Question

第三方供应商拥有我正在使用的一系列端点，它们具有以下结构：

[
     {
          "Id" : 117,
          "Name" : "Example"
     },

     {
          "Id" : 118,
          "Name" : "Sample"
     },
]

我创建了一个对象结构：

public class RootObject<TType>
{
     public TType[] ApiModels { get; set; }
}

public class Sample
{
     public int Id { get; set; }
     public string Name { get; set; }
}

但是当我去反序列化时，我会这样做：

JsonConvert.DeserializeObject<RootObject<Sample[]>>(...);

我收到错误，无法反序列化当前JSON数组？为什么？如果我做动态运动，我可以遍历一切，那我就认为我做的事很愚蠢。

更新错误：

发生一个或多个错误。（无法反序列化当前JSON 数组（例如[1,2,3]）放入类型，因为该类型需要JSON 对象（例如{“ name”：“ value”}）正确反序列化。要解决这个问题错误，或者将JSON更改为JSON对象（例如{“ name”：“ value”}）或将反序列化类型更改为实现的数组或类型像List这样的集合接口（例如ICollection，IList）可以从JSON数组反序列化。 JsonArrayAttribute也可以是添加到类型以强制其从JSON数组反序列化。路径 ”，第1行，位置1。）

JSON数组对应于C＃中的/* This is a code for NEC Infrared Transmission Protocol Transmitter NEC specifications are ~ Carrier Frequency is 38kHz * Logical '0' – a 562.5µs pulse burst followed by a 562.5µs space, with a total transmit time of 1.125ms * Logical '1' – a 562.5µs pulse burst followed by a 1.6875ms space, with a total transmit time of 2.25ms - a 9ms leading pulse burst (16 times the pulse burst length used for a logical data bit) - a 4.5ms space - the 8-bit address for the receiving device - the 8-bit logical inverse of the address - the 8-bit command - the 8-bit logical inverse of the command - a final 562.5µs pulse burst to signify the end of message transmission. Example, If the code recieved from the data dump from the IRremote library is 0x2FD807F -0x02 is address -0xFD is the inverse address -0x80 is the command -0x7F is the inverse command THIS PROGRAM IS A BLOCKING PROGRAM */ #define IR 3 #define CarrierFreqInterval 11 void setup() { pinMode(IR, OUTPUT); digitalWrite(IR, LOW); } void loop() { // unsigned long start = micros(); transmit(0x02FD807F); // unsigned long ends = micros(); // unsigned long delta = ends - start; // Serial.println(delta); delay(500); } void transmit(uint32_t data) { //Function for transmiting the data uint32_t bitcount = 0x80000000; // 9ms pulse burst for (int i = 0; i < 355; i++) { digitalWrite(IR, HIGH); delayMicroseconds(CarrierFreqInterval); digitalWrite(IR, LOW); delayMicroseconds(CarrierFreqInterval); } // 4.5ms space delayMicroseconds(4500); //8bit address,adress inverse,command,command inverse while ( bitcount != 0b0) { if ((data & bitcount) == bitcount) { pulseHIGH(); } else { pulseLOW(); } bitcount = bitcount >> 1; } //final pulse burst for (int i = 0; i < 21; i++) { digitalWrite(IR, HIGH); delayMicroseconds(CarrierFreqInterval); digitalWrite(IR, LOW); delayMicroseconds(CarrierFreqInterval); } } void pulseHIGH() { // Pulse 38KHz good for a LOGIC '1' for (int i = 0; i < 21; i++) { digitalWrite(IR, HIGH); delayMicroseconds(CarrierFreqInterval); digitalWrite(IR, LOW); delayMicroseconds(CarrierFreqInterval); } delay(1); delayMicroseconds(687.5); } void pulseLOW() { // Pulse 38KHz good for a LOGIC '0' for (int i = 0; i < 21; i++) { digitalWrite(IR, HIGH); delayMicroseconds(CarrierFreqInterval); digitalWrite(IR, LOW); delayMicroseconds(CarrierFreqInterval); } delayMicroseconds(562.5); }，因此，应序列化为List<T>，而不是序列化为RootObject<Sample[]>：

List<Sample>

在此处使用JsonConvert.DeserializeObject<List<Sample>>(...);是错误的，因为：

您的JSON根是一个数组，而不是一个对象
RootObject<Sample[]>将具有RootObject<Sample[]>类型的ApiModels属性，这显然不是您想要的。
