c#排序程序

在对SQL表格进入添加操作时，添加完毕后，打开SQL 2005中的相应表格
发现，ID的排序并不是按照从0-399的顺序排列的。请问是怎么回事？怎样可以解决？
以下是代码
SqlCommand SqlCommand_delete = new SqlCommand();
  SqlCommand_delete.Connection = con;
  SqlCommand_delete.CommandText = command_delete;
  SqlCommand_delete.ExecuteNonQuery();

  for (int i = 0; i < 400; i++)
  {
  ID = i;
  string command = "insert into TKdata values('"
  + ID + "','"
  + dataname + "','"
  + DataID + "','"
  + time + "','"
  + QWcode + "','"
  + QYcode + "','"
  + SDcode + "','"
  + QWvalue + "','"
  + QYvalue + "','"
  + SDvalue + "','"
  + Valid + "','"
  + Remark + "')";

  // string command = "delete from student where name='" + "艾未华" + "' and age='" + "999" + "'";


  SqlCommand sqlCommand = new SqlCommand();
  sqlCommand.Connection = con;
