ServiceStack.Text JsonSerializer - SerializeToString失败惠特DateTime.Max

Question

我在使用c＃的Web应用程序上使用ServiceStack.Text JsonSerializer。问题在于，对于特定的功能，我需要将日期值序列化为json，但当值为DateTime.MaxValue时，目前失败。

下面是一些代码示例复制此（它的一个简单的控制台应用程序）：

class Program 
{ 
    static void Main(string[] args) 
    { 
     var jsonResultMin = JsonSerializer.SerializeToString<DateTime>(DateTime.MinValue); 
     var deJsonMin = JsonSerializer.DeserializeFromString<DateTime>(jsonResultMin); 
     Console.WriteLine("jsonResultMin" + jsonResultMin); 
     Console.WriteLine("deJsonMin" + deJsonMin); 

     var jsonResultMax = JsonSerializer.SerializeToString<DateTime>(DateTime.MaxValue); 
     var deJsonMax = JsonSerializer.DeserializeFromString<DateTime>(jsonResultMax); 
     Console.WriteLine("jsonResultMax" + jsonResultMax); 
     Console.WriteLine("deJsonMax" + deJsonMax); 

     Console.ReadLine(); 

    } 
} 

堆栈跟踪为：

我明白，错误是因为与日期的发生这是ServiceStack库在内部执行的时间转换。

此外，我发现如果您从最大值中减去一天（addDays（-1）），库不会失败。

但有没有一种解决方法，使这项工作无需修改日期？

Answer 1

从UNIX时间转换导致的错误，你可以跳过它，如果你设置了DateHandler，如：

JsConfig.DateHandler = DateHandler.ISO8601DateTime 

如果你想检查所有可能的转换检查source code

Answer 2

您可以跳过与UTC日期时间转换：

JsConfig.SkipDateTimeConversion = true;
