Datagridview超出范围

Question

我想从数据库插入datagridview，但我得到：

  

指数超出范围。必须是非负数且小于   集合。参数名称：index

datagridtampil.ColumnCount = 6;
datagridtampil.Columns.Insert(0, cek);
try
{
    string sql = "select * from "+tipe;
    cmd = new SqlCommand(sql, conn);
    reader = cmd.ExecuteReader();
    if (reader.HasRows)
    {
        int j = 0;
        while (reader.Read())
        {
            for (int i = 0; i <= 5; i++)
            {
                datagridtampil.Rows[j].Cells[i+1].Value = reader[i].ToString();
            }
            j += 1;
        }
    }
}

出了什么问题？

试试这个

datagridtampil.Rows.Clear();
if (reader.HasRows)
{
    int j = 0;
    while (reader.Read())
    {
        j = datagridtampil.Rows.Add()
        for (int i = 1; i < datagridtampil.Columns.Count; i++)
        {
            datagridtampil.Rows[j].Cells[i].Value = reader.GetValue(i-1).ToString();
        }
    }
}
