问题 I'm trying to figure out how I can pass multiple strings as an array to a powershell function. function ArrayCount([string[]] $args) { Write-Host $args.Count } ArrayCount "1" "2" "3" ArrayCount "1","2","3" ArrayCount @("1","2","3") Prints 2 0 0 How can I pass an array with 3 values to the ArrayCount function? Why is the Count zero for some of the invocations? 回答1: In PowerShell, $args is a automatic variable that refers to unnamed arguments. Just change your parameter name: function

问题 I inherited a database loaded into DocumentDB, where field name happens to be "Value". Example of my structure is: { ... "Alternates": [ "Type": "ID", "Value" : "NOCALL" ] } when I query (using documentDB's SQL), trying to get back all documents where Alternates.Value = "NOCALL", I get syntax error near "Value" error . If I query for Type = "ID", it is all fine. Seems that the word Value, having a special meaning on DocumentDB is causing an issue. Putting punctuation (e.g. quotes/double

问题 I need a list of Oracle Database 10g and SQL Server 2008 reserved key words. My application performs DDL statements, thus I need to validate the entered table-, column names, etc. against the reserved words. I know that I can copy and paste the words from the websites: Oracle 10g and SQL Server 2008 But I would prefer a SQL command so that the keywords can be loaded dynamically. For oracle there exists the command: SELECT KEYWORD FROM V$RESERVED_WORDS ORDER BY KEYWORD ASC ; It's just strange

问题 I'm using MSBuild to customize the build process of Visual Studio, WiX, SandCastle, ... projects. To keep it as generic as possible I'd like to use text files defining some 'project specific' settings, like where the files should be loaded from, which custom executables to run and so on. A text file could look like this: $(MSBuildProjectDirectory)....\Projects\Project1\bin\Release obj\$(Configuration)\Project1.Files.wxi -in *.dll -id TEST Each line represents one command or file. Inside my

问题 I'd like to create a function called "new" and a class called "case". Can I do that in PHP? 回答1: No, you can't. Thank god. 回答2: Actually, while defining such a method results in a parse error, using it does not, which allows some kind of workarounds: class A { function __call($method, $args) { if ($method == 'new') { // ... } } } $a = new A; $a->new(); // works! A related feature request dating back to 2004 is still open. Edit January 2016 As of PHP 7, it is now possible to name your methods

问题 any help appreciated: I'm a bit confused with the fact that when I add a reserved IP to a cloud service, the IP address matches the one reserved. When I do the same but add an instance IP address to a certain machine, it only adds a random public IP address to the machine, and changes the name accordingly to the one reserved but the IP address does not matches the one reserved. Any ideas? This is my reserved IP ReservedIPName : name Address : XX.XX.11.119 Id : AA Label : sipserver Location :

问题 This is my first post and I absolutely <3 this site! So much great content! So, I have the following TCPDump command I want to understand what it is asking (in plain English). tcpdump 'tcp[12] & 80 !=0' Is it asking to grab all TCP packets on byte offset 12 (TCP Header length and Reserved bits) with values at least 80 that is true? I believe I am wrong. If the above is true, can someone write out the possible binaries for it? 80 gives 0101 0000. My mentor also wrote down: 1111 0000 and 0111

问题 In this page, Microsoft says that XML reserved characters (and their entity) are the following ones: > > < < & & % % But in this other page, I found that also ' is a reserved character (and its entity is &apos; ). Can someone indicate me some official reference in which are listed all and only the XML reserved characters? 回答1: According to the XML spec, the only characters that must be escaped when used as character content rather than markup are & (as & , & or & ) and < (as < , < or < ),
