Execute array into DB by Dapper - sql

Question

If string Subject = "Hello"; and int[] Category = new int[] { 1, 3, 5, 7, 9 };
How can i insert above variables into DB with one execute session? (i'm using Dapper)
My sql stored procedure:
CREATE PROCEDURE [dbo].[TKNewTicket]
#Subject nvarchar(max),
#Category int
AS
BEGIN
SET NOCOUNT ON;
DECLARE #ObjectID [int]
INSERT INTO dbo.TKTickets(Subject) VALUES (#Subject)
SET #ObjectID = SCOPE_IDENTITY()
INSERT INTO dbo.TKTicketCategory(TicketId, CategoryId) VALUES(#ObjectID, #Category)
END
GO
My Tables:
CREATE TABLE [dbo].[TKTickets] (
[Id] INT NOT NULL PRIMARY KEY IDENTITY,
[Subject] nvarchar(100) NOT NULL, )
CREATE TABLE [dbo].[TKTicketCategory] (
[Id] INT NOT NULL PRIMARY KEY IDENTITY,
[TicketId] INT NULL,
[CategoryId] INT NULL,
CONSTRAINT [FK_TKTicketCategory_TKTickets] FOREIGN KEY ([TicketId]) REFERENCES [TKTickets]([Id]),
CONSTRAINT [FK_TKTicketCategory_TKCategories] FOREIGN KEY ([CategoryId]) REFERENCES [TKCategories]([Id]), )

Answer 1

I figured out.
public static void NewTicket(string Subject, int[] Categories)
{
using (IDbConnection cnn = new SqlConnection(SqlDataAccess.GetConnectionString()))
{
string sql = #"dbo.InsertNewTicket #Subject";
var ObjectId = cnn.Query<int>(sql, new { Subject = Subject }).Single();
foreach(int Category in Categories)
{
sql = #"InsertNewTicketCategory #TicketId, #CategoryId";
cnn.Query(sql, new { TicketId = ObjectId, CategoryId = Category });
}
}
}
