Importing Data From txt File into sql table

My Data Format is that

2018052605330002200009131

2018052604460002200009231

2018052604430001200009431

For understanding columns in sql table

(Date,20180526,time:0444,Status:0002,Empcode:2000091,MID:31)

here is my code, when i import data then error is coming of input string wast not in a correct format on this line

Int32 empcode = Convert.ToInt32(lines[i].Split(' ')[0].ToString());

whole code is mentioned below

protected void ReadDat(object sender, EventArgs e)
{
// string[] lines = File.ReadAllLines(Server.MapPath("FileUpload1.PostedFile.FileName"));
string[] lines = File.ReadAllLines(Server.MapPath(FileUpload1.PostedFile.FileName));
for (int i = 0; i < lines.Length; i++)
{
Int32 empcode = Convert.ToInt32(lines[i].Split(' ')[0].ToString());
DateTime Date = Convert.ToDateTime(lines[i].Split(' ')[1].ToString() + " " + lines[i].Split(' ')[2].ToString());
int Time = Convert.ToInt32(lines[i].Split(' ')[3]);
int INOUT = Convert.ToInt32(lines[i].Split(' ')[4]);
int MID = Convert.ToInt32(lines[i].Split(' ')[5]);
Insert (empcode,Date,Time,INOUT,MID);
}
}
public void Insert(int empcode, DateTime date, int TIme, int INOUT, int MID)
{
string str = ConfigurationManager.ConnectionStrings[1].ConnectionString;
using (SqlConnection con = new SqlConnection(str))
{
string query = "INSERT INTO HR VALUES(" + empcode + ",'" + date + "'," + TIme + "," + INOUT + "," + MID + ")";
using (SqlCommand cmd = new SqlCommand(query, con))
{
con.Open();
cmd.ExecuteNonQuery();
con.Close();
}
}
}
}
}
