有一段代码,想用C#来表示,主要是数组问题

Jun 23, 2016 pm 02:00 PM

$cursor = exequery( TD::conn( ), $query );while ( $rows = mysql_fetch_array( $cursor ) ){	$a_bi[$tid]['selected'] = array( );	$a_bi[$tid]['unselected'] = array( );}
Copy after login

$cursor = exequery( TD::conn( ), $query );while ( $rows = mysql_fetch_array( $cursor ) ){	$tid = $rows['tid'];	$rid = $rows['rid'];	$report_name = $rows['report_name'];	$report_limit_users = $rows['report_limit_users'];	$s_type_name = "[".$a_bi[$tid]['name']."]";	if ( strpos( $report_limit_users, $s_user ) === FALSE )	{		$a_report[$rid]['name'] = $s_type_name.$report_name;		$a_bi[$tid]['selected'][$rid]['name'] = $s_type_name.$report_name;	}	else	{		$a_bi[$tid]['unselected'][$rid]['name'] = $s_type_name.$report_name;	}}

主要是数组怎么用C#语法表示。听说用字典可以,但还是不知道怎么写。

C# 不也是支持多维数组的吗?
你把键名换成下标不就可以了吗?

具体怎么写呢,给个例子吧

比如 $a_bi[$tid]['selected'][$rid]['name'] 
可写作
a_bi[tid][selected][rid][name] 
其中 tid 和 rid 是读取的变量 selected 和 name 是自定义变量,取值 0,1,2,3,4....

这样的直译的好处在于没有改变原算法的形式,也不需要完全理解算法原理
坏处在于无效的内存较多,但可在理解算法的基础上进行优化。当然这是后话了

在PHP中这是个多维数组吧?如果按C#来这样写的话,估计会报错吧,C#中ARRAYLIST一维可以用索引,如果多维的话也可以吗?

Dictionary>
a_bi = new 
Dictionary>如果是字典对象,这样写对不对?

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
