I must consome web service (json).
I build a communication with serialization / deserialization with JavaScriptSerializer.
In 99% its works fine, but...
Error details is returned like that:
{"result":"FAIL","error":{"error_code":1,"desc":"INVALID_DATA","details":{"city":["City cannot be blank."]}}}
To handle that i created Class:
public class ErrorObj
{
public int error_code { get; set; }
public string desc { get; set; }
public Dictionary<string, string[]> details { get; set; }
}
But somtethimes 'details' is returned like that:
{"result":"FAIL","error":{"error_code":1,"desc":"ERROR_OPTIONS","details":["Specifying a bank account"]}}
or
{"result":"FAIL","error":{"error_code":1,"desc":"INVALID_DATA","details":[]}}
To handle thi the class should be like that:
public class ErrorObj
{
public int error_code { get; set; }
public string desc { get; set; }
public string[] details { get; set; }
}
How to build object (ErrorObj) to handle all error messages?
Deserialization code:
public static T DeSerializeObjectFromJsonString<T>(string jsonString)
{
T objectOut = default(T);
Type outType = typeof(T);
var obj = (T) new JavaScriptSerializer().Deserialize(jsonString, typeof(T));
return obj;
}
Error message:
System.InvalidOperationException : Type
'System.Collections.Generic.Dictionary`2[[System.String, mscorlib,
Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],

D-Shih :
You may use model object like this.\n\nThe public Dictionary<string, string[]> details { get; set; }, Just use dynamic rather than Dictionary<string, string[]>.\n\nBecause the json string detail is unfixed.\n\npublic class Error\n{\n public int error_code { get; set; }\n public string desc { get; set; }\n public dynamic details { get; set; }\n}\n\npublic class ErrorObj\n{\n public string result { get; set; }\n public Error error { get; set; }\n}\n\n\nIf you want to know,which json did you get? \n\nYou can use detail.GetType(). To check the type is or isn't array.\n\nlike this simple\n\nstring DictJson = \"{\\\"result\\\":\\\"FAIL\\\",\\\"error\\\":{\\\"error_code\\\":1,\\\"desc\\\":\\\"INVALID_DATA\\\",\\\"details\\\":{\\\"city\\\":[\\\"City cannot be blank.\\\"]}}}\";\n\nstring ArrayJson = \"{\\\"result\\\":\\\"FAIL\\\",\\\"error\\\":{\\\"error_code\\\":1,\\\"desc\\\":\\\"ERROR_OPTIONS\\\",\\\"details\\\":[\\\"Specifying a bank account\\\"]}}\";\n\nErrorObj errorobj = DeSerializeObjectFromJsonString<ErrorObj>(ArrayJson);\n\nif (errorobj.error.details.GetType().IsArray)\n{\n //receive array detail\n}\nelse\n{\n //receive Dictionary<> detail\n}\n",
