When you use positional parameters, type one or more values after the function name. Positional parameter values are assigned to the$argsarray variable. The value that follows the function name is assigned to the first position in the$argsarray,$args[0]. ...
有关 PowerShell 常用参数的详细信息,请参阅 about_CommonParameters。 从PowerShell 3.0 开始,可以使用 splatting 和 @Args 来表示命令中的参数。 Splatting 在简单和高级函数上有效。 有关详细信息,请参阅 about_Functions 和about_Splatting。 参数值的类型转换 将字符串作为参数提供给需要不同类型...
Turning a function in PowerShell into an advanced function is really simple. One of the differences between a function and an advanced function is that advanced functions have a number of common parameters that are added to the function automatically. These common parameters include parameters such ...
Positional parameters allow you to provide a value without specifying the name of the parameter. When using a parameter positionally, you must specify its value in the correct position on the command line. You can find the positional information for a parameter in the PARAMETERS section of a ...
Use the full name of all cmdlets and parameters unless you're specifically documenting the alias. Cmdlet and parameter names must use the proper Pascal-cased names.Using parameters in examplesAvoid using positional parameters. In general, you should always include the parameter name in an example,...
Understanding positional parameters Positional parameters make Windows PowerShell commands shorter because you do not have to do as much typing, and some of the parameter names are rather long. But the problem is that unless you really know what a cmdlet does, and how it does it, you might ...
The real difference between a mere function and a full cmdlet is that cmdlets support powerful parameter bindings. You can use positional parameters, named parameters, mandatory parameters, and even do basic parameter validation checks—all by simply describing the parameter to the shell. Here’s an...

Use positional parameters and make parameters mandatory when it makes sense to do so. For example, I'm looking for something like the following: [Parameter(Position = 0, Mandatory = $True)] Don't use any aliases unless it makes sense for receiving pipeline input. They make code more diff...
Bind positional parameters. Bind common parameters. Bind parameters to support calls toShouldProcess. Bind dynamic parameters, first the named ones, and then the positional ones. During the first binding phase, the pipeline processor uses the metadata for the parameters, the type definitions of the...
