文件類型驗(yàn)證
protected void Button1_Click(object sender, EventArgs e)
{
if (FileUpload1.HasFile)
{
fileExt = System.IO.Path.GetExtension(FileUpload1.FileName);
if (fileExt == ".jpg" || fileExt == ".gif")
{
try
{
FileUpload1.SaveAs(Server.MapPath("upload") + "\\" + FileUpload1.FileName);
Label1.Text = "客戶端路徑：" + FileUpload1.PostedFile.FileName + "<br>" +
"文件名：" + System.IO.Path.GetFileName(FileUpload1.FileName) + "<br>" +
"文件擴(kuò)展名：" + System.IO.Path.GetExtension(FileUpload1.FileName) + "<br>" +
"文件大?。? + FileUpload1.PostedFile.ContentLength + " KB<br>" +
"文件MIME類型：" + FileUpload1.PostedFile.ContentType + "<br>" +
"保存路徑：" + Server.MapPath("upload") + "\\" + FileUpload1.FileName;
}
catch (Exception ex)
{
Label1.Text = "發(fā)生錯(cuò)誤：" + ex.Message.ToString();
}
}
else
{
Label1.Text = "只允許上傳jpg、gif文件！";
}
}
else
{
Label1.Text = "沒有選擇要上傳的文件！";
}
}
上傳
protected void Button1_Click(object sender, EventArgs e)
{
if (FileUpload1.HasFile)
{
try
{
FileUpload1.SaveAs(Server.MapPath("upload") + "\\" + FileUpload1.FileName);
Label1.Text = "客戶端路徑：" + FileUpload1.PostedFile.FileName + "<br>" +
"文件名：" + System.IO.Path.GetFileName(FileUpload1.FileName) + "<br>" +
"文件擴(kuò)展名：" + System.IO.Path.GetExtension(FileUpload1.FileName) + "<br>" +
"文件大小：" + FileUpload1.PostedFile.ContentLength + " KB<br>" +
"文件MIME類型：" + FileUpload1.PostedFile.ContentType + "<br>" +
"保存路徑：" + Server.MapPath("upload") + "\\" + FileUpload1.FileName;
}
catch (Exception ex)
{
Label1.Text = "發(fā)生錯(cuò)誤：" + ex.Message.ToString();
}
}
else
{
Label1.Text = "沒有選擇要上傳的文件！";
}
}
補(bǔ)充上傳限制
<system.web>
<httpRuntime maxRequestLength="40690" executionTimeout="6000" />
</system.web>
maxRequestLength表示可上傳文件的最大值，executionTimeout表示ASP.NET關(guān)閉前允許發(fā)生的上載秒數(shù)。
