私は郵便配達を経てこれをテストするとき、それは次の例外がスローされます。
An unhandled exception of type 'System.StackOverflowException' occurred in EntityFramework.dll
私はそれについて検索しましたが、私は私のクエリは正常に動作して選択バレスをスキップしたときに私の場合は異なっています。何故かはわからない。スキップせずに例外をスローします。
私は自分自身で答えを見つける闘争の多くの後..
申し訳ありませんが、このクエリは非常識です。この一歩をさらに進める前に、データモデルを正規化する必要があります。その後、UIのさまざまな部分を別々のステップで作成します。なぜそれはすべて1つの維持できないモノリスでですか？ –
それとは別に、 'StackOverflowException'はコードを実行することができなくても見つけられません。しかし、私はそれが生成しようとしているSQLコードの量でLINQ-to-SQLのチョークを確信しています。 –
@Gert Arnoldこれがクライアントの要件である場合はどうなりますか？私はこれが狂っていることを知っていますが、どうすればそれを行うことができますか？ – user3253756
