How to get the TestCategory name from TestContext in vb.net

Question

I have a test method with TestCategory attribute as shown below.

<TestMethod()> <TestCategory("myCategory")>
Public Sub TestString()
   Dim a as String="a"
   Dim b as String="b"
   Assert.AreEqual(a,b)
End Sub

can we get the test category name (myCategory) using TestContext in AssemblyInitialize method?

Thanks in advance..
