我正在使用另一个 Stack Overflow 问题中的技术将 CSV 文件写入Response输出以供用户打开/保存。该文件在记事本中看起来不错，但是当我在 Excel 中打开它时，重音字符是垃圾。我认为这与字符编码有关，所以我尝试手动将其设置为 UTF-8（默认值StreamWriter）。这是代码：

// This fills a list to enumerate - each record is one CSV line
List<FullRegistrationInfo> fullUsers = GetFullUserRegistrations();

context.Response.Clear();
context.Response.AddHeader("content-disposition",
                           "attachment; filename=registros.csv");
context.Response.ContentType = "text/csv";
context.Response.Charset = "utf-8";

using (StreamWriter writer = new StreamWriter(context.Response.OutputStream))
{
    for (int i = 0; i < fullUsers.Count(); i++)
    {
        // Get the record to process
        FullRegistrationInfo record = fullUsers[i];

        // If it's the first record then write header
        if (i == 0)
            writer.WriteLine(Encoding.UTF8.GetString(
                Encoding.UTF8.GetPreamble()) + 
                "User, First Name, Surname");

        writer.WriteLine(record.User + "," +
                         record.FirstName + "," +
                         record.Surname);
    }
}

context.Response.End();

关于我还需要做什么来正确编码文件以便 Excel 可以查看重音字符的任何想法？

您可能必须在输出的开头写入一个称为字节顺序标记的 UTF-8 指示符，以通知 Excel UTF-8ness。愚蠢的Excel。
