在C＃中反序列化json的问题 [英] Issues deserializing json in C#
本文介绍了在C＃中反序列化json的问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我提前道歉，因为这可能是一个简单的解决方案，对于所有阅读它的人来说都会过于烦人。但是，提前感谢任何和所有帮助！我没有多年编码，但最近的事件要求我再次回来。除了VB6之外，我从来没有编写任何代码，所以这对我来说都是一个学习过程。我正在尝试使用newtonsoft.json反序列化从White Pages Pro api返回的json字符串。一切都运作良好，并且完美无序地反序列化直到我的商业。过去的一切都是我遇到问题的地方。我遇到的错误如下：
I appologize in advance as this is probably an easy fix, and going to be overly annoying for all who read it. However thanks in advance for ANY and ALL help given! I haven't coded in years, however recent events require me to pick back up again. I've never coded in anything except VB6, so this is all a learning process to me. I'm trying to use newtonsoft.json to deserialize a json string returned from White Pages Pro api. Everything worked perfectly and deserialized flawlessly UNTIL i got to is_commercial. Everything past there is where I run into issues with. The errors I'm encountering are as follows:
WhitePagesTool.jsonPersonComplex' does not contain a definition for 'Name' and no extension method 'Name' accepting a first argument of type 'WhitePagesTool.jsonPersonComplex' could be found (are you missing a using directive or an assembly reference?)
同样会出现以下所有错误：
firstname，middlename，lastname，age_range，gender，street_line_1，street_line_2，city，postal_code，state_code，country_code，纬度，经度，准确度，和associated_people
这是我将要使用的典型Json字符串（由于显而易见的原因而更改了信息）：
Also throws the same error for all the following:
firstname, middlename, lastname, age_range, gender, street_line_1, street_line_2, city, postal_code, state_code, country_code, latitude, longitude, accuracy, and associated_people
This is the typical Json string I'll be working with (changed info for obvious reasons):

推荐答案
你的代码是：
debugOutput("Name: " + jPerson.Name);但是你的财产定义是：
public string name { get; set; }这是 name 而不是 Name ：C＃标识符区分大小写。
So that's name rather than Name: C# identifiers are case-sensitive.

The code generated maps the JSON property names to CamelCase C# properties. This should help reduce the confusion in your code.
UPDATE: Added support for nullable types.
