求一个asp.net上传图片的例子？

[submeet]

上传图片后 显示上传成功后 可以加入数据库（sqlserver）
并且可以在img控件上显示上传的图片（显示控件和上传控件 在一个页面上）

[submeet]

其实就是注册 里面一个上传头像的例子

[tonyze]

string imagePath = "";
if (FileUploadImage.HasFile)
{
string FileAndExtName = FileUploadImage.FileName; //获取文件名
string ExtName = " ";
string FileName = " ";
string ContentType = FileUploadImage.PostedFile.ContentType; //获取文件类型
string filepath = Server.MapPath("~/Upfile") + "\\";
int i = FileAndExtName.LastIndexOf("."); //取得文件扩展名
string newext = FileAndExtName.Substring(i);
//上传图片
DateTime now = DateTime.Now;
string newname = DateTime.Now.Year.ToString() + DateTime.Now.Month.ToString() + DateTime.Now.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString();
if (CheckFileType(newext))
{
if (!Directory.Exists(filepath))
{
Directory.CreateDirectory(filepath);
if (Path.HasExtension(FileAndExtName))
{
ExtName = Path.GetExtension(FileAndExtName);
FileName = FileAndExtName.Replace(ExtName, " ");
}
else
{
FileName = FileAndExtName;
}
FileUploadImage.SaveAs(filepath + newname + newext);
}
else
{
if (Path.HasExtension(FileAndExtName))
{
ExtName = Path.GetExtension(FileAndExtName);
FileName = FileAndExtName.Replace(ExtName, " ");
}
else
{
FileName = FileAndExtName;
}
FileUploadImage.SaveAs(filepath + newname + newext);
}
}
else
{
Response.Write("<script>alert('图片格式不正确！')</script>");
return;
}
imagePath = "~/Upfile/" + newname + newext;
}
else
{
imagePath = "无";
}
bool CheckFileType(string ext)//判断上传图片扩展名
{
switch (ext.ToLower())
{
case ".gif":
case ".png":
case ".jpg":
case ".jpeg":
case ".bmp":
return true;
default:
return false;
}
}
这是显示图片的代码：
function GetImagePath()
{
var upload = document.getElementById("ctl00_ContentPlaceHolder1_FileUploadImage");
var image = document.getElementById("ctl00_ContentPlaceHolder1_Image1");
var uploadValue = upload.value.toString();
//debugger
var i =uploadValue.lastIndexOf('.');
var houZui = uploadValue.substring(i);
if((houZui.toLowerCase()!=".jpg")&&(houZui.toLowerCase()!=".bmp"))
{
alert("您输入的图片格式不正确");return false;
}
image.src=upload.value;
}

把图片路径保存到数据库，图片已经上传了

[submeet]

那一句你保存了 我怎么没有看见啊

[tonyze]

if (CheckFileType(newext))
{
if (!Directory.Exists(filepath))
{
Directory.CreateDirectory(filepath);
if (Path.HasExtension(FileAndExtName))
{
ExtName = Path.GetExtension(FileAndExtName);
FileName = FileAndExtName.Replace(ExtName, " ");
}
else
{
FileName = FileAndExtName;
}
FileUploadImage.SaveAs(filepath + newname + newext);
}
else
{
if (Path.HasExtension(FileAndExtName))
{
ExtName = Path.GetExtension(FileAndExtName);
FileName = FileAndExtName.Replace(ExtName, " ");
}
else
{
FileName = FileAndExtName;
}
FileUploadImage.SaveAs(filepath + newname + newext);
}
}
