read json file data and insert bulk data

Hello,

I want to read json file data with specific json object array and insert bulk data into database in Asp.net Core.

I have two tables in Databse like naming as M203StructureKind, FlhDivision

CREATE TABLE [dbo].[M203StructureKind](

[Id] [int] IDENTITY(1,1) NOT NULL,

[Code] [nvarchar](1) NOT NULL,

[Description] [nvarchar](30) NOT NULL,

[AgencyId] [int] NOT NULL,

[IsActive] [bit] NOT NULL,

[IsDeleted] [bit] NOT NULL,

[AddedBy] [int] NOT NULL,

[AddedOn] [datetime] NOT NULL,

[ModifiedBy] [int] NOT NULL,

[ModifiedOn] [datetime] NOT NULL

)

CREATE TABLE [dbo].[FlhDivision](

[Id] [int] IDENTITY(1,1) NOT NULL,

[Code] [nvarchar](1) NOT NULL,

[Description] [nvarchar](15) NOT NULL,

[AgencyId] [int] NOT NULL,

[IsActive] [bit] NOT NULL,

[IsDeleted] [bit] NOT NULL,

[AddedBy] [int] NOT NULL,

[AddedOn] [datetime] NOT NULL,

[ModifiedBy] [int] NOT NULL,

[ModifiedOn] [datetime] NOT NULL

)

Also i have generated entities from database using asp.net core in models folder

like M203StructureKind.cs

public partial class M203structureKind

{

public int Id { get; set; }

public string Code { get; set; }

public string Description { get; set; }

public int AgencyId { get; set; }

public bool? IsActive { get; set; }

public bool IsDeleted { get; set; }

public int AddedBy { get; set; }

public DateTime AddedOn { get; set; }

public int ModifiedBy { get; set; }

public DateTime ModifiedOn { get; set; }

}

and FlhDivision.cs

public partial class FlhDivision

{

public int Id { get; set; }

public string Code { get; set; }

public string Description { get; set; }

public int AgencyId { get; set; }

public bool? IsActive { get; set; }

public bool IsDeleted { get; set; }

public int AddedBy { get; set; }

public DateTime AddedOn { get; set; }

public int ModifiedBy { get; set; }

public DateTime ModifiedOn { get; set; }

}

Now

I Have MasterData.json file which contains this two tables data with json object.

MasterData.json file contains following contains like

{

"M203StructureKind": [

{

"Code": "1",

"Description": "BRIDGE"

{

"Code": "2",

"Description": "CULVERT"

{

"Code": "3",

"Description": "TUNNEL"

{

"Code": "4",

"Description": "TRAIL BRIDGE"

{

"Code": "5",

"Description": "OTHER"

}

"FlhDivision": [

{

"Code": 1,

"Description": "CFL"

{

"Code": 2,

"Description": "EFL"

{

"Code": 3,

"Description": "WFL"

}

]

}

So, Now i want to insert bulk data into table using POST Api in Asp.net Core. But using foreach loop this is too much lengthy process also time consuming because i have so many tables to insert bulk data into database. So tell me the solution

I have tried using foreach but this is not proper solution

[HttpPut("copyMasterData/{id}")]

public async Task CopyMasterData(int id, bool isCopiedData)

{

try

{

string contentRootPath = _appSettings.MasterJsonPath;

var folderDetails = Path.Combine(Directory.GetCurrentDirectory(), $"wwwroot\\{"MasterData\\masterdata.json"}");

var JSON = System.IO.File.ReadAllText(folderDetails);

dynamic jsonObj = Newtonsoft.Json.JsonConvert.DeserializeObject(JSON);

var response = 0;

foreach (JObject structKind in jsonObj["M203StructureKind"])

{

string code = (string)structKind["Code"];

string description = (string)structKind["Description"];

int agencyId = id;

bool IsActive = true;

bool IsDeleted= false;

int AddedBy = User.GetUserId();

int ModifiedBy = User.GetUserId();

DateTime ModifiedOn = DateTime.Now;

DateTime AddedOn = DateTime.Now;

response = await _m203structkindService.AddAsync(structKind.ToSingle());

}

foreach (JObject flh in jsonObj["FlhDivision"])

{

string code = (string)flh["Code"];

string description = (string)flh["Description"];

int agencyId = id;

bool IsActive = true;

bool IsDeleted = false;

int AddedBy = User.GetUserId();

int ModifiedBy = User.GetUserId();

DateTime ModifiedOn = DateTime.Now;

DateTime AddedOn = DateTime.Now;

response = await _flhdivisionService.AddAsync(flh.ToSingle());

}

return response > 0 ? Ok(new { message = "Master data added successfully." }) : StatusCode(500, "An error occured while adding master data. Please try again...");

}

catch (Exception ex)

{

return StatusCode(500, ResponseMessages.GetErrorMessage(ResponseMessages.MessageType.Add, ex.Message));

}

Tell me the bulk insert with Json Data in Asp.net core POST Api .
