使用C＃将文件上传到Web服务器

Question

I am trying to upload file in web server as following using C#

try
{
    // create WebClient object
    WebClient client = new WebClient();

    string myFile = @"D:\test_file.txt";
    client.Credentials = CredentialCache.DefaultCredentials;

    // client.UploadFile(@"http://mywebserver/myFile", "PUT", myFile);
    client.UploadFile(@"http://localhost/uploads", "PUT", myFile);
    client.Dispose();
}
catch (Exception err)
{
    MessageBox.Show(err.Message);
}

But every time I am getting this error:

The remote server returned an error: (405) Method Not Allowed.

Answer 1

I have solved this using the POST method and server side code:

C# code

try
{
    WebClient client = new WebClient();
    string myFile = @"D:\test_file.txt";
    client.Credentials = CredentialCache.DefaultCredentials;
    client.UploadFile(@"http://localhost/uploads/upload.php", "POST", myFile);
    client.Dispose();
}
catch (Exception err)
{
    MessageBox.Show(err.Message);
}

Server side PHP code upload.php

<?php
    $filepath = $_FILES["file"]["tmp_name"];
    move_uploaded_file($filepath,"test_file.txt");
?>

The error means that the "PUT" method you are using is not allowed by the server. Check the response headers for allowed methods. More info here .

Or check the documentation for the application to which you are trying to upload the file.

Answer 3

the error is showing that you need to register with the service which you are using

in the case of wcf you can register like this

"%WINDIR%\\Microsoft.Net\\Framework\\v3.0\\Windows Communication Foundation\\ServiceModelReg.exe" -r

HTTP Error 405 Method not allowed
