Question

I am unable to open the file just after creating the file in c# webservice code .
The directory is not present initially. So the program creates the directory and the file. Then tries to open the file to write a line. But it fails to open the file. The error is the file is open in another process.

I tried to open the file from windows explorer. the file opens but error message is still coming.
I tried to delete the folder C:\Test, it says file is open is in WebDev.WebDevServer40.exe

Any help please.

[WebMethod]
    public string saveFileUploaderName(string name)
    {
        string path = "c:\\Test";
        string filename = "Test.txt";
        string completeFileName = Path.Combine(path,filename);
        if(!File.Exists(completeFileName))
        {
            Directory.CreateDirectory(path);
            File.Create(completeFileName);
        }
        StreamWriter writer = File.AppendText(completeFileName);
        writer.WriteLine(name);
        writer.Flush();
        writer.Close();
return "success";
}

File.Create returns a stream, but you’re discarding it.
So (I think!) you either need to use the returned stream, or explicitly close it before trying to open a new stream to the same file.
