Answer 1

If you intend to deserialize entire Json, your class definition needs some changes. For example,

public class ContactDetail
{
    public string BKPLZ { get; set; }
    public string Action { get; set; }
    public string GBDEP { get; set; }
    public string PERNR { get; set; }
    public string AddressType { get; set; }
    public string BKORT { get; set; }
}

public class ContactDetails
{
    public List<ContactDetail> ContactDetail { get; set; }
}

public class BankDetail
{
    public string ZBANKGRP { get; set; }
    public string EMFTX { get; set; }
    public string BANKN { get; set; }
    public string Action { get; set; }
    public string PERNR { get; set; }
    public string ZZIFSC { get; set; }
    public string ZLSCH { get; set; }
}

public class BankDetails
{
    public BankDetail BankDetail { get; set; }
}

public class BasicDetail
{
    public string ANREX { get; set; }
    public string GBLND { get; set; }
    public string PLANS { get; set; }
    public string FRO { get; set; }
    public string Action { get; set; }
    public string BEGDA { get; set; }
    public string PERNR { get; set; }
    public string IO { get; set; }
    public string WERKS { get; set; }
    public string MASSG { get; set; }
    public string KST01 { get; set; }
    public string GSBER { get; set; }
    public string VORNA { get; set; }
    public string ORT01 { get; set; }
    public string NATIO { get; set; }
    public string NACHIN { get; set; }
    public string PERSK { get; set; }
    public string GESCH { get; set; }
    public string PERSG { get; set; }
    public string ABKRS { get; set; }
    public string BTRTAL { get; set; }
    public string GBDAT { get; set; }
    public string RO { get; set; }
    public string KBU01 { get; set; }
}

public class BasicDetails
{
    public BasicDetail BasicDetail { get; set; }
}

public class EmployeeMasterData
{
    public ContactDetails ContactDetails { get; set; }
    public BankDetails BankDetails { get; set; }
    public BasicDetails BasicDetails { get; set; }
}

public class EmployeeMaster
{
    public List<EmployeeMasterData> EmployeeMasterData { get; set; }
}

public class Root
{
    public EmployeeMaster EmployeeMaster { get; set; }
}

public class RootObject
{
    public Root root { get; set; }
}

Now you could deserialize as

var result = JsonConvert.DeserializeObject<RootObject>(data);

If you intend to deserialize only a part of it, for example, as seen in the OP, the EmployeeMaster alone, you could do the following

var json = JObject.Parse(data);
var result= JsonConvert.DeserializeObject<EmployeeMaster>(json["root"]["EmployeeMaster"].ToString());
