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;
}
}
}
