如图格式是比较复杂的json字符串，现在我想把它分离出来，请问各位大佬问怎么实现呢？

这是在vs里的类：
namespace Scheduling
{

public class Rootobject
{
    public Pqxxlist[] pqxxlist { get; set; }
    public string status { get; set; }
}

public class Pqxxlist
{
    public string chiefJudger { get; set; }
    public Case[] cases { get; set; }
    public string courtCode { get; set; }
    public string ajbs { get; set; }
    public string planBeginTime { get; set; }
    public string isPublic { get; set; }
    public string planEndTime { get; set; }
    public string jlid { get; set; }
    public string clerkName { get; set; }
    public string judgerName { get; set; }
    public string tribunalCode { get; set; }
}

public class Case
{
    public string trialNum { get; set; }
    public string caseRegist { get; set; }
    public Caseparty[] caseParties { get; set; }
    public string caseBrief { get; set; }
    public string caseNo { get; set; }
    public string undertakerOrg { get; set; }
    public string undertaker { get; set; }
    public string caseType { get; set; }
}

public class Caseparty
{
    public string type { get; set; }
    public string name { get; set; }
}

}
