如何在C＃中将数据集转换为用户对象？

Question

// GetUserByUsername
public DataSet GetUserByUsername(string Username)
{
    User _user = null;
    using (SqlCommand cmd = new SqlCommand(DBHelper.UserMethod("GetUsername"),con))
    {
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@username", Username);
        SqlDataAdapter da = new SqlDataAdapter();
        DataSet ds = new DataSet();
        da.Fill(ds);                
    }
    return ds;
}

In my above method return type is DataSet , here my dout is if I change the DataType to User then how to Convert that DataSet ds to User let me show you.

For example:

// GetUserByUsername
public User GetUserByUsername(string Username)
{
    User _user = null;
    using (SqlCommand cmd = new SqlCommand(DBHelper.UserMethod("GetUsername"),con))
    {
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@username", Username);
        SqlDataAdapter da = new SqlDataAdapter();
        DataSet ds = new DataSet();
        da.Fill(ds);                
    }
    return (User)ds;
}

Can I use in this way or is their any other way can I use instead of DataSet, DataTable ?

If you don't want to build the User obj by parsing the results yourself go for the automapper lib OR there is a such a thing as strongly type datasets (IE define a set AS User). Its been a long time since I've done that but this will get you started https://msdn.microsoft.com/en-us/library/esbykkzb(v=vs.110).aspx
