高分请教 么执行RESPONSE.END()出错?

Question

我的文件是读成2进制流,正常没问题,供你参考
Response.ContentType="Application/unknown";
Response.AddHeader("Content-Disposition:", "attachment; filename=" + HttpUtility.UrlEncode(delete.FileName.ToString())); 
byte[] file = (byte[])delete.HousePic;
Response.BinaryWrite(file);
Response.Flush();
Response.End();

Answer 1

Response.BinaryWrite(file);
Response.Flush();
Response.End();
----------------| transfer to:
Response.BinaryWrite(file);
Response.End();

Answer 2

delete是我自己建的类,没什么关系,主要是看方法,Response.BinaryWrite(file);file的类型是Byte[]

Answer 3

用try
catch看一下。会出什么错。
