Re: upload image

Try this:

ASP.NET Syntax (Toggle Plain Text)
protected void Button1_Click(object sender, EventArgs e)
    {
       if(FileUpload1.HasFile)
        {
            string fileName = FileUpload1.FileName;
            string fileExtention = fileName.Substring(fileName.LastIndexOf("."), (fileName.Length - fileName.LastIndexOf(".")));
            string newFileName = User.Identity.Name + fileExtention;
            string imagefolder=Server.MapPath("~/Images/");
            string targetFileName = imagefolder + newFileName;
            FileUpload1.SaveAs(targetFileName);
            Label1.Text = "File Uploaded Successfully";
            Response.Redirect("userprofile.aspx");
        }
        else
        {
            Label1.Text = "Please select a file first";
        }
}
protected void Button1_Click(object sender, EventArgs e)
    {
       if(FileUpload1.HasFile)
        {
            string fileName = FileUpload1.FileName;
            string fileExtention = fileName.Substring(fileName.LastIndexOf("."), (fileName.Length - fileName.LastIndexOf(".")));
            string newFileName = User.Identity.Name + fileExtention;
            string imagefolder=Server.MapPath("~/Images/");
            string targetFileName = imagefolder + newFileName;
            FileUpload1.SaveAs(targetFileName);
            Label1.Text = "File Uploaded Successfully";
            Response.Redirect("userprofile.aspx");
        }
        else
        {

 string imagefolder =Server.MapPath("Photos");
                string path;
                string savepath;

                fileup1.PostedFile.SaveAs(savepath);
 string imagefolder =Server.MapPath("Photos");
                string path;

Hi dear,

Your code is correct accept few problems related to it:
1. The code path = Path.Combine(imagefolder, Request.PhysicalApplicationPath); creates a wrong path, please chnage it code to
path = Path.Combine(Request.PhysicalApplicationPath, imagefolder);
2. The file name (Username in this case) is missing the extension, so when system try to save file it would generate errors.
3. Please check path should actually exist before you save file.
4. The username can have special charachers like '\' which need to be removed.

rest of your code is fine.
You can use following code for reference

ASP.NET Syntax (Toggle Plain Text)
 protected void Button1_Click(object sender, EventArgs e)
    {
        String imagefolder = "images";
        String path;
        String savepath;
 
 
        if (FileUpload1.HasFile)
        {
            path = Path.Combine(Request.PhysicalApplicationPath, imagefolder);
            if (Directory.Exists(path))
            {
                savepath = Path.Combine(path, User.Identity.Name.ToString().Replace(@"\", "_") + "__" + Path.GetFileName(FileUpload1.FileName.ToString()));
                FileUpload1.SaveAs(savepath);
                Label1.Text = "Done";
                Response.Redirect("userprofile.aspx");
            }
            else
            {
                Label1.Text = "Error: file path do not exist";
            }
 
        }
        else
        {
            Label1.Text = "Select a file";
        }
    }
 protected void Button1_Click(object sender, EventArgs e)
    {
        String imagefolder = "images";
        String path;
        String savepath;


        if (FileUpload1.HasFile)
        {
            path = Path.Combine(Request.PhysicalApplicationPath, imagefolder);
            if (Directory.Exists(path))
            {
                savepath = Path.Combine(path, User.Identity.Name.ToString().Replace(@"\", "_") + "__" + Path.GetFileName(FileUpload1.FileName.ToString()));
                FileUpload1.SaveAs(savepath);
                Label1.Text = "Done";
                Response.Redirect("userprofile.aspx");
            }
            else
            {
                Label1.Text = "Error: file path do not exist";
            }

        }
        else
        {
            Label1.Text = "Select a file";
        }
    }
