The Win Forms application contains only a single form which contains the controls one textbox and two buttons used in conjunction with an OpenFileDialog control and code necessary to select and upload files through the web service. 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.
This code just saved me on a current project and I've used it in the past as well. No config file changes needed either. I'd vote for more that 5 stars if I could.
What else can I say. My vote of 5 George Serbanescu Mar George Serbanescu. My vote of 5. My vote of 4 Pallenov 6-Feb It is clear and short. Hi, I tested a solution based on the article. The solution consist obvious in two projects: an web service and a web application that consume the service. But when I deploy on an internal staging server, the web service seems to do nothing it does not throw errors, or I don't know how to catch them in web app an display them, but the file is not uploaded.
More of this, this not clear to me how to implement this in a way that upload a file from my client computer e. My perception is that it uploads a file from the machine where the web app and web server resides e. ServiceSoapClient ; Could you pleae let me know the namespace to be added or reference to be added to solve this.
