Issue with saving image file onto server from client machine

Question

I am using the below code to Upload an Image file to a SharePoint Document Library. The code works fine locally but once deployed to server, i get the Exception as file not found.

                String fileToUpload = FlUpldImage.PostedFile.FileName; //@"C:\Users\admin.RSS\Desktop\Photos\me_skype.jpg";
                String documentLibraryName = "SiteAssets";
                if (!System.IO.File.Exists(fileToUpload))
                    throw new FileNotFoundException("File not found.", fileToUpload);

                SPFolder myLibrary = web.Folders[documentLibraryName];

                // Prepare to upload
                Boolean replaceExistingFiles = true;
                String fileName = CheckStringNull(txtFirstName.Text) + CheckStringNull(txtLastName.Text) + CheckDateNull(txtDOB) + System.IO.Path.GetFileName(fileToUpload); ;
                if (fileName.Contains('/'))
                {
                    fileName = fileName.Replace("/", "");
                }
                if (fileName.Contains(':'))
                {
                    fileName = fileName.Replace(":", "");
                }
                FileStream fileStream = File.OpenRead(fileToUpload);
                //Upload document
                SPFile spfile = myLibrary.Files.Add(fileName, fileStream, replaceExistingFiles);
                string url = site.ToString() + "/" + spfile.ToString();
                if (url.Contains("="))
                {
                    url = url.Split('=')[1];
                }
                //Commit
                myLibrary.Update();

The string fileupload contains URL as C:\Users\admin.RSS\Desktop\Photos\me.jpg This URL is actually the client system and the server side code throws exception as file not found. How to handle this issue?

UPDATE:

If i try withot the lines of code that checks if the file exists i.e withoutFileStream fileStream = File.OpenRead(fileToUpload); than i get the exception as as c:\windows\system32\inetsrv\me.jpg cold not be found

To save the file you first need to get it to the server. You are now trying to open a file on the server using the path supplied by the client, basically your looking for the clients file on the server... Kind of explains why it works locally. If your using a ASP.Net FileUPload control one example is to do like this.

   if(FileUpload1.HasFile)
{
int fileLen = FileUpload1.PostedFile.ContentLength;
byte[] input = new byte[fileLen - 1];
input = FileUpload1.FileBytes;

using (MemoryStream memory = new MemoryStream(input))
{
//do what you like with your now uploaded file in memmory...
}

}

Check out this link. Make sure you are using the client api correctly. Also notice the different ways of uploading your file depending on how big the file is.

Why not use just an HTTP PUT?

string filepath = ...
WebRequest request = WebRequest.Create("[Document Library URL]" + "/" + filename);
//Set crediential - either create or use existing
request.Credentials = CredentialCache.DefaultCredentials;
request.Method = "PUT";
byte[] buffer = new byte[1024];
using (Stream stream = request.GetRequestStream())
{
    using (FileStream fs = new FileStream(filepath, FileMode.Open, FileAccess.Read))
    {
        for (int i = fs.Read(buffer, 0, buffer.Length); i > 0; i = fs.Read(buffer, 0, buffer.Length))
        {
            stream.Write(buffer, 0, i);
        }
    }
}
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
response.Close();
if (response.StatusCode == System.Net.HttpStatusCode.Created)
{                       
    //OK
}
else
{
    //Problem
}
