Assert.AreEqual () exception in VS2010

Question

I am new to unit testing and am using VS2010 to develop and run my tests. I have a simple test shown below that simply compares 2 System.Data.DataTableReader objects. I know that they are equal, because they are both created using the same types of objects, the same input file, and I confirmed that the objects "look" the same.

I understand that I can deal with several problems: one of them is the correct use of Assert.AreEqual or even the correct way to test this script, and the other is the main problem that I am dealing with, so this test does not run with this exception:

Failed 00:00:00.1000660 0 Assert.AreEqual failed. 
Expected:<System.Data.DataTableReader>. Actual:<System.Data.DataTableReader>. 

Below is the unit test code:

public void EntriesTest()
{
    AuditLog target = new AuditLog(); 

    target.Init();

    DataSet ds = new DataSet();
    ds.ReadXml(TestContext.DataRow["AuditLogPath"].ToString());
    DataTableReader  expected = ds.Tables[0].CreateDataReader();
    DataTableReader actual = target.Entries.Tables[0].CreateDataReader();
    Assert.AreEqual<DataTableReader>(expected, actual);
}

Any help would be greatly appreciated!
