Code:
string FileName = Path.GetFileNameWithoutExtension(customerImage.ImageFile.FileName);
string FileExtension = Path.GetExtension(customerImage.ImageFile.FileName);
FileName = DateTime.Now.ToString("yyyyMMdd") + "-" + FileName.Trim() + FileExtension;
string UploadPath = ConfigurationManager.AppSettings["UserImagePath"].ToString();
customerImage.Image = UploadPath + FileName;
customerImage.ImageFile.SaveAs(customerImage.Image);
Problematic line:
string FileName = Path.GetFileNameWithoutExtension(customerImage.ImageFile.FileName);
Error: UPLOAD IMAGE ERROR
PLEASE HELP IM A COLLEGE STUDENT AND THIS IS FOR A FINAL PROJECT:((((((((((
You have a object reference error (Null Reference Exception),most probably the file upload control has not been initialized properly or there is not file attached to the control when sending the request to server side.
If customerImage is a ASP File Upload control you can access the file name like below:
FileUpload1.FileName
Pleas see below sample: For the HTML
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Button ID="Button1" runat="server" Text="Upload" onclick="Button1_Click"/>
<br />
<asp:Image ID="Image1" runat="server" />
For Server Side
protected void Button1_Click(object sender, EventArgs e) {
StartUpLoad();
}
private void StartUpLoad() {
//get the file name of the posted image
string imgName = FileUpload1.FileName;
//sets the image path
string imgPath = "ImageStorage/" + imgName;
//get the size in bytes that
int imgSize = FileUpload1.PostedFile.ContentLength;
//validates the posted file before saving
if (FileUpload1.PostedFile != null && FileUpload1.PostedFile.FileName != "") {
// 10240 KB means 10MB, You can change the value based on your requirement
if (FileUpload1.PostedFile.ContentLength > 10240) {
Page.ClientScript.RegisterClientScriptBlock(typeof(Page), "Alert", "alert('File is too big.')", true);
} else {
//then save it to the Folder
FileUpload1.SaveAs(Server.MapPath(imgPath));
Image1.ImageUrl = "~/" + imgPath;
Page.ClientScript.RegisterClientScriptBlock(typeof(Page), "Alert", "alert('Image saved!')", true);
}
}
}
Try this and see what is wrong with your code.
