Post data in .net core

Question

I want to insert data in database this format-

 

{

"userInjuries": {

"UserId": 4,

"UserInjuriesList": [

{

"UserInjuriesTypeId": 4,

"Description": "Over Wegiht",

"Date": "22/7/2020"

},

{

"UserInjuriesTypeId": 4,

"Description": "Over Wegiht",

"Date": "22/7/2020"

}

]

}

}

public InjuerisResult SavePhysicalInjueris([FromBody] ObjectRoot obj_parameter)
{
InjuerisResult obj_result = new InjuerisResult();
try
{
if (obj_parameter == null)
{
obj_result.Response = 2;
obj_result.ErrorMessage = " object is null";
}
else
{
List<TblInjurie> list_Injurie = new List<TblInjurie>();
string json = Request.Form["UserInjuries"]; --- Here error throw(incorrect content-type: application/json-patch+json)
UserInjuries list = JsonConvert.DeserializeObject<UserInjuries>(json);
foreach (var res in list.UserInjuriesList)
{
var obj_tblInjurie = new TblInjurie();
obj_tblInjurie.Date = DateTime.ParseExact(res.Date, "d/M/yyyy", CultureInfo.InvariantCulture);
obj_tblInjurie.Description = res.Description;
obj_tblInjurie.UserInjuriesTypeId = res.UserInjuriesTypeId;
obj_tblInjurie.UserId = res.UserId;
obj_tblInjurie.IsActive = true;
obj_tblInjurie.UpdatedDate = DateTime.UtcNow;
list_Injurie.Add(obj_tblInjurie);
}
_context.TblInjurie.AddRange(list_Injurie);
_context.SaveChanges();
}
obj_result.Response = 1;
obj_result.ErrorMessage = "No Error Found";
}
catch (Exception ex)
{
obj_result.Response = 0;
obj_result.ErrorMessage = "Internal Server Error";
}
return obj_result;
}
It's me model code.
public class ObjectRoot
{
public UserInjuries UserInjuries { get;set; }
}
public class UserInjuries
{
//public string InjuriesDetails { get; set; }
public List<InjerisDetail> UserInjuriesList { get; set; }
}
[Table("TblInjurie")]
public class InjerisDetail
{
public int? UserId { get; set; }
public int UserInjuriesTypeId { get; set; }
public string Description { get; set; }
public bool? IsActive { get; set; }
[Column(TypeName = "date")]
public string Date { get; set; }
}

Please check and resolve issue.
