How to insert data into a sql server from data table via stored procedure

public void  InsertDataTable(DataTable dt)
        {
            Int64 result = 0;
            using (SqlConnection con = new SqlConnection(connection))
            {
                con.Open();
                SqlCommand command = con.CreateCommand();
                SqlTransaction transaction;

                // Start a local transaction.
                transaction = con.BeginTransaction("PortingConnection");

                // Must assign both transaction object and con 
                // to Command object for a pending local transaction
                command.Connection = con;
                command.Transaction = transaction;

                try
                {
                    using (SqlBulkCopy bulkCopy = new SqlBulkCopy(con, SqlBulkCopyOptions.Default, transaction))
                        {
                            bulkCopy.DestinationTableName = "DatabaseTable";
                            bulkCopy.BatchSize = 5000;
                            bulkCopy.WriteToServer(dt);
                            bulkCopy.Close();

                        }

                        transaction.Commit();

                                   

                }
                catch (Exception ex)
                {
                    transaction.Rollback();
                    throw ex;
                }
            }



        }

CREATE TYPE DtType AS TABLE
(
    SNO INT, Name VARCHAR(50), Address VARCHAR(max)
)

Create  PROCEDURE spSaveStudentData
@DataTableDetails DtType READONLY
AS
BEGIN
   
            
            --To insert the new records in the table
            INSERT INTO StudentDetails(Sno, Name, Address) 

            SELECT SNO, Name, Address FROM @DataTableDetails 
        
    END
