Getting in View current controller, action and id in View
string controller = ViewContext.RouteData.Values["controller"].ToString();
string action = ViewContext.RouteData.Values["action"].ToString();

Getting current controller, action and id in Controller
string actionName = this.ControllerContext.RouteData.Values["action"].ToString();
string controllerName = this.ControllerContext.RouteData.Values["controller"].ToString();

In web.config > system.web
modes: On, Off, RemoteOnly
<!--On - display Views/Shared/Error.cshtml only rendered when there is an exception, 404 is not included in this custom error -->
<customErrors mode="RemoteOnly"></customErrors>

This applies whenever the server hits 500 or 404 errors. Not good in debugging but good in production. In system.webServer

<!--errorMode="DetailedLocalOnly" display only to remote clients-->
    <!--errorMode="Custom" display to all both local and remote -->
    <httpErrors errorMode="Custom" existingResponse="Replace">
      <remove statusCode="404" subStatusCode="-1" />
      <remove statusCode="500" subStatusCode="-1" />
      <error statusCode="404" path="404.html" responseMode="File" />
      <error statusCode="500" path="500.html" responseMode="File" />
    </httpErrors>

Note: adding the second block will override the first block

Beside “Debug” there is a dropdown, click and select “Configuration Manager”. In “Active Solution Configuration” select “New” then add a name like “Testing” and “Select copy settings from” preferrably copy settings from Release.

Right click “web.config” and select “Add Config Transform”. This will create Web.Testing.config.


<appSettings>
    <add key="webpages:Version" value="3.0.0.0" />
    <add key="webpages:Enabled" value="false" />
    <add key="ClientValidationEnabled" value="true" />
    <add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>


Create another config file like AppSettings.config and in web.config > appSettings, add configSource attribute and specify the file

<appSettings configSource="AppSettings.config"></appSettings>

This is useful in public repositories and other scenarious where you don’t want to share your other credentials but to specific people only.
Exclude the AppSettings.config from repository

When uploading file to IIS greater than default will lead to
Exception Details: System.Web.HttpException: Maximum request length exceeded.

To solve this problem, we need specify our upload limit the server is allowed to accept say 5MB (1024×5000)
In Web.config > system.web add
<httpRuntime maxRequestLength="5120000" executionTimeout="3600" />

In Web.config > system.webServer
<security>
    <requestFiltering>
        <requestLimits maxAllowedContentLength="5120000" />
    </requestFiltering>
</security>

Note: maxRequestLength and maxAllowedContentLength must match

string path = Server.MapPath("/Uploads/Users/xxxxx/file.png");
if ((System.IO.File.Exists(path)))
{
System.IO.File.Delete(path);
}
