C# Windows应用调用PowerShell时如何正确传递布尔参数？

原本用于调用PowerShell脚本的C# Windows启动应用运行正常，但添加一个非必填布尔参数后，无论传递布尔值、$True/$true字符串还是整数1，调用都无法正常工作。

原有正常代码 #

var ps1File = @"DBScripter.ps1";
var ticketname = this.txtTicketName.Text;
var startInfo = new ProcessStartInfo()
{
    FileName = "powershell.exe",
    Arguments = $"-NoProfile -ExecutionPolicy unrestricted -file \"{ps1File}\" -TicketName \"{ticketname}\"",
    UseShellExecute = false
};
Process.Start(startInfo);

添加布尔参数后的异常代码 #

var ps1File = @"DBScripter.ps1";
var ticketname = this.txtTicketName.Text;
bool release = true;
var startInfo = new ProcessStartInfo()
{
    FileName = "powershell.exe",
    Arguments = $"-NoProfile -ExecutionPolicy unrestricted -file \"{ps1File}\" -TicketName \"{ticketname}\" -IsProdRelease \"{release}\"",
    UseShellExecute = false
};
Process.Start(startInfo);

PowerShell脚本参数声明 #

param (
    [Parameter(Mandatory = $false)]
    [string]$TicketName,
    [Parameter(Mandatory = $false)]
    [string]$TicketPath,
    [Parameter(Mandatory = $false)]
    [boolean]$IsProdRelease
)

方法1：使用-File时传递PowerShell原生布尔字面量 #

核心是不给布尔参数加引号，直接传入PowerShell识别的$true或$false字面量：

var ps1File = @"DBScripter.ps1";
var ticketname = this.txtTicketName.Text;
bool release = true;
var startInfo = new ProcessStartInfo()
{
    FileName = "powershell.exe",
    Arguments = $"-NoProfile -ExecutionPolicy unrestricted -file \"{ps1File}\" -TicketName \"{ticketname}\" -IsProdRelease {(release ? "$true" : "$false")}",
    UseShellExecute = false
};
Process.Start(startInfo);

原理：-File模式下参数按字面量解析，未加引号的$true/$false会被PowerShell直接识别为布尔类型，匹配脚本中[boolean]类型的参数声明。

方法2：改用-Command参数调用（更灵活） #

如果参数存在特殊字符或类型转换需求，用-Command模式可以更可靠地传递参数：

var ps1File = @"DBScripter.ps1";
var ticketname = this.txtTicketName.Text;
bool release = true;
var startInfo = new ProcessStartInfo()
{
    FileName = "powershell.exe",
    Arguments = $"-NoProfile -ExecutionPolicy unrestricted -Command & \"{ps1File}\" -TicketName \"{ticketname}\" -IsProdRelease {release.ToString().ToLower()}",
    UseShellExecute = false
};
Process.Start(startInfo);

原理：-Command模式下，传递小写的true/false字符串，PowerShell会自动将其转换为布尔类型；&用于正确调用脚本文件，确保参数绑定逻辑正常。
