How to auto-generate a C# class file from a JSON o

问题:

Given the following JSON object,

form = {
  \"name\": \"\",
  \"address\": {
    \"street\": \"\",
    \"city\": \"\",
    \"province\": \"\",
    \"postalCode\": \"\",
    \"country\": \"\"
  },
  \"phoneDay\": \"\",
  \"phoneCell\": \"\",
  \"businessName\": \"\",
  \"website\": \"\",
  \"email\": \"\"
}

what is a tool to auto-generate the following C# class?

public class ContactInfo
{
    public string Name { get; set; }
    public Address Address { get; set; }
    public string PhoneDay { get; set; }
    public string PhoneCell { get; set; }
    public string BusinessName { get; set; }
    public string Website { get; set; }
    public string Email { get; set; }
}

public class Address
{
    public string Street { get; set; }
    public string City { get; set; }
    public string Province { get; set; }
    public string PostalCode { get; set; }
    public string Country { get; set; }
}

We have already looked at these questions:

回答1:

Three options:

• Use the free json2csharp web tool without installing anything.

• If you have Web Essentials in Visual Studio, use Edit > Paste special > paste JSON as class.

• Use the free jsonclassgenerator.exe

Pros and Cons:

• jsonclassgenerator converts to PascalCase but the others do not.

回答2:

Visual Studio 2012 (with ASP.NET and Web Tools 2012.2 RC installed) supports this natively.

Visual Studio 2013 onwards have this built-in.

If you install Web Essentials into Visual studio you can go to Edit => Past special => paste JSON as class.

That is probably the easiest there is.
