无法从MongoDb C#中的BsonType ObjectId反序列化字符串#

Question

我"Cannot deserialize string from BsonType ObjectId"在尝试从C#WebAPI中获取MongoDb的所有记录时遇到错误

我的身份证明

[BsonId]
public string Id { get; set; }

将其更改为

[BsonRepresentation(BsonType.ObjectId)] 
public string Id { get; set; }

它的工作正常

但是,虽然我正在调用post方法,但它给了我不同的错误

"'d05e139c-3a48-4213-bd89-eba0c22c3c6f' is not a valid 24 digit hex string."

怎么能解决这个问题

我的模型是:

public class EstablishmentDetails
{

    [BsonRepresentation(BsonType.ObjectId)] 
    public string Id { get; set; }
    public string EstablishmentName { get; set; }
    public string EstablishmentType { get; set; }
    public string Address { get; set; }
    public string City { get; set; }
    public int StateID { get; set; }
    public Int32 PIN { get; set; }
    public Int64 PhoneNumber { get; set; }
    public string EmailID { get; set; }
    public bool Published { get; set; }
    public string CreatedDate { get; set; }
    public string ModifiedDate { get; set; }
}

我的存储库来自Get方法

public IEnumerable<EstablishmentDetails> GetAllEstablishmentDetails()
    {
        if (Convert.ToInt32(mCollection.Count()) > 0)
        {
            var EstablishmentDetailsCollection = mCollection.FindAllAs(typeof(EstablishmentDetails));

            if (EstablishmentDetailsCollection.Count() > 0)
            {
                foreach (EstablishmentDetails item in EstablishmentDetailsCollection)
                {
                    establishmentDetails.Add(item);
                }
            }
        }
        var results = establishmentDetails.AsQueryable();
        return results;
    }

我的Post方法库

public EstablishmentDetails Add(EstablishmentDetails ed)
    {
        if (string.IsNullOrEmpty(ed.Id))
        {
            ed.Id = Guid.NewGuid().ToString();
        }

        mCollection.Save(ed);
        return ed;
    }

Answer 1

而不是使用

ed.Id = Guid.NewGuid().ToString();

我用了

ed.Id = MongoDB.Bson.ObjectId.GenerateNewId().ToString();

用于生成Id

它的工作正常:)
