问题 I want to ask that which methods/classes are allowed in Medium Trust. For example, whether these methods are allowed? GetProperties, GetMethods, Activator.CreateInstance, Assembly.Version, AssemblyName.Name Please tell me which methods are allowed. 回答1: GetMethods and Activator.CreateInstance should be allowed IIRC, whilst AssemblyName and Assembly.Version aren't. I've used the first two methods in Medium-Trust environments and the latter two didn't work. Best way is just through trial-and

Does anyone know of another way to compile an expression under medium trust or a workaround to avoid this exception? The code that throws the exception: Expression<Func<object>> efn = Expression.Lambda<Func<object>>(Expression.Convert((plan,typeof(object))); Func<object> fn = efn.Compile(); // Exception thrown here The variable plan is an Expression that represents the following execution plan:

问题 How do I make Lucene.NET 2.3.2 run in a medium trust environment? GoDaddy doesn't like it the way it is. 回答1: I just recently struggled with this, and wanted to update this with a solution I got to work. I pulled down the latest code and built it myself so I could make changes if needed. In the SupportClass.cs file, starting at line 481 there is some code that verifies a file buffer has been flushed using unmanaged code. if (OS.IsWindows) { if (!FlushFileBuffers(fileStream.Handle)) throw new

问题 how do i access Mysql from an ASP.NET 2 site in medium trust mode? My ISP wont allow my site to run under full trust and i've tried many(if not all) mysql apis to connect to the db. All result in either SocketPermission or FileIOPermission errors. i have even tried overriding the trust setting in my web.config. Any ideas? 回答1: Ask them to put the MySQL assemblies in the GAC.

They're going to need to trust the software they're going to be installing to not destroy their servers.

RDLC Medium Trust

由 坚强是说给别人听的谎言 提交于 2019-12-07 04:38:21
Does anyone know of a free (for a non-profit group) RDLC reporting tool that will work under medium trust in IIS 7? Our Data Dynamics Reports product is not free, but we did implement special support for working in the restrictive medium trust environments. I don't know if it is tested on IIS7 yet, but I presume the security policy is the same so it should work in any case. If it does not let us know and we will surely get it working as this is a scenario we explicitly wanted to make sure that we provide a great solution for. For more information see the following links: Brief information

Anonymous type in medium trust, works with Reflection not with Expressions

问题 I'm doing custom projections on Linq queries in Medium Trust and I get a MethodAccessException or TypeAccessException complaining about reflection and security rights.

问题 I have a scenario where users of my ASP.NET web application submit testimonials consisting of text info and images. The submit process has the following steps: First the user inputs the content and chooses a path to an image When he clicks preview, the info is once again shown so that he can confirm Once confirmed the info is persisted in the database The problem with this is that I don't want to store uploaded images in the DB before the user actually confirms. Instead I store them as
