Bagaimana untuk Mendapatkan ID Rekod yang Baru Dimasukkan dalam SQL Server menggunakan C#?

<code class="language-csharp">public class MemberBasicData
{
    public int Id { get; set; }
    public string Mem_NA { get; set; }
    public string Mem_Occ { get; set; }     
}

public int CreateNewMember(string Mem_NA, string Mem_Occ )
{
    using (SqlConnection con=new SqlConnection(Config.ConnectionString))
    {
        using(SqlCommand cmd=new SqlCommand("INSERT INTO Mem_Basic(Mem_Na,Mem_Occ) VALUES(@na,@occ)",con))
        {
            cmd.Parameters.AddWithValue("@na", Mem_NA);
            cmd.Parameters.AddWithValue("@occ", Mem_Occ);
            con.Open();

            int modified = cmd.ExecuteNonQuery();

            if (con.State == System.Data.ConnectionState.Open) con.Close();
                return modified;
        }
    }
}</code>

<code class="language-csharp">using(SqlCommand cmd=new SqlCommand("INSERT INTO Mem_Basic(Mem_Na,Mem_Occ) OUTPUT INSERTED.ID VALUES(@na,@occ)",con))
{
    cmd.Parameters.AddWithValue("@na", Mem_NA);
    cmd.Parameters.AddWithValue("@occ", Mem_Occ);
    con.Open();

    int newId = (int)cmd.ExecuteScalar();

    if (con.State == System.Data.ConnectionState.Open) 
        con.Close();

    return newId;
}</code>

<code class="language-csharp">using(SqlCommand cmd=new SqlCommand("INSERT INTO Mem_Basic(Mem_Na,Mem_Occ)  VALUES(@na,@occ);SELECT SCOPE_IDENTITY();",con))
{
    cmd.Parameters.AddWithValue("@na", Mem_NA);
    cmd.Parameters.AddWithValue("@occ", Mem_Occ);
    con.Open();

    int newId = Convert.ToInt32(cmd.ExecuteScalar());

    if (con.State == System.Data.ConnectionState.Open) con.Close();
        return newId;
}</code>
