复制代码 代码如下:

if (FileUpload1.HasFile)

try

{

FileUpload1.SaveAs("d:luceneData" + FileUpload1.FileName);

Label1.Text = "File name: " +

FileUpload1.PostedFile.FileName + "<br>" +

FileUpload1.PostedFile.ContentLength + " kb<br>" +

"Content type: " +

FileUpload1.PostedFile.ContentType;

}

catch (Exception ex)

{

Label1.Text = "ERROR: " + ex.Message.ToString();

}

else

{

Label1.Text = "You have not specified a file.";

}

还可以在web.config文件中，突破默认上传限制的4MB，比如

<httpRuntime

executionTimeout="110"

maxRequestLength="11000"

requestLengthDiskThreshold="80"

useFullyQualifiedRedirectUrl="false"

minFreeThreads="8"

minLocalRequestFreeThreads="4"

appRequestQueueLimit="5000"

enableKernelOutputCache="true"

enableVersionHeader="true"

requireRootedSaveAsPath="true"

enable="true"

shutdownTimeout="90"

delayNotificationTimeout="5"

waitChangeNotification="0"

maxWaitChangeNotification="0"

enableHeaderChecking="true"

sendCacheControlHeader="true"

apartmentThreading="false" />

设置maxRequestLenth属性，这里为11000KB，即11MB。

而对于多文件上传，也很简单，比如一个例子

string filepath = "d:luceneData";

HttpFileCollection uploadedFiles = Request.Files;

for (int i = 0; i < uploadedFiles.Count; i++)

{

HttpPostedFile userPostedFile = uploadedFiles[i];

try

{

if (userPostedFile.ContentLength > 0)

{

Label1.Text += "<u>File #" + (i + 1) +

"</u><br>";

Label1.Text += "File Content Type: " +

userPostedFile.ContentType + "<br>";

Label1.Text += "File Size: " +

userPostedFile.ContentLength + "kb<br>";

Label1.Text += "File Name: " +

userPostedFile.FileName + "<br>";

userPostedFile.SaveAs(filepath + "" +

System.IO.Path.GetFileName(userPostedFile.FileName));

Label1.Text += "Location where saved: " +

filepath + "" +

System.IO.Path.GetFileName(userPostedFile.FileName) +

"<p>";

}

}

catch (Exception Ex)

{

Label1.Text += "Error: <br>" + Ex.Message;

}

}

}
