Вот рабочий пример сценария PowerShell, который дает вам код ASCII для char. Предполагая, что у вас есть richTextbox1 для отображения вывода скрипта и что у вас есть кнопка 1, которую вы запускаете, - вот код:
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();
}
Это даст код ascii для char 'f'.
Ниже приведен сценарий PS, прикрепленный к примеру:
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
Сохраните его на диск C
, назовите его asc.ps1
->, и у вас есть рабочий пример.
