解决方案
解决方案二：
把你的这段代码FileStreamfileStream=newFileStream(filepath,FileMode.Open,FileAccess.Read);byte[]paramBytes=Encoding.UTF8.GetBytes(param);StringBuildersb=newStringBuilder();sb.Append("--"+boundary+"rn");sb.Append("Content-Disposition:form-data;name="Filename"rn");sb.Append("rn");sb.Append("no.gifrn");sb.Append("--"+boundary+"rn");sb.Append("Content-Disposition:form-data;name="folder"rn");sb.Append("rn");sb.Append("/cgi-bin/uploadsrn");sb.Append("--"+boundary+"rn");sb.Append("Content-Disposition:form-data;name="file";filename="no.gif"rn");sb.Append("Content-Type:application/octet-streamrn");sb.Append("rn");sb.Append("--"+boundary+"rn");sb.Append("Content-Disposition:form-data;name="Upload"rn");sb.Append("rn");sb.Append("SubmitQueryrn");sb.Append("--"+boundary+"--");stringrequestpayload=sb.ToString();byte[]payloadBytes=Encoding.UTF8.GetBytes(requestpayload);byte[]buffer=newByte[checked((uint)Math.Min(4096,(int)fileStream.Length))];webrequest.ContentLength=buffer.Length+paramBytes.Length+payloadBytes.Length;StreamnewStream=webrequest.GetRequestStream();//intbytesRead=0;//while((bytesRead=fileStream.Read(buffer,0,buffer.Length))!=0)newStream.Write(paramBytes,0,paramBytes.Length);newStream.Write(payloadBytes,0,payloadBytes.Length);newStream.Write(buffer,0,buffer.Length);newStream.Close();
改成下面的代码FileStreamfileStream=newFileStream(filepath,FileMode.Open,FileAccess.Read);byte[]buffer=newbyte[fileStream.Length];fileStream.Read(buffer,0,buffer.Length);fileStream.Close();webrequest.ContentLength=buffer.Length;StreamnewStream=webrequest.GetRequestStream();newStream.Write(buffer,0,buffer.Length);newStream.Close();

@sunny906改了但是还是一样参数无效
