Entity framework core 使用实体框架核心部分更新postgress中的jsonb列

若我的输入只有firstname，我想更新数据列中的fistname并保持其余字段不变。我试过automapper，但没有锻炼。自动映射将null分配给其他属性（Lastname、middlename）。如果属性为null，我不想在输入属性中执行null检查，也不想从db映射字段（很少有字段可以为null，因此很难确定这些字段是否被请求修改）

Can anyone help me on how to do partial update on jsonb column using entity framework core?

I have employee table with jsonb column(data) in postgress. I would like to modify the jsonb column with the input by replacing  modified field and keeping remaining field unchanged.

**Sample Domain and entity Class**
public class EmployeeDomain
{
public GUID id {get;set;}
public Employeeprofile data {get;set;}
}


public class Employeeprofile
{
public string FirstName {get;set;}
public string LastName {get;set;}
Public string MiddleName {get;set;}
}


public class Employee
{
[Column(TypeName="jsonb")]
public Employeeprofile data {get;set;}
}

Thanks,
