Question

我目前正在开发一个测试asp.net页面，该页面将在服务器上运行PowerShell脚本。

PowerShell脚本检查我存储在变量$ userinput中的用户输入是否与变量$ name匹配。

我已经设法从asp.net页面获取变量到PowerShell脚本。 Default.aspx.cs脚本在 userinput 上查找并替换，然后将脚本保存为修改版本。

我想在asp.net页面上打印出来自PowerShell脚本的变量$ result。我在asp.net页面上定义了一个名为Output的输出标签。

但是，在运行时，标签不会显示变量$ result。

Test.ps1

$name = "test"
$userinput = "*userinput*"


if(($userinput) -eq $name)
    {

    $result = "Name $userinput already taken!" 

    }
    else
    { 

     $result = "Name $userinput availble!" 

    }
