I'm trying to access some variables in my shader, but I think I'm doing this wrong. Say I have a constant buffer that looks like this:

cbuffer perFrame
{
    float foo;
    float bar;
};

I got an ID3D10EffectConstantBuffer reference to it, and I can get a specific index by calling GetMemberByIndex, but how can I figure out how many members perFrame has so that I can get each member without going out of bounds?
