System.Text.Json

Question

我正在使用 System.Text.Json 但由于某种原因它最近坏了并且不想反序列化它。这是我得到的异常：

{"The JSON value could not be converted to QSGEngine.Web.Exchanges.Exchanges.Binance.AccountTradeResponse. Path: $ | LineNumber: 0 | BytePositionInLine: 1."}

我也想知道如何进行正确的错误处理，因为它曾经抛出 InvalidOperationException（没有当前的 try catch 块）而我几乎没有发现实际的反序列化导致它。

try
{
    var asd = JsonSerializer.Deserialize<T>(json, new JsonSerializerOptions
    {
        PropertyNameCaseInsensitive = true,
        NumberHandling = JsonNumberHandling.AllowReadingFromString
    });
}
catch (Exception ex)
{
    Console.WriteLine(ex);
    throw;
}

JSON 数据是此代码块中的数组。所以你正在尝试反序列化到对象。如果你有机会反序列化像 List<AccountTradeResponse> 或 IEnumrable<AccountTradeResponse>

这样的函数类型

System.Text.Json - 无法反序列化

System.Text.Json - Unable to deserialize

.net

c#

.net-core
