How do I parse Json with an invalid character for a field name? e.g. { “file/folder”: “/Shared/Salesforce/asdf.txt” } with Newtonsoft?

问题

I received the following JSON from a webservice. How do I parse the following JSON in Netwtonsoft?

{ "file/folder": "/Shared/Salesforce/asdf.txt" } 
   ^^^^^^^^^^
   ^^^^^^^^^^
   ^^^^^^^^^^---that is my problem

Note that the field name has a forward slash, which is invalid for C# when used as a field name. (Newtownsoft does automatic mappings between JSON names and C# fields)

The code I have is

       JsonSerializerSettings set = new JsonSerializerSettings();
        List<UserAudit> usrs = JsonConvert.DeserializeObject<List<UserAudit>>(statusResult );

        foreach (var item in usrs)
        {
            Console.WriteLine(item.username + " " + item.ip_address);
        }

Note how all NewtownSoft needs is the same name for the Javascript object in C#. It handles all the conversion.

 public class UserAudit
 {         

    public string username;
    public string filefolder;  // <----- HOW DO I SET THIS VARIABLE?  "file/folder" is invalid 
    public string transaction;
    public string access;
    public string time;

}

Additional research

I looked at the overload for JsonConvert.DeserializeObject<List<UserAudit>>(statusResult); and didn't see a direct way to rename or reformat the data when it comes in. I looked at both JsonSerializerSettings, and JsonConverters.

回答1:

You want to use JSON attributes to specify the name of the property to map to the model.

public class UserAudit
{
    [JsonProperty("username")]
    public string UserName { get; set; }

    [JsonProperty("file/folder")]
    public string FileFolder { get; set; }

    [JsonProperty("transaction")]
    public string Transaction { get; set; }

    [JsonProperty("access")]
    public string Access { get; set; }

    [JsonProperty("time")]
    public string Time { get; set; }
}

It's common with most serializers to look for attributes to define how they should serialize/deserialize.

Change it from this.

    "/Shared/Salesforce/asdf.txt"

to this

    @"/Shared/Salesforce/asdf.txt"
