HttpHandler在下载时不保留文件名

public class FileDownloadHandler : IHttpHandler
{
    public void ProcessRequest(HttpContext context)
    {
        // 获取文件路径和文件名
        string filePath = "文件路径";
        string fileName = "文件名";

        // 设置响应头
        context.Response.ContentType = "application/octet-stream";
        context.Response.AddHeader("Content-Disposition", "attachment; filename=" + fileName);

        // 将文件发送到客户端
        context.Response.TransmitFile(filePath);
        context.Response.Flush();
        context.Response.End();
    }

    public bool IsReusable
    {
        get { return false; }
    }
}
