问题 I'm using EF 5.0 Code First, in a .NET 4 library. Trying to set a class member to be of an Enum type, but it doesn't get persisted to the database, and no runtime exception occurs when EF is creating the database based on the code. Of course, when I try to query against that Enum: var departments = db.Departments .Where(dep => dep.Name == DepartmentNames.English); I get an exception saying: The specified type member 'Name' is not supported in LINQ to Entities. Only initializers, entity

问题 I've been struggling with this problem for a couple days, and I still am not sure how to solve it. I've created a container extension for the Unity Container to enable me to easily register decorator classes in the container. This is the implementation I currently have, which is almost identical to the one in this article: public class DecoratorExtension : UnityContainerExtension { private int m_order; private Dictionary<Type, IList<DecoratorRegistration>> m_typeStacks; protected override

问题 The following LINQ reads a delimited file. Currently, it outputs only the recordId. I want it to output all the fields in file so I can perform some additional LINQ operations on the data. For example, I want to group by recordId, sort by a date, and take(x) results. I want all the fields in the csv to be returned. Do I need to decalre a variable and set use the index value, like I did for FirstName, LastName and recordId? Not a big deal but is there a better way? I tried removing the return

问题 I am creating long running workflow with will create a Bookmark for the persistance. When I execute the workflow it is workflow is working like a charm. Issue is here when I enclose the entire workflow in transaction scope, it is not completing its execution once it hits .waitone() I don't see the execution. For sure we need the transaction to be present out the workflow. I checked the DTC setting on the DB its ON. I think issue is with bookmarking in WF 4.0 and transaction on top of it. 回答1:

问题 I am working on a project and i have to check for some values of type short in a generic list of object. Strangely I noticed that it is always returning false even if there is that value in the generic list of objects. I am providing a small piece of code which replicates that scenario in my project. List<object> objectList = new List<object>(); objectList.Add(1); objectList.Add(2); objectList.Add(3); if (objectList.Contains(1)) { short i = 1; if (objectList.Contains(i)) { } else if

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 4 months ago . In the code below I try to send a set of notifications and I want to know if a notification was sent successfully (to put it in a database later so never send it again). Is it bad I'm catching Exception here? I really don't care about the reason a notification wasn't sent.

问题 I have a MVC 3 application that targets .net 4.0 It has a dozen or so projects also targeting .net 4.0 I have created a new project for the solution targeting .net 4.5 that uses reflection (there are a couple of nice bits of functionality in 4.5 that I want to use). When I try to compile I get an error saying that the 'type or namespace (new 4.5 proj) could not be found, are you missing a directive or an assembly reference'. Is it possible to have a reference to an assembly targeting .net 4.5

问题 We use the MojoPortal to a website and have some problems to upload files that is around 100 MB with the upload module. (Pleas note that this has probably nothing to do with MojoPortal but with the ASP.NET and the IIS) The MojoPortal is set to use regular file Upload(not Neat Uploader) and to be able to upload big files we have set the following : <httpRuntime maxRequestLength="2097151" executionTimeout="18000" requestValidationMode="2.0"/> And : <compilation debug="false" defaultLanguage="C#

问题 I am using the Knuth-Fisher-Yates algorithm to display a shuffled array of string items on a windows form. I do not get any duplicates, which is what I was trying to achieve, however, it only spits out 12 of the 13 elements of the array. How can I get it to display all 13 elements of the array? Here is my code: private void FormBlue1_Load(object sender, EventArgs e) { // set the forms borderstyle this.FormBorderStyle = FormBorderStyle.Fixed3D; // create array of stationOneParts to display on
