c# - How do I translate a spherical coordinate to a Cartesian one?

Could someone point me in the right direction as to how this might be achieved? 3D math / geometry often throws me.

I'm looking for something like this (ideally in C#):

public Vector3 getCartesianFor(float elevation, float asimuth, float polar)
{
   return ????;
}

public static void SphericalToCartesian(float radius, float polar, float elevation, out Vector3 outCart){
    float a = radius * Mathf.Cos(elevation);
    outCart.x = a * Mathf.Cos(polar);
    outCart.y = radius * Mathf.Sin(elevation);
    outCart.z = a * Mathf.Sin(polar);
}



public static void CartesianToSpherical(Vector3 cartCoords, out float outRadius, out float outPolar, out float outElevation){
    if (cartCoords.x == 0)
        cartCoords.x = Mathf.Epsilon;
    outRadius = Mathf.Sqrt((cartCoords.x * cartCoords.x)
                    + (cartCoords.y * cartCoords.y)
                    + (cartCoords.z * cartCoords.z));
    outPolar = Mathf.Atan(cartCoords.z / cartCoords.x);
    if (cartCoords.x < 0)
        outPolar += Mathf.PI;
    outElevation = Mathf.Asin(cartCoords.y / outRadius);

}
