Question

我正在尝试将数据导出到csv文件，因为数据中有中文字符我必须使用unicode ..但在添加unicode的前导码后，逗号不会被识别为分隔符，所有数据现在都是写到第一列。我不确定是什么问题。下面是我在.ashx文件中编写的代码。

    DataView priceQuery = (DataView)context.Session["priceQuery"];
    String fundName = priceQuery.Table.Rows[0][0].ToString().Trim().Replace(' ', '_');

    context.Response.Clear();
    context.Response.ClearContent();
    context.Response.ClearHeaders();

    context.Response.ContentType = "text/csv";
    context.Response.ContentEncoding = System.Text.Encoding.Unicode;        
    context.Response.AddHeader("Content-Disposition", "attachment; filename=" + fundName + ".csv");
    context.Response.BinaryWrite(System.Text.Encoding.Unicode.GetPreamble());                

    String output = fundName + "\n";        
    output += "Price, Date" + "\n";

    foreach (DataRow row in priceQuery.Table.Rows)
    {
        string price = row[2].ToString();
        string date = ((DateTime)row[1]).ToString("dd-MMM-yy");

        output += price + "," + date + "\n";
    }

    context.Response.Write(output);

Looks like MS Office does not support Unicode csv files.

但是some users reported that tab delimiter works.

我会尝试使用UTF-8而不是Unicode，这会导致分隔符被视为ASCII字符。

在asp.net中编写csv文件
