SqlDataReader 打印多行，如何拆分？

Question

我想使用 SqlDataReader 从数据库中检索数据。我让它工作，但我的查询 return 多于一行数据，我想将其分开。

这是我的代码

string query = "select title, rating, dor from movie where title like '%"+name+"%';";

using (SqlConnection conn = new SqlConnection(cs))
{
    SqlCommand cmd = new SqlCommand(query, conn);
    conn.Open();

    SqlDataReader reader = cmd.ExecuteReader();

    if (reader.HasRows)
    {
        while (reader.Read())
        {
            Response.Write(reader[0].ToString());
            Response.Write(reader[1].ToString());
            Response.Write(reader[2].ToString());
        }
    }
    else
    {
        Response.Write("No rows found");
    }

    reader.Close();
}

例如.. reader[0].ToString() 是标题，因为它 return 打印了不止一行数据，所以它打印 "title1title2"。有没有办法拆分它，使第 1 行的标题与第 2 行的标题分开？

试试这个

string query = "select title, rating, dor from movie where title like '%"+name+"%';";

using (SqlConnection conn = new SqlConnection(cs))
{
    SqlCommand cmd = new SqlCommand(query, conn);
    conn.Open();

    SqlDataReader reader = cmd.ExecuteReader();

    if (reader.HasRows)
    {
        while (reader.Read())
        {
            Response.Write(reader[0].ToString());
            Response.Write(reader[1].ToString());
            Response.Write(reader[2].ToString());
            Response.Write("------------------------");//whatever separator you want to use
        }
    }
    else
    {
        Response.Write("No rows found");
    }

    reader.Close();
}
