LINQ expression node type 'ArrayIndex' is not supported in LINQ to Entities.

I am stuck on a LINQ issue. I am getting the following error:

The LINQ expression node type 'ArrayIndex' is not supported in LINQ to Entities.

This is my where it is failing:

FeeAuth_STRMDetail.STRM = STRMS[i];

bool CheckIDExist = db.FeeAuth_STRM_Detail.Any(fa => fa.FeeAuthID == feeauth.ID && fa.STRM == STRMS[i]);

Any ideas of how to get past this?
