.net-4.0

问题 We have custom DLL's that are not included in our initial setup file. They are loaded at runtime. This process worked fine while using .NET 2.0, but we are getting the "The invoked member is not supported in a dynamic assembly" error message now that we are using .NET 4.0. try { assem = Assembly.LoadFrom(fi.FullName); //fi is FileSystemInfo } catch (FileLoadException) {} catch (BadImageFormatException) {} catch (System.Security.SecurityException) {} catch (ArgumentException) {} catch

问题 I'm thinking about using Awesomium.NET for a project I'm working on which is built with .NET 4.5. Awesomium.NET targets the .NET 4.0 Client Profile. Will it be OK to reference the 4.0 libraries from a 4.5 project? 回答1: That should be fine, both .Net 4.0 and .Net 4.5 use CLR 4. 回答2: In general, assemblies compiled in .NET 1.1 or later can be referenced in higher runtime (CLR) versions. However, you cannot reference an assembly compiled in 4.0 in runtime 3.0 来源： https://stackoverflow.com

问题 I'm computing the area of a rectagle after exclude the area of some circles. this is my current solution: var region = new Region( new Rectangle(0, 0, 10, 10) ); var circle = new System.Drawing.Drawing2D.GraphicsPath(); circle.AddEllipse(50, 50, 25, 25); // Exclude the circle from the region. region.Exclude(circle); However I need something like region.getArea() to get the area after excluding the circle. Do you know how to compute a System.Drawing.Region area? -Or- Do you know another way to

问题 Code snippet is as follows public static string ToCompressedBase64(this string text) { using (var memoryStream = new MemoryStream()) { using (var gZipOutputStream = new GZipStream(memoryStream, CompressionMode.Compress)) { using (var streamWriter = new StreamWriter(gZipOutputStream)) { streamWriter.Write(text); } } return Convert.ToBase64String(memoryStream.ToArray()); } } As far as I know, if class contains field which is IDisposable then It should implement IDisposable itself and take care

问题 I've got an interesting situation where locale settings has messed with my C# application, because I failed to realize that methods like Double.Parse will not convert "1000" to 1000, but do something unexpected due to the different numbering format. One solution to my problem would be to use something like double d = double.parse( "1000", new CultureInfo("en-US")); . Currently, I don't pass the CultureInfo. However, instead of having to make this change throughout the code, I was wondering if

问题 I am trying to add a reference to a .Net 2.0 DLL in a WPF application that is targeted to the .Net 4 Framework. I added <startup useLegacyV2RuntimeActivationPolicy="true"> to the app.config file. The WPF app builds fine, but gets a BadImageFormatException at Runtime when trying to access the .Net 2.0 DLL. "An attempt was made to load a program with an incorrect format" This works with a new test WPF project, but does not work on my app. My app uses Entity Framework and MEF. Could these
