For my web app i have flash component for uploading files. I would like to handle max file size limit on client side without actual sending that file to server. So i need to read that value from config file somehow to send it to client. Some articles i had found said that reading directly config file is not solution, because it can be changed in whole lot of places. So there should be some API call probably, but i cannot find any...
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="1048576" />
</requestFiltering>
</security>
</system.webServer>
I know it is an old question, but it cost me so much time (wasted) that I felt like posting a working solution for those who might come in my path:
Using Microsoft.Web.Administration;
uint uiMaxAllowedContentLength = 0;
using (ServerManager serverManager = new ServerManager())
{
Configuration config = serverManager.GetWebConfiguration("Default Web Site/{{your special site}}");
ConfigurationSection requestFilteringSection = config.GetSection("system.webServer/security/requestFiltering");
ConfigurationElement requestLimitsElement = requestFilteringSection.GetChildElement("requestLimits");
object maxAllowedContentLength = requestLimitsElement.GetAttributeValue("maxAllowedContentLength");
if (null != maxAllowedContentLength)
{
uint.TryParse(maxAllowedContentLength.ToString(), out uiMaxAllowedContentLength);
}
}
Make sure that you first download and install the Microsoft Web Administration package (
PM> Install-package Microsoft.Web.Administration
)
Also, you might need to adjust permission to your web.config file. Give IUSR and IIS_IUSRS at least "Read" permission.
The code is actually from Microsoft site, though to find it took forever! Hopefully I have saved you couple of hours.
