问题描述
小弟现在项目要要用到Request.BinaryRead,byte[]fileData,formData;formData=Request.BinaryRead(Request.ContentLength);无论ContentLength为何值的时候都提示ArgumentException异常,当ContentLength能取到值的时候,这个(Request.BinaryRead)应该能读到数据吧,请大侠们指教,小弟刚参加工作.谢谢
解决方案
解决方案二：
这个问题还没有研究过帮你顶一下
解决方案三：
提供的代码太少了。寻梦Ｅ
解决方案四：
要使用Request.BinaryRead(),提交的表單應該設置enctype為'multipart/form-data',如下,LZ請檢查一下:<formid="up"method=postname=""action="cuscontactatt.asp"enctype="multipart/form-data"></form>
解决方案五：
已经设置了啊:这是代码:(asp.net2.0)1.html部分:<!DOCTYPEhtmlPUBLIC"-//W3C//DTDXHTML1.0Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html><head><title>FCKeditor-UploadersTests</title><scriptlanguage="javascript">functionSendFile(){varsUploaderUrl=cmbUploaderUrl.value;if(sUploaderUrl.length==0)sUploaderUrl=txtCustomUrl.value;if(sUploaderUrl.length==0){alert('PleaseprovideyourcustomURLorselectadefaultone');return;}eURL.innerHTML=sUploaderUrl;txtUrl.value='';frmUpload.action=sUploaderUrl;frmUpload.submit();}functionOnUploadCompleted(errorNumber,fileUrl,fileName,customMsg){switch(errorNumber){case0://NoerrorstxtUrl.value=fileUrl;alert('Fileuploadedwithnoerrors');break;case1://Customerroralert(customMsg);break;case10://CustomwarningtxtUrl.value=fileUrl;alert(customMsg);break;case201:txtUrl.value=fileUrl;alert('Afilewiththesamenameisalreadyavailable.Theuploadedfilehasbeenrenamedto"'+fileName+'"');break;case202:alert('Invalidfile');break;case203:alert("Securityerror.Youprobablydon'thaveenoughpermissionstoupload.Pleasecheckyourserver.");break;default:alert('Erroronfileupload.Errornumber:'+errorNumber);break;}}</script></head><body><tablecellSpacing="0"cellPadding="0"width="100%"border="0"height="100%"><tr><td><tablecellSpacing="0"cellPadding="0"width="100%"border="0"><tr><tdnowrapstyle="height:43px">Selectthe"FileUploader"touse:<br><selectid="cmbUploaderUrl"name="Select1"><optionselectedvalue="asp/upload.asp">ASP</option><optionvalue="php/upload.php">PHP</option><optionvalue="Upload.aspx?type=image">aspx</option></select></td><tdnowrapstyle="height:43px"> </td><tdwidth="100%"style="height:43px">CustomUploaderURL:<BR><inputid="txtCustomUrl"style="WIDTH:100%;BACKGROUND-COLOR:#dcdcdc"disabledtype="text"></td></tr></table><br><tablecellSpacing="0"cellPadding="0"width="100%"border="0"><tr><tdnoWrap><formid="frmUpload"target="UploadWindow"enctype="multipart/form-data"action=""method="post">Uploadanewfile:<br><inputtype="file"name="NewFile"><br><inputtype="button"value="SendittotheServer"onclick="SendFile();"></form></td><tdstyle="WIDTH:16px"> </td><tdvAlign="top"width="100%">UploadedFileURL:<br><INPUTid="txtUrl"style="WIDTH:100%"readonlytype="text"></td></tr></table><br>PostURL:<spanid="eURL"> </span></td></tr><tr><tdheight="100%"><iframename="UploadWindow"width="100%"height="100%"></iframe></td></tr></table></body></html>
