Data dkey = new Data(), dvalue = new Data();
try {
dkey = Data.New(key, binfmt, KeyType);
dvalue = Data.New(value, binfmt, ValueType);

if (ret == DB_KEYEXIST) { return false; }
CheckError(ret);
return true;
} finally {
dkey.Free();

}
}示例2: Get
public object Get(object key) {
Data dkey = new Data();
Data dvalue = Data.New();
try {
dkey = Data.New(key, binfmt, KeyType);
int ret = funcs.get(dbp, env.Txn, ref dkey, ref dvalue, 0);
