C＃：JSON DeserializeObject給人異常

Question

我有一個JSON字符串像如下所示的我從一個Web服務得到：

"[[\"XYZ40E\",\"D  XYZ-12572\",\"XYZ, XYZ HARDWARE END ITEM, XYZ40 (REV D) IXYZ SE KPD\"],[\"5.001.0.045\",\"M  XYZ-14280\",\"PROGRAMMING AND CONFIGURING IXYZ SE XYZ\"],[\"222TTEK0000\",\"A  XYZ-14631\",\"XYZ, XYZ40, MULTIXYZ, SE REV D, XYZ, STD XYZ, STD, XYZ, PIG, BLK, STD 1 SECURITY, LED RED, FLASH GRN, BZR ON, IPM OFF, KPF-4-BIT, 32 BIT\"],[\"4505-104-10\",\"E  XYZ-10728\",\"LBL, PROD, MULTICLASS SE XYZ40, REV D XYZ\"],[\"4505-105-10\",\"D  XYZ-10850\",\"LBL, XYZ SIDE SHPNG, MULTIXYZ SE XYZ40, REV D XYZ\"],[\"XYZ-GRPC-003N\",\"B  XYZ-11880\",\"CFG PFL, LF STD, HF XYZ\\/SIO\\/XYZ, XYZG, LED RED, FLXYZ GRN, BZR ON, CSN 34-BIT LXYZ, KPF, BXYZRD 1 KEY, NO PAR, 4-BIT MSG, IPM OFF\"]]" 

現在我使用的代碼是：

var retVal = JsonConvert.DeserializeObject<List<string>>(string); 

這裏串是上面顯示的那個。

而且我得到異常：

Error reading string. Unexpected token: StartArray. Path '[0]', line 1, position 2. 

爲什麼會出現這種異常？我對JSON很新。

Answer 1

因爲您的模型的類型爲List<List<string>>。

Answer 2

看here，之後嘗試

string str = "[[\"XYZ40E\",\"D  XYZ-12572\",\"XYZ, XYZ HARDWARE END ITEM, XYZ40 (REV D) IXYZ SE KPD\"],[\"5.001.0.045\",\"M  XYZ-14280\",\"PROGRAMMING AND CONFIGURING IXYZ SE XYZ\"],[\"222TTEK0000\",\"A  XYZ-14631\",\"XYZ, XYZ40, MULTIXYZ, SE REV D, XYZ, STD XYZ, STD, XYZ, PIG, BLK, STD 1 SECURITY, LED RED, FLASH GRN, BZR ON, IPM OFF, KPF-4-BIT, 32 BIT\"],[\"4505-104-10\",\"E  XYZ-10728\",\"LBL, PROD, MULTICLASS SE XYZ40, REV D XYZ\"],[\"4505-105-10\",\"D  XYZ-10850\",\"LBL, XYZ SIDE SHPNG, MULTIXYZ SE XYZ40, REV D XYZ\"],[\"XYZ-GRPC-003N\",\"B  XYZ-11880\",\"CFG PFL, LF STD, HF XYZ\\/SIO\\/XYZ, XYZG, LED RED, FLXYZ GRN, BZR ON, CSN 34-BIT LXYZ, KPF, BXYZRD 1 KEY, NO PAR, 4-BIT MSG, IPM OFF\"]]" 
var retVal = JsonConvert.DeserializeObject<List<List<string>>>(str);
