.net-4.0

问题 I have a long running method and I want to add timeout into it. Is it feasible to do that? Something like: AbortWaitSeconds(20) { this.LongRunningMethod(); } Where when it reached 20 seconds, the method will be aborted. The method doesn't have loop and I do not have a control/code over that method. 回答1: See my answer to this question for a generic solution. 回答2: try this class Program { static void Main(string[] args) { if (RunWithTimeout(LongRunningOperation, TimeSpan.FromMilliseconds(3000))

问题 This is similar to already created thread here: Mixed mode assembly in .NET 4 Using the app config, I was able to force the assemblies to run on .NET 4. On an XP Machine, I installed just the .NET 4 (without .NET 3.5 or 2.0) and tried to run the built application. It fails to load the mixed mode assembly built in 3.5 framework in .NET 4 without the .NET 3.5 framework on the machine. Why should it depend on .NET 3.5 when I am forcing the application to run on .NET 4 using App config? 回答1: You

问题 Is there any alternative to visual studio 2010 for develop with .net 4.0? thanks 回答1: Considering that .NET 4.0 only just came out (at the same time as VS 2010) I would hazard a guess at "No". :) In general, Visual Studio is by far the best IDE I've ever used. Nothing else even comes close. 回答2: You can use SharpDevelop to develop .NET projects, including .NET version 4.0. SharpDevelop 4.0 final has been released 06/2011. ( though the support for 4.0 is still in beta status AFAIK. ) 回答3:

问题 The title suggests that i've already an idea what's going on, but i cannot explain it. I've tried to order a List<string[]> dynamically by each "column", beginning with the first and ending with the minimum Length of all arrays. So in this sample it is 2 , because the last string[] has only two elements: List<string[]> someValues = new List<string[]>(); someValues.Add(new[] { "c", "3", "b" }); someValues.Add(new[] { "a", "1", "d" }); someValues.Add(new[] { "d", "4", "a" }); someValues.Add(new

问题 I was asked to build a mechanism for 3 retries before generating a request exception. We have this topology : Service1 calls Service2 . If 3 times in a row has failed - generate an excpetion. Is there any retry mechanism in WCF ? 回答1: The WCF technology addressing this is Reliable Messaging . I think MaxRetryCount is the attribute you are looking for. Here is an example with a custom binding using MaxRetryCount. 来源： https://stackoverflow.com/questions/13195959/wcf-3-retries-before-exception

问题 I have an SQL Server stored procedure that ressembles this: CREATE PROCEDURE [jp].[GetFoo] @Guid UNIQUEIDENTIFIER AS SELECT CONVERT(BIT, (CASE WHEN [dbo].[GetBar](T.Col2) = 3 THEN 1 ELSE 0 END)) IsGetBarCol2EqualToThree FROM [dbo].[MyTable] T WHERE T.Col1 = @Guid When I do Function Import / Get Column Information in EF, the inferred type of the column IsGetBarCol2EqualToThree is Nullable<bool> . But there is no way this field is going to be null, so I'd like it to be just bool . Is there a

问题 I have a run time exception after changing Target Framework to .net framework 4: A first chance exception of type 'System.BadImageFormatException' occurred in When building with target framework 3.5, everything works fine. The platform i am building to is x86 (i found out that building to x64 night cause the problem). What can be the problem? 回答1: MSDN lists possible reasons for this, so I'd suggest running through this as a checklist: An attempt is made to load an unmanaged dynamic link
