jgr*_*012 2 powershell exception return-value
是否有可能捕获由函数创建的输出,这也会导致异常?
function functionWhichCreatesOutputThenCausesAnException() {
"hello"
1/0
"world"
}
try {
$result = functionWhichCreatesOutputThenCausesAnException
} catch {
$($error[0])
}

我的功能创建的输出显示在我的终端中.我想捕捉"你好".这可能吗?
这似乎有效:
function functionWhichCreatesOutputThenCausesAnException() {
"hello"
1/0
"world"
}
try {
$result = @()
functionWhichCreatesOutputThenCausesAnException | foreach {$result += $_}
} catch {
$($error[0])
}
