A. asp上传单个图片的最简单代码是什么
需要三个文件：
第一个（upload.asp）
<% Response.Buffer=True %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>图片上传</title>
</head>
<body background="images/bg.gif" topmargin="30" style=""><div align="center">
<center>
<table border="1" cellspacing="1" style="border-collapse: collapse" bordercolor="#C0C0C0" width="420" id="AutoNumber69" bgcolor="#F5F5F5">
<tr>
<td width="100%" bgcolor="#F5F5F5" bordercolor="#F5F5F5"><form name="form1" method="post" action="uploadsave.asp" enctype="multipart/form-data">
<p align="center"><span style="font-size: 12px">图片上传:</span><br>
<br>
<input type="file" class="f11" name="file1" size="23">
<br>
<br>
<input type=submit name="submit" value="上 传" class=anniu >
<br>
<br>
<span style="font-size: 12px">文件格式为<font color="#EC5106">*.gif,*.jpg,*.jpeg
</font></span></p>
</form></td>
</tr>
</table>
</center>
</body>
</html>
第二个文件（uploadsave.asp）
<% Response.Buffer=True %>
<html>

B. asp 上传图片 代码
我嘴笨 代码上！
protected void UpLoad(object sender, EventArgs e)
{
foreach (UploadedFile file in RadUploadContext.Current.UploadedFiles)
{
string Path = Server.MapPath(@"../../Uploads");
//如果路径不存在，则创建
if (System.IO.Directory.Exists(Path) == false)
{
System.IO.Directory.CreateDirectory(Path);
}
//file.GetName()取得文件名
string filename = file.GetName().ToString();
//取得文件名(包括路径)里最后一个"."的索引
int index = filename.LastIndexOf(".");
//取得文件扩展名
string extendName = filename.Substring(index);
//取得原文件名不包含后缀名
string fileNameFirst = filename.Substring(0, index);
//用当前时间为文件重名名,确保文件名不重复
string datename = DateTime.Now.ToString("yyyyMMddHHmmss");
string newFileName = fileNameFirst + datename + extendName;
//组合路径
Path = Path + "/" + newFileName;
//保存
file.SaveAs(Path, true);
this.dataurl.Visible = true;
this.lab2.Visible = true;
this.FileUpload1.Visible = false;
this.Button3.Visible = false;
this.dataurl.ReadOnly=true;
this.dataurl.Text = newFileName;
//Response.Write("f1：" + fileNameFirst);
//Response.Write("f2：" + Path);
}
}

C. ASP上传图片代码，最简单的
一般上传图片常用的是无组件上传，加我HI帮你看看吧！
