添加对.dll asp.net的引用

Question

I have a simple question about adding references to a .NET project. I'm adding reCAPTCHA to a website and i have downloaded the dll.

After setting the reference to the dll i build and run the project and gets this error:

[ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.]
   System.Reflection.Module._GetTypesInternal(StackCrawlMark& stackMark) +0
   System.Reflection.Assembly.GetTypes() +96
   StarSuite.Core.Settings.GetSingletonInstancesOfBaseType(Type baseType, String staticMethodName, Type returnType) +149

[ApplicationException: Unable to load types from 'Recaptcha, Version=1.0.5.0, Culture=neutral, PublicKeyToken=9afc4d65b28c38c2'. LoaderExceptions: [FileNotFoundException: Could not load file or assembly 'System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.]
]

What am i missing, why do i get this error?

Answer 1

Sorry if the question is silly...Is it your web project MVC? It seems that If you're using web form based project you shouldn't use that component since it relies on mvc assemblies (maybe there is a web form version?).

For people finding this whilst searching for a fix for Umbraco, the fix can be found here:

http://our.umbraco.org/forum/developers/xslt/19383-referencing-catcha-dll-breaks-xslt

The same fix can be applied to websites that are not running Umbraco.

Summary to save you having to read the whole forum post, add this to your web config:

<runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35"/>
                <bindingRedirect oldVersion="1.0.0.0"
          newVersion="2.0.0.0"/>
            </dependentAssembly>
        </assemblyBinding>
    </runtime>

Answer 3

File Not Found :

This is you reason - its in the output:

FileNotFoundException

Double check where your reference is pointing to

您是否在项目的引用下添加了DLL，以便将其包含在构建中？
