如何调用 Powershell 脚本并从 C# windows 表单传递参数

Question

我想调用 powershell 脚本，它接受来自 c# windows 表单的一些参数。

例如：- 我有 powershell 脚本，它接受 2 个参数，我有一个 windows 表单，带有两个文本框和一个提交按钮。 我想从这两个文本框中将参数传递给 powershell 脚本。 当我按下提交按钮时，它将调用 powershell 脚本并在 powershell 终端上运行它，并在 powershell 终端上显示结果。

这是 powershell 脚本的工作示例，它为您提供 char 的 ASCII 代码。 假设您有 richTextbox1 用于显示脚本的 output 并且您有 button1 触发它运行 - 这是代码：

        public void RunPowershell()
        {
            var ps1File = @"C:\asc.ps1";

            ProcessStartInfo startInfo = new ProcessStartInfo();
            startInfo.FileName = @"powershell.exe";
            startInfo.Arguments = $@"& '{ps1File}' f";
            startInfo.RedirectStandardOutput = true;
            startInfo.RedirectStandardError = true;
            startInfo.UseShellExecute = false;
            startInfo.CreateNoWindow = true;
            Process process = new Process();
            process.StartInfo = startInfo;
            process.Start();

            string output = process.StandardOutput.ReadToEnd();
            string errors = process.StandardError.ReadToEnd();

            richTextBox1.Text = $"Output: {output}{Environment.NewLine}Errors = {errors}";
        }

        private void button1_Click(object sender, EventArgs e)
        {
            RunPowershell();
        }

这将为 char 'f' 提供 ascii 代码。

Bellow 是附在示例中的 PS 脚本：

function Syntax {
    Write-Host
    Write-Host "Asc.ps1,  Version 1.00"
    Write-Host "Returns the numeric ASCII value for the specified character"
    Write-Host
    Write-Host "Usage:   " -NoNewline
    Write-Host "ASC.PS1  char" -ForegroundColor White
    Write-Host
    Write-Host "Returns: Numeric ASCII value of " -NoNewline
    Write-Host "char" -ForegroundColor White
    Write-Host
    Write-Host "Notes:   The ASCII value is written to Standard Output (usually the screen)"
    Write-Host "         as well as returned as `"errorlevel`""
    Write-Host "         If more than 1 character is passed on the command line, only the first"
    Write-Host "         character will be used, the remainder of the string will be ignored."
    Write-Host "         The `"errorlevel`" will equal the ASCII value, or 0 if no parameter"
    Write-Host "         was passed, or -1 in case of errors or for this help"
    Write-Host
    Write-Host "Credits: Code to pass exit code as `"errorlevel`" to the calling batch file"
    Write-Host "         or PowerShell script by Serge van den Oever:"
    Write-Host "         weblogs.asp.net/soever/returning-an-exit-code-from-a-powershell-script" -ForegroundColor DarkGray
    Write-Host
    Write-Host "Written by Rob van der Woude"
    Write-Host "http://www.robvanderwoude.com"

    $Host.SetShouldExit( -1 )
    Exit
}

if ( $args.Length -eq 1 ) {
    if ( $args[0] -eq "/?" ) {
        Syntax
    } else {
        $input = $args[0]
    }
} else {
    Syntax
}

if ( $input -eq "" ) { $input = [string][char]0 }

[char]$char = $input[0]

Write-Host ([byte]$char) -NoNewline

# Pass exit code to calling batch or PowerShell script, by Serge van den Oever
# https://weblogs.asp.net/soever/returning-an-exit-code-from-a-powershell-script
$Host.SetShouldExit( [byte]$char )
Exit

将其保存到磁盘C ，将其命名为asc.ps1 --> 你就有了工作示例。

只需启动带参数的 powershell.exe

要启动任何外部应用程序，您可能需要检查 Process 的工作方式。
