使用C#将JSON字符串从驼峰大小写转换为Pascal大小写

using Newtonsoft.Json;
using Newtonsoft.Json.Serialization;

public class MyData
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

public class PascalCasePropertyNamesContractResolver : DefaultContractResolver
{
    protected override string ResolvePropertyName(string propertyName)
    {
        return char.ToUpper(propertyName[0]) + propertyName.Substring(1);
    }
}

public class Program
{
    public static void Main()
    {
        var data = new MyData
        {
            FirstName = "john",
            LastName = "doe"
        };

        var settings = new JsonSerializerSettings
        {
            ContractResolver = new PascalCasePropertyNamesContractResolver()
        };

        var json = JsonConvert.SerializeObject(data, settings);
        Console.WriteLine(json);
    }
}
