字典<string,long>没有被序列化</string,long>

Question

我正在尝试序列化一个简单的 class：

public class Offer_RPC
{
    /// <summary>
    /// this dictionary contains your requested additions ans substractions, in mojos.<br/>
    /// if you wan to offer an nft for example, use the launcher id such as <br/>
    /// "1": 1000000000000 (offer for 1 xch) <br/>
    /// "cc4138f8debe4fbedf26ccae0f965be19c67a49d525f1416c0749c3c865dxxx", -1 <br/>
    /// </summary>
    public Dictionary<string, long> offer = new Dictionary<string, long>();
    public override string ToString()
    {
        JsonSerializerOptions options = new JsonSerializerOptions();
        options.WriteIndented = false;
        options.DefaultIgnoreCondition = System.Text.Json.Serialization.JsonIgnoreCondition.WhenWritingNull;
        string jsonString = JsonSerializer.Serialize(this, options: options);
        return jsonString;
    }
}

调用.ToString() 时，结果 json 为{}

这是我的测试方法：

[Fact]
public void TestOffer()
{
    Offer_RPC test = new Offer_RPC();
    test.offer.Add("1", 1);
    test.offer.Add("2", -1);
    string json = test.ToString();
}

Answer 1

只需通过添加 getter 来修复 class offer 属性

public Dictionary<string, long> offer { get; } = new Dictionary<string, long>();

Answer 2

offer是一个字段，默认情况下字段不会被 System.Text.Json 序列化程序序列化。

你可以：

1. offer房产：
   public Dictionary<string, long> Offer { get; } = new...
2. 包括字段：

    var options = new JsonSerializerOptions { IncludeFields = true, }; var json = JsonSerializer.Serialize(o, options);

Answer 3

问题是要约不是公共财产。 class 应如下所示：

public class Offer_RPC
{
    public Offer_RPC()
    {
        offer = new Dictionary<string, long>();
    }
    /// <summary>
    /// this dictionary contains your requested additions ans substractions, in mojos.<br/>
    /// if you wan to offer an nft for example, use the launcher id such as <br/>
    /// "1": 1000000000000 (offer for 1 xch) <br/>
    /// "cc4138f8debe4fbedf26ccae0f965be19c67a49d525f1416c0749c3c865dxxx", -1 <br/>
    /// </summary>
    public Dictionary<string, long> offer { get; set; }
    public override string ToString()
    {
        JsonSerializerOptions options = new JsonSerializerOptions();
        options.WriteIndented = false;
        options.DefaultIgnoreCondition = System.Text.Json.Serialization.JsonIgnoreCondition.WhenWritingNull;
        string jsonString = JsonSerializer.Serialize(this, options: options);
        return jsonString;
    }
}
