如何获取响应头中的content-disposition

将上述需求进行归我给出如下例子代码：

public static void ToDownload(string serverfilpath,string filename)

{

FileStream fileStream = new FileStream(serverfilpath, FileMode.Open);

long fileSize = fileStream.Length;

HttpContext.Current.Response.ContentType = "application/octet-stream";

HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=\"" + UTF_FileName(filename) + "\";");

////attachment --- 作为附件下载

////inline --- 在线打开

HttpContext.Current.Response.AddHeader("Content-Length", fileSize.ToString());

byte[] fileBuffer = new byte[fileSize];

fileStream.Read(fileBuffer, 0, (int)fileSize);

HttpContext.Current.Response.BinaryWrite(fileBuffer);

fileStream.Close();

HttpContext.Current.Response.End();

}
