToString().ToUpper());
                    listUserNameDuplicate.Add(reader["LastName"].ToString().ToUpper());
                    listUserNameDuplicate.Add(reader["FirstName"].ToString().ToUpper());
                    listUserNameDuplicate.Add(reader["MiddleName"].ToString().ToUpper());
                    listUserNameDuplicate.Add(reader["ClassName"].ToString().ToUpper());

i以这种方式呼叫列表：

下面的相应记录。





我还想检查listUserName是否包含多个用户名。

corresponding records below.


And i also want to check whether the listUserName contains more than one username.
