Question

我使用以下代码从unicode string创建csv文件：

context.Response.ContentType = "text/csv";
context.Response.ContentEncoding = System.Text.Encoding.Utf8;        
context.Response.AddHeader("Content-Disposition", "attachment; filename=" + fundName + ".csv");
context.Response.BinaryWrite(System.Text.Encoding.Unicode.GetPreamble());                

String output ="";        
output += "Name, callNumber" + "\n";
String output ="علی,34343555" + "\n";     
context.Response.Write(output);

问题是unicode字符无法正确显示“علی”。

感谢任何指南。问候阿里

Answer 1

代码存在一些问题。

context.Response.BinaryWrite(System.Text.Encoding.Unicode.GetPreamble());为UTF-32 而不是 UTF-8写入BOM。
输出变量定义了两次。

我建议尝试这个：

context.Response.ContentType = "text/csv";
context.Response.ContentEncoding = System.Text.Encoding.Utf8;        
context.Response.AddHeader("Content-Disposition", "attachment; filename=" + fundName + ".csv");

String output ="";        
output += "Name, callNumber" + "\n";
output +="علی,34343555" + "\n";     
context.Response.Write(output);
context.Response.End()

我宁愿使用streamwriter来使用UTF-8编码来编写unicode字符。片段：

 using (StreamWriter sw = new StreamWriter(new FileStream("c:/Temp.csv", FileMode.Create), Encoding.UTF8))
            {
                    sw.WriteLine(string.Join(",", s));
            }

只需使用它即可编写Unicode CSV文件：

File.WriteAllText("path/to/file.csv", yourString, Encoding.Unicode);

Answer 4

Response.Clear();
Response.AppendHeader("Content-Type", "Application/vnd.ms-excel");
Response.ContentEncoding = Encoding.UTF8;
Response.AppendHeader("Content-Disposition", "attachment; filename=filename1.csv");
var data = Encoding.UTF8.GetBytes("your content with chinese characters");
var result = Encoding.UTF8.GetPreamble().Concat(data).ToArray();
var str = Encoding.UTF8.GetString(result);
Response.Write(str);
Response.Flush();
Response.SuppressContent = true;

在c＃中将unicode字符串写入csv
