问题 I want to use DataTable class on iOS. I am implementing DataTable class as you see in the code. It works fine on Android and Standalone builds with Unity. I cannot figure it out why iOS is not woking. The interesting part is the early version of this app works fine on all platforms. Is there any idea how to dig in to the issue? I check the build folder on Xcode and I see the System.Data.dll on the resources folder so the is no optimization stripped all necessary files are included. DataTable

问题 I'm trying to recursively create a bunch of directories and certain directory names have ':' characters in which throws the above exception. I was hoping there may be a way to avoid this? Below is a snip of the code I'm using: foreach (TagLib.File tagFile in tagFiles) { GetInfo(tagFile, targetDir); if (!Directory.Exists(TargetFullPath)) { Directory.CreateDirectory(TargetFullPath); System.IO.File.Copy(FilePath, TargetFullPath + "\\" + tagFile.Tag.Title + TargetExt); } ...

问题 Edit: Updated problem description based on testing - 12 Sep 2011. I have this query that throws a NotSupportedException ("Specified method is not supported.") whenever I call .ToList(). IQueryable<FileDefinition> query = db .FileDefinitions .Include(x => x.DefinitionChangeLogs) .Include(x => x.FieldDefinitions.Select(y => y.DefinitionChangeLogs)) // bad .Include(x => x.FieldDefinitions.Select(y => y.FieldValidationTables)) // bad .Where(x => x.IsActive); List<FileDefinition> retval = query

问题 I’ve got an ASP.NET MVC project which I haven't worked on in almost two months. Debugging in a browser works fine as long as I don’t change ANY code. The moment I modify any code whatsoever, even adding whitespace, I get this error: An exception of type 'System.NotSupportedException' occurred in EntityFramework.dll but was not handled in user code Additional information: The type 'System.Web.Routing.RouteCollection+IgnoreRouteInternal' and the type 'System.Web.Mvc.RouteCollectionExtensions

问题 I've got a problem with NotSupportedException, I'm getting: "An attempt has been made to Attach or Add an entity that is not new, perhaps having been loaded from another DataContext." partial class SupplyOfert : Model { public SupplyOfert(int id = 0) { if (id > 0) this.get(id); } public Supplier supplier { get { return this.Supplier; } set { this.Supplier = db.Suppliers.SingleOrDefault(s => s.id == value.id); } } public override bool get(int id) { SupplyOfert so = (SupplyOfert)db.SupplyOferts

问题 I am using two different third party programs (different companies) that apparently use the Google Maps Javascript API.

Verwenden Sie einen anderen Browser". (Translation: The browser you are using is not supported by Google Maps Javascript API. Use another browser). I am using Windows 7 and Internet Explorer 11.0.48.

问题 I'am trying to store a value of Document.cookie into a string variable in my c# code. The idea here is to go through each tab in an Internet Explorer browser and then get the cookie information from the tab. So I have got the following, ShellWindows iExplorerInstances = new ShellWindows(); bool found = false; foreach (InternetExplorer iExplorer in iExplorerInstances) { if (iExplorer.Name == "Internet Explorer") { string cookie = iExplorer.Document.cookie; Now this works upon initial running

问题 I'm having some trouble with finding the right syntax to accomplish the following: Is it possible with LINQ (Lambda Expression) to .GroupBy data and instead of using the usual .Sum() or .Count() I want the resulting data to be a List of Int. I defined my own class named: Filter_IDs. Its constructor needs two parameters: public int? type; // Represents the object_type column from my database public List<int?> objects; // Represents the object_id column from my database I want to load data from
