Java TreeMap equivalent in C#?

試著忘記壹切 提交于 2019-12-03 10:38:14
Most places I've consulted say to use SortedList, but the problem is that the program I'm porting actually uses duplicate keys (differentiated by order), which is permissible with TreeMap, but not SortedList. Any advice? Does SortedDictionary class help? Another great implementation of a Red Black Tree in .NET can be found here: http://www.itu.dk/research/c5/ I don't think C# has one natively. However there are plenty of examples of Red-Black implementations out there. Here is one:- http://www.codeproject.com/KB/recipes/redblackcs.aspx 来源: https://stackoverflow.com/questions/477954/java

PHP developer looking for solutions equivalent to Java EE architecture

问题 I am a PHP developer, I read about Java EE technologies and I want to implement such technologies( n-tier, EJB, JPA...) with PHP and all what coming with (MySQL, Apache...). 回答1: Don't. PHP is not Java. Writing PHP code like you'd write Java code is silly and counterproductive. It's very likely to make future maintainers of the code want to hurt you. Need to persist an object? Use an ORM. Need a multi-tier architecture? If you design your code with proper separation of concerns, you've

PHP is not Java. Writing PHP code like you'd write Java code is silly and counterproductive. It's very likely to make future maintainers of the code want to hurt you. Need to persist an object? Use an ORM . Need a multi-tier architecture? If you design your code with proper separation of concerns, you've already gotten 9/10ths of the way there. EJBs? Every time I read the Wikipedia article, they're described

孤街浪徒 提交于 2019-12-01 22:08:20
问题 I have a tables contains null values. In ORDER table i have 2 null in PART_ID section and 2 null values in CUSTOMER_ID. And i have that kind of query: SELECT O.ORDER_ID , O.ORDER_DATE , O.CUST_ID, O.QUANTITY ,O.PART_ID , C.CUST_NAME, C.CUST_CODE, P.PART_NAME, P.PART_CODE FROM [ORDER] O LEFT OUTER JOIN PART P ON P.PART_ID = O.PART_ID LEFT OUTER JOIN CUSTOMER C ON C.CUST_ID = O.CUST_ID So here is my question. How can i do it without using outer join ? I tried too many things including where not

Is there anything like /proc for windows [closed]

浪尽此生 提交于 2019-12-01 17:22:55
I'm Curious about 2 things, What is the closest equivalent to /proc that ships with windows Are there any products which add a proc like filesystem to windows? Task manager Cygwin , giving Windows a Linux environment, certainly allows a Windows program to use /proc . Grim It would help if you explained what your final goal is. What are you trying to do? For managing processes on windows you have the following options: Windows ships with Task Manager (taskmgr.exe) A better more versatile alternative is a tool called Process Explorer You also have the command line utility called tasklist.exe

DATEADD equivalent in PostgreSQL [duplicate]

血红的双手。 提交于 2019-12-01 14:54:02
问题 This question already has answers here : Postgres INTERVAL using value from table (3 answers) Closed 5 years ago . Is there an equivalent to this T-SQL command in PostgreSQL? select dateadd(hh,duration_in_hours,start_date) as end_date I have found only interval keyword with subsequent string, but this terrible construction returns syntax error: select start_date + interval cast(duration_in_hours as varchar) || ' hours' It allows only string constant after "interval " keyword. I am sure there

java.util.zip.deflater equivalent in c#

血红的双手。 提交于 2019-12-01 08:12:28
does anyone know how can I achieve java's Deflater.deflate() functionality in .NET so it would be understandable for java's Infalter.inflate() method? regards, Rafal I have used #zipLib . It is pretty straight forward. Taken from their site: #ziplib (SharpZipLib, formerly NZipLib) is a Zip, GZip, Tar and BZip2 library written entirely in C# for the .NET platform. It is implemented as an assembly (installable in the GAC), and thus can easily be incorporated into other projects (in any .NET language). The creator of #ziplib put it this way: "I've ported the zip library over to C# because I

MySQL DB selects records with and without umlauts. e.g: '.. where something = FÖÖ'

My Table collation is "utf8_general_ci". If i run a query like: SELECT * FROM mytable WHERE myfield = "FÖÖ" i get results where: ... myfield = "FÖÖ" ... myfield = "FOO" is this the default for "utf8_general_ci"? What collation should i use to only get records where myfield = "FÖÖ"? Gunni SELECT * FROM table WHERE some_field LIKE ('%ö%' COLLATE utf8_bin) A list of the collations offered by MySQL for Unicode character sets can be found here: http://dev.mysql.com/doc/refman/5.0/en/charset-unicode-sets.html If you want to go all-out and require strings to be absolutely identical in order to test

.NET code execution at normal process exit?

孤人 提交于 2019-11-30 20:29:05
In C there is the atexit function, which The atexit() function registers the given function to be called at normal process termination, either via exit(3) or via return from the program's main(). Python has a similar capability. Does .NET provide a way to call code at normal process termination? I know there are certain things like DomainUnload and ProcessExit , but at least as far as I can tell, these are unreliable - either requiring the application to be a Windows Forms (or WPF app), or something else. I am writing code for a .dll, so I can't rely on things like mucking with the main
