webclient - Is there an upload limit when using Web Client in C#?

Question

Using UploadFile("upload.php", "POST", filePath) with WebClient anything over 4mb will not upload. The limit in PHP is set at 48mb. Is there I need to set in C# ?

Answer 1

There is a default maxRequestLength set at 4MB in ASP.NET, you can change it in the web.config.

<configuration>
    <system.web>
        <!-- This will handle requests up to 1024MB (1GB) -->
        <httpRuntime maxRequestLength="1048576" timeout="3600" />
    </system.web>
</configuration>

The length is specified in KB in the config file. If you are using IIS there is an additional limit set at 4MB by IIS.
