EF Core 包含 Concat 字符串

Question

in my .net core service I have a list as follows:

List<string> list = new(){
    110234,
    231798,
    445978
}

The database table has the following columns: int1(2) , int(3) , int3(1) . Now I want to query all records where the concat string maches. But with following example I get a LINQ/Ef-Core exception that this expression can't be translated:

 myentities = myentities
    .Where(e => list.Contains($"{e.int1.ToString("00")}{e.int2.ToString("000")}{e.int3.ToString("0")}"))
    .ToList();

Does anyone has an idea how I can handle that?

The solution suggested from @Svyatoslav Danyliv solved my issue:

Use this solution . I hope it is straightforward how to apply filtering in your case. query = query.FilterByItems(list, (e, x) => e.Field1 == x.Id1 && e.Field2 == x.Id2, true)
