How do I get my adopted child who was in the foster system to trust me?

It can be difficult to forge a relationship with someone who has been so badly hurt by others, but some of the ways you can proceed can include:

-  Ask the person about their past and let them know that you care.
-  Give them unconditional love and support. 
-  Try to build trust by showing that you mean no harm, but will take care of them, and by being transparent with them.
-  Find ways for the person to feel useful and have a voice, even when they aren’t fully aware of why.
-  Watch for signs of abuse or neglect, and avoid contributing to it. 
-  If you’re worried about the well-being of your child, visit a local children’s advocacy center to get more resources.  (Some cities have a center that is safe for minors to visit, but these tend to be a couple hours’ drive away.)

I’d start by telling her you’re not like the other foster families. I’d tell her that you want to have a real connection with her, and that you’re dedicated to fostering that connection.
