if (statement1) { # 执行语句1 } elseif (statement2) { # 执行语句2 } else { # 执行其他操作 } 在这个例子中,statement1和statement2是两个逻辑表达式,可以是任何返回布尔值的表达式。根据这两个语句的结果,程序将执行相应的代码块。 以下是对问题中提到的一些关键术语和概念的解释: 前端开发:前端开发涉...
如果 <test1> 和<test2> 的计算结果为 false,则 <statement list 3> 代码块将运行,并且 PowerShell 将退出 if 语句。 可以使用多个 elseif 语句链接一系列条件测试。 仅当以前的所有测试均为 false 时,才会运行每个测试。 如果需要创建包含许多 elseif 语句的 if 语句,请考虑改用 Switch 语句。 示例: 最...
Simple IF, Else$a = "Powershell" IF ($a -eq "PowerShell") { "Statement is True" } ELSE { "Statement is False" }You can condence this to:$a = "Powershell" IF ($a -eq "PowerShell"){ "Statement is True"} ELSE { "Statement is False"}...

else had signed it, my public key wouldn't be able to decrypt the signature. Once the signature is decrypted, Windows PowerShell compares the script to the copy that had been encrypted into the signature. If they match, then the signature is considered intact. If the two scripts differ, ...
Of course, if a malicious user were able to get a certificate for someone else's identity—say, from a CA that didn't have a good identity-checking process—you wouldn't be able to use the signature to identify the actual culprit. This is why the root CAs you trust should have an ...
