Question

目前我有这个代码：

 SqlConnection connection = new SqlConnection(@"Data Source=localhost\SQLEXPRESS;Initial Catalog=PSeminar;Integrated Security=true;Trusted_Connection=Yes;MultipleActiveResultSets=true");
        SqlCommand Command = connection.CreateCommand();

        SqlDataReader SQLRD;

        Command.CommandText = "Select * from Attendance";

        connection.Open();
        SQLRD = Command.ExecuteReader();


        //string data = "";

        System.Text.StringBuilder sb = new System.Text.StringBuilder();

        while (SQLRD.Read())
        {

            sb.Append(String.Format("{0}, {1}, {2}, {3}, {4}, {5}, {6}, {7}\n",
            SQLRD[0], SQLRD[1], SQLRD[2], SQLRD[3], SQLRD[4], SQLRD[5], SQLRD[6], SQLRD[7]));
        }

        SQLRD.Close();
        connection.Close();

        byte[] ar = System.Text.Encoding.UTF8.GetBytes(sb.ToString());
        Response.ClearContent();
        Response.ClearHeaders();
        Response.AddHeader("Content.Type", "application/octet-stream");
        Response.AddHeader("Content-Length", ar.Length.ToString());
        Response.AddHeader("Content-Disposition", "attachment; filename=download.csv");
        Response.BinaryWrite(ar);
        Response.Flush();
        Response.End();

目前，如果我导出它，并且字符串中有逗号，它将在csv文件的另一列中，与其他列不同，我该如何解决？希望有人可以帮助我！

Answer 1

CSV“spec”（如果可以调用它）允许文本限定符。因此，您可以执行以下操作：

test,test,"this, and this", test

这是四列数据，第三列包含值[this，and this]。

编辑：将格式字符串修改为以下内容：

"\"{0}\",\"{1}\",\"{2}\",\"{3}\",\"{4}\",\"{5}\",\"{6}\",\"{7}\"\n"

导出包含逗号的csv文件时如何避免错误？
