推荐答案

(#bfile").val(); var data ="file_name =" + file_name; var file = document.getElementById(''bfile'').files [0]; var file_binary = file.getAsBinary(); var file_size = file.fileSize; var file_text = file.getAsText("); alert(''file:''+ file_binary); alert(''文件大小:''+ file_size); data ="file_name =" + file_name +& file_binary =" + file_binary; ajaxlocalcall2(null，"POST"，``@ Url.Content(〜/AppAttachments/file_upload")，数据，"，"，" html，" oncontactinfosave); }

("#bfile").val(); var data = "file_name=" + file_name; var file = document.getElementById(''bfile'').files[0]; var file_binary = file.getAsBinary(); var file_size = file.fileSize; var file_text = file.getAsText(""); alert(''file :'' + file_binary); alert(''file size:'' + file_size); data = "file_name=" + file_name + "&file_binary=" + file_binary; ajaxlocalcall2(null, "POST", ''@Url.Content("~/AppAttachments/file_upload")'', data, "", "", "html", "oncontactinfosave"); }

尝试一下

try this

HttpPostedFile myFile = filUpload.PostedFile;
                int nFileLen = myFile.ContentLength;
                if (nFileLen == 0)
                {
                    lblOutput.Text = "There wasn't any file uploaded.";
                    return;
                }

尝试一下:

在web.config文件中，增加HttpRunTime的"maxRequestLength"属性.
喜欢

Try this:

In web.config file increase the "maxRequestLength" property of HttpRunTime.
like

<httpRuntime maxRequestLength="1024000"/>
