    Hello I want to upload file from webservice not WCF.I am using C# and consuming it with web application.From web application send file,and service will accept that file(text file) and place in upload folder of website/or given location.

    1> Wrote following code in webservice

    public void UploadFile()
    FileStream targetStream = null;

    Stream sourceStream = FileByteStream;

    string uploadFolder = @"D:\UploadFile";

    string filePath = Path.Combine(uploadFolder, @"C:\Users\maya\Desktop\test.txt");

    using (targetStream = new FileStream(filePath, FileMode.Create,
    FileAccess.Write, FileShare.None))
    //read from the input stream in 65000 byte chunks

    const int bufferLen = 65000;
    byte[] buffer = new byte[bufferLen];
    int count = 0;
    while ((count = sourceStream.Read(buffer, 0, bufferLen)) > 0)
    // save to output stream
    targetStream.Write(buffer, 0, count);

    is the file is already present on server or on client ? from where you want to picked it ? if the file is already present on client, then you can not directly upload it without file selection it may treat as malicious activity.
    Web service is always run on IIS (means on server) it does not have a access of Client machine.
