Can't I make BlendShape animation into animationClip?

Can't I make BlendShape animation into animationClip?
Is there only a way to use SetBlendShapeWeight?

I am trying to create a BlendShape AnimationClip using AnimationClip.SetCurve.
But I have no information. I want to know what variables should go in ...



<Below is a part of the code>

GameObject o = GameObject.Find(mBlendShape.name);
SkinnedMeshRenderer so = o.GetComponent<SkinnedMeshRenderer>();
Mesh mo = so.sharedMesh;
string primitiveObjPath = o.name + "/Primitive" + 1; // will be loaded only Primitive1
mAnimationClip.SetCurve(primitiveObjPath, typeof(SkinnedMeshRenderer), mo.GetBlendShapeName(j), curve);
