我将以下json数据作为字符串
string data = "{\"STARTTIME\":\"12:00\",\"ENGINNEERSIGNATURE\":\"Engineer Signature .jpg\",\"OVERNIGHTS\":\"1\",\"SIGNOUT\":\"Yes\"}"
var dataOut = JsonConvert.DeserializeObject<Dictionary<string, string>>(data);
我需要将其转换为字典对象,但在尝试
时出现以下错误Newtonsoft.Json.JsonSerializationException: Error converting value "{"STARTTIME":"12:00","ENGINNEERSIGNATURE":"Engineer Signature .jpg","OVERNIGHTS":"1","SIGNOUT":"Yes"}" to type 'System.Collections.Generic.Dictionary`2[System.String,System.String]'. Path '', line 1, position 119. ---> System.ArgumentException: Could not cast or convert from System.String to System.Collections.Generic.Dictionary`2[System.String,System.String].

我哪里出错
答案 0 :(得分:0)
尝试使用Dictionary<string,object>
,这将允许JSON的值为任何对象类型。 Dictionary<string,string>
仅在JSON对象的所有值都是string类型时才有效。但是如果有任何其他值,比如数组或嵌套的JSON对象,它将失败。

无法确定那里有什么问题,但是你能告诉我这个小程序在控制台的前两行打印,在你的示例代码在同一台机器上运行,我可以发现两个可能的问题Newtonsoft版本或者你本地培养

using System.Collections.Generic;
using System.Diagnostics;
