<div align="right">---摘自互联网</div>
这里有一个怎样用ASP+上传文件的非常简单例子<br>
<html> <br>
<script language="VB" runat=server><br>
Sub UploadBtn_Click(Sender as Object, E as EventArgs)<br>
<br>
UploadFile.PostedFile.SaveAs(Server.MapPath("test.jpg"))<br>
MyImage.ImageUrl = "test.jpg"<br>
MyImage.Visible = true<br>
<br>
End Sub<br>
<br>
</script><br>
<br>
<body><br>
<br>
<form enctype="multipart/form-data" runat=server><br>
<br>
<h3><br>
<br>
选择上传文件: <input id="UploadFile" type=file runat=server><br>
<br>
<asp:button Text="Upload Me!" OnClick="UploadBtn_Click" runat=server/><br>
<br>
<hr><br>
<br>
<asp:image id="MyImage" Visible=false runat=server/><br>
<br>
</form><br>
<br>
</body><br>
</html><br>
<br>
<br>
Here is a more complex example, which enables you to upload a file, and then using the System.Drawing APIs <br>
to resize/crop the image, overlay a custom text message onto the image, and then save it back out to disk <br>
as a .jpg (note that this sample works with *any* browser). I've written this one in C# -- but you would <br>
obviously be able to use VB or JScript to do it as well:<br>
<br>
<%@ Import Namespace="System.IO" %><br>
<%@ Import Namespace="System.Drawing" %><br>
<%@ Import Namespace="System.Drawing.Imaging" %><br>
<br>
<html><br>
<br>
<script language="C#" runat=server><br>
<br>
void UploadBtn_Click(Object sender, EventArgs e) {<br>
<br>
UploadFile.PostedFile.SaveAs(Server.MapPath("test.jpg"));<br>
ImageEditor.Visible = true;<br>
} <br>
<br>
void UpdateBtn_Click(Object sender, EventArgs e) {<br>
<br>
System.Drawing.Image image = System.Drawing.Image.FromFile(Server.MapPath("test.jpg"));<br>
System.Drawing.Image newimage = new Bitmap(image.Width, image.Height, PixelFormat.Format32bppRGB);<br>
<br>
Graphics g = Graphics.FromImage(newimage);<br>
g.DrawImage(image,0,0,image.Width,image.Height);<br>
Font f = new Font("Lucida Sans Unicode", Int32.Parse(FontSize.SelectedItem.Text));<br>
Brush b = new SolidBrush(Color.Red);<br>
g.DrawString(Caption.Text, f, b, 10, 140);<br>
g.Dispose();<br>
<br>
System.Drawing.Image thumbImage = newimage.GetThumbnailImage(Int32.Parse(Width.Text),Int32.Parse<br>
(Height.Text),null,0);<br>
image.Dispose();<br>
<br>
thumbImage.Save(Server.MapPath("test.jpg"), ImageFormat.JPEG);<br>
}<br>
<br>
</script><br>
<br>
<body><br>
<br>
<form enctype="multipart/form-data" runat=server><br>
