aps .net 将二进制流导出

在ASP.NET中将二进制流导出可以通过以下步骤实现：

1. 创建一个HttpResponse对象

HttpResponse response = HttpContext.Current.Response;

2. 设置响应头信息

response.Clear();
response.ClearHeaders();
response.ClearContent();
response.Buffer = true;
response.ContentType = "application/octet-stream";
response.AddHeader("Content-Disposition", "attachment;filename=filename.bin");

其中，Content-Disposition指定了文件名，attachment表示该文件作为附件下载。

3. 将二进制流写入响应

byte[] data = // 二进制数据
response.BinaryWrite(data);

4. 结束响应

response.End();

完整代码示例：

HttpResponse response = HttpContext.Current.Response;
response.Clear();
response.ClearHeaders();
response.ClearContent();
response.Buffer = true;
response.ContentType = "application/octet-stream";
response.AddHeader("Content-Disposition", "attachment;filename=filename.bin");

byte[] data = // 二进制数据
response.BinaryWrite(data);

response.End();
