How to convert .Net Framework array to native c++ array ?

I have 3 variable :

1. char TVar1[100];
2. array<char,1>^ TVar2;
3. String^ TVar3;
How can I Copy data on TVar2 or TVar3 to TVar1 ?

nevermind after I try to compile it doesn't work. looks like can't mixed between c++ array with c++ managed array.
