获取文档时出现无效操作异常mongodb c#

Question

当我尝试获取刚插入的文档时，我的 Rider IDE 中止了单元测试。我怀疑它与字符串 ID 到 ObjectId 的序列化有关。插入或替换文档没有问题，但它只是在使用 Find() 操作时中止。 这是 mongo 上下文：

public class MongoContext : IMongoContext
{
    private IMongoDatabase Database { get; set; }
    public MongoClient MongoClient { get; set; }
    private readonly List<Func<Task>> _commands;
    public IClientSessionHandle Session { get; set; }

    public MongoContext(string connectionString, string database)
    {
        //BsonDefaults.GuidRepresentation = GuidRepresentation.CSharpLegacy;
        _commands = new List<Func<Task>>();

        RegisterConventions();
        
        MongoClient = new MongoClient(connectionString);
        Database = MongoClient.GetDatabase(database);
    }

    private void RegisterConventions()
    {
        var pack = new ConventionPack
    {
        new IgnoreExtraElementsConvention(true),
        new IgnoreIfDefaultConvention(false)
    };
        ConventionRegistry.Register("My Solution Conventions", pack, t => true);
    }

这是基础实体类：

[Serializable]
public class MongoEntity
{
    [BsonId(IdGenerator = typeof(StringObjectIdGenerator))] 
    [BsonRepresentation(BsonType.ObjectId)]
    [BsonIgnoreIfDefault]
    public string Id { get; set; }
    
}

这是继承的类：

[Serializable]
public class HashKmerOrganism:MongoEntity
{
    public HashKmerOrganism() 
    {
        Organisms = new List<string>();
    }
    public HashKmerOrganism(int hash,string kmer):this() 
    { 
        Hash = hash; 
        Kmer = kmer; 
    }
    public HashKmerOrganism(int hash, string kmer, IEnumerable<string> organisms) : this(hash, kmer)
    {
        Organisms = organisms.ToList();
        
    }
    public HashKmerOrganism(int hash, string kmer, string organism) : this(hash, kmer, new[] { organism }) { }
    public int Hash { get; set; }
    public string Kmer { get; set; }
    public IEnumerable<string> Organisms { get; set; }
    public bool IsKmerReversed { get; set; }
    public double TmApprox { get; set; }
    public int OrganismCount { get => Organisms.Count(); set => OrganismCount = value; }

}

这些是使用的存储库方法：

public async Task Upsert(HashKmerOrganism hashKmerOrganism)
        {
            var filterList = new List<FilterDefinition<HashKmerOrganism>>();
            var filterBuilder = Builders<HashKmerOrganism>.Filter;
            filterList.Add(filterBuilder.Eq(x => x.Hash, hashKmerOrganism.Hash));
            filterList.Add(filterBuilder.Eq(x => x.Kmer, hashKmerOrganism.Kmer));
            var res = await DbSet.ReplaceOneAsync(filterBuilder.And(filterList), hashKmerOrganism, new ReplaceOptions { IsUpsert = true });
        }
        public async Task<HashKmerOrganism> GetByKmer(string kmer) => await DbSet.Find(Builders<HashKmerOrganism>.Filter.Eq(x=>x.Kmer,kmer))
            .SingleAsync();

这是刚刚中止的单元测试：

[TestClass()]
public class HashKmerRepositoryTests
{
    IHashKmerRepository HashKmerRepo;
    private IMongoContext Context;
    [TestInitialize()]
    public void Setup()
    {
        var connectionString = "mongodb://localhost:27017";
        var databaseName = "Organism";
        Context= new MongoContext(connectionString, databaseName);
        HashKmerRepo = new HashKmerRepository(Context);
        
        
    }
    [TestMethod()]
    public async Task UpsertTest()
    {
        var document = new HashKmerOrganism(1, "kmerstring1", "org1");
        var kmer = document.Kmer;
        var documentToReplace = new HashKmerOrganism(1, "kmerstring1", new List<string> { "org1", "org2" });            
        await HashKmerRepo.Remove(document);
        await HashKmerRepo.Upsert(document);
        await HashKmerRepo.Upsert(documentToReplace);
        var actualDoc = await HashKmerRepo.GetByKmer(kmer);
        Assert.AreEqual(documentToReplace.Organisms, actualDoc.Organisms);
        
    }

当我运行单元测试时，我没有收到任何错误消息。它只是中止，这些是日志：

    --- EXCEPTION #1/2 [InvalidOperationException]
Message = “Process was not started by this object, so requested information cannot be determined.”
ExceptionPath = Root.InnerException
ClassName = System.InvalidOperationException

”

这是我的调试控制台输出：

Stack overflow.

任何帮助将不胜感激！

Answer 1

问题出在 HashKmerOrganism 对象的设置器中。它导致了一些未被捕获的递归操作：

public int OrganismCount { get => Organisms.Count(); set => OrganismCount = value; }

被替换为

[BsonElement]
public int OrganismCount {get => Organisms.Count();}
