How to get list of selected test case in MSTest with C#

Question

I'm trying to retrieve a list of the selected test to run in ClassInitialize. Can you help with that?

[ClassInitialize]
public void classInitialize()
{
    String name=TestContext.CurrentContext.Test.MethodName;
}

Using the above code I'm able to get only the current running test cases.

[ClassInitialize]
public void ClassInitialize()
{
    //Need to get the list of the selected test to run.
}

Actual: I'm unable to retrieve selected tests.

Expected: Should list of the list of test to run.
