Collection Class NOT found in C#, but found in vb.net !! Why?

Question

Recently, I am coding a c# module (previously was written in vb.net), I found that "Collection Class" did NOT exist in c# but it can be found in vb.net !!

======================================
My Computer: .NetFramework 1.1 & VS.NET 2003
======================================

And therefore I am forcing myself to use the following methods to solve the "missing class" in c#

Step 1. Under the Solution Explorer, Add Reference "Microsoft.VisualBasic"
Step 2. Under the *.cs file, Type using Microsoft.VisualBasic;
Step 3: Under the *.cs file, Type Collection m_result = new Collection;

In fact, I can NATIVELY use Collection in vb.net

Dim m_results As New Collection

This is the way I can use Collection in c#.  May I ask if any experts here can give me an answer what is the "suitable" way to have Collection?  or Am I correct?

Here below is one of the functions (written in VB.NET) I use Collection and "grap" the data in the DAL Layer and use it for UI Layer:

----------------------------------------------------
Public Function GetBrands() As Collection

Dim m_da As New MySqlDataAdapter

Dim m_ds As New DataSet

Dim m_data As m_BrandData

Dim m_results As New Collection

Dim m_dataRow As DataRow

Dim m_SQL As String

m_SQL = "Select * From tb_Brand order by brandName"

m_da.SelectCommand = New MySqlCommand(m_SQL, m_conn)

m_da.Fill(m_ds, "table1")

For Each m_dataRow In m_ds.Tables("table1").Rows

m_data = New m_BrandData

With m_data

.brandCode = CStr(m_dataRow.Item("brandCode"))

.brandName = CStr(m_dataRow.Item("brandName"))

End With

m_results.Add(m_data)

m_data = Nothing

Next

GetBrands = m_results

End Function
----------------------------------------------------

How may I do the same thing in C#?  Do I have to use Microsoft.VisualBasic reference (that's NOT native to me"?

Please advice
