Write " Not found! Saturday, January 5, PM. User posted Hi there, Thanks for the reply. User posted I want to do in ASP. The Uploader web service project is an ASP. NET web service project containing a single web service called, " FileUploader "; this web service exposes a single web method called, " UploadFile ". The remainder of the code supplied in this class is used to define the web method used to upload the file; the code is annotated.

The essential process is that, files converted to byte arrays are passed along with the full name of the file not the path including the extension as arguments to the UploadFile web method. The byte array is passed to a memory stream, and a file stream is opened pointing to a newly created file named the name of the original file within the target folder used to store the files.

Once the file stream has been created, the memory stream is written into the file stream and then the memory stream and file stream are disposed of. The web method is setup to return a string; if all goes well, the string returned will read, "OK", if not, the error message encountered will be returned to the caller.

The test application contains a single Windows Form class; this form contains a text box used to display the name of the file selected for upload, a browse button used to launch an open file dialog box which is used to navigate to and select a file for upload, and an upload button which is used to pass the file to web service so that the selected file may be stored on the server.

The next bit of code in the class is private method used to prepare the file for submittal to the web service and to actually make that submittal. The code below is annotated to describe the activity but the essential parts of the operation are to check the file size to see if the web service will accept the file by default, the web server will accept uploads smaller than 4 MB in size, the web config file must be updated in order to support larger uploads , and to convert the file to a byte array.

When everything is ready, the byte array and the name of the file including the extension is passed to an instance of the web service web method. Note that, when setting up the demo, you will have remove and add the web reference back into the project in order for it to work for you.
