[英]How to pass parameters to a powershell script using c# winforms?
I want to execute a powershell script via winforms and get well-formatted output.我想通过 winforms 执行 powershell 脚本并获得格式良好的输出。 I managed to get it to work but now I need to pass parameters to my script.我设法让它工作,但现在我需要将参数传递给我的脚本。 I can't manage to make that happen.我无法做到这一点。
Here is my RunScript function :这是我的 RunScript 函数:
private string RunScript(string scriptFile)
{
Runspace runSpace = RunspaceFactory.CreateRunspace();
runSpace.Open();
Pipeline pipeLine = runSpace.CreatePipeline();
Command script = new Command(scriptFile);
script.Parameters.Add("COM_USERNAME", usernameBox.Text);
script.Parameters.Add("COM_PASSWORD", passwordBox.Text);
script.Parameters.Add("installDir", installDirBox.Text);
script.Parameters.Add("TEMPVAULT_PATH", tempVaultBox.Text);
script.Parameters.Add("MAX_REQ_LIMIT", maxReqLimBox.Text);
script.Parameters.Add("MAX_BUFF_LIMIT", maxBuffLimBox.Text);
pipeLine.Commands.AddScript(script.ToString());
pipeLine.Commands.Add("Out-String");
Collection<PSObject> results = pipeLine.Invoke();
runSpace.Close();
StringBuilder strBuilder = new StringBuilder();
foreach (PSObject item in results)
{
strBuilder.AppendLine(item.ToString());
}
return strBuilder.ToString();
}
And this is the script that I am trying with:这是我正在尝试的脚本:
param (
[bool] $STARTSERVICE = $false ,
[bool] $INSTALL = $false ,
[bool] $INSTALL_DASHBOARD = $false,
[bool] $DASHBOARD_SETTINGS = $false,
[bool] $DASHBOARD_CREATENEWDB = $false,
[bool] $DALIM_SETTINGS = $false,
[bool] $INSTALLIIS = $true,
[bool] $FIRST_INSTALL = $true,
[bool] $RECOVERY = $false,
[string] $COM_USERNAME,
[string] $COM_PASSWORD,
[string] $RECOVERY_ADM_NAME,
[string] $RECOVERY_ADM_PWD,
[string] $Windows2012DVDLetter = "F:",
[string] $COM_UNCPATH,
[string] $installDir = "C:\Program Files\App\",
[string] $TEMPVAULT_PATH = "C:\TempVault",
$SOAP_MaxPostSize = 4294967295,
$MAX_REQ_LIMIT = 500000000,
$MAX_BUFF_LIMIT = 500000000
)
Write-Output "`nUsername = " $COM_USERNAME
Write-Output "`nPassword = " $COM_PASSWORD
Write-Output "`nCOM_UNCPATH = " $COM_UNCPATH
Write-Output "`nMaximum Request Limit = " $MAX_REQ_LIMIT
Write-Output "`nMaximum Buff Limit = " $MAX_BUFF_LIMIT
Write-Output "`nIsFirstInstall = " $FIRST_INSTALL
Write-Output "`nInstallation Directory = " $installDir
Write-Output "`nTempVault Path = " $TEMPVAULT_PATH
Write-Output "`nRestriction level = " $RESTRICT_LVL
I have output with only the pre-registered in the script values showing, but the ones I'm trying to show (textboxes inputs) don't.我的输出仅显示脚本值中预先注册的值,但我尝试显示的值(文本框输入)没有。 Have I missed something?我错过了什么吗?
Note: The following assumes that scriptFile
is the path of a *.ps1
file, not that file's content (a string containing Powershell code).注意:以下假设scriptFile
是*.ps1
文件的路径,而不是该文件的内容(包含 Powershell 代码的字符串)。
See the bottom section for how to handle the latter case.有关如何处理后一种情况,请参阅底部部分。
You can greatly simplify your invocation :您可以大大简化您的调用:
private string RunScript(string scriptFile)
{
using (var ps = PowerShell.Create()) {
ps.AddCommand(scriptFile) // Be sure to pass a *full path*
.AddParameter("COM_USERNAME", usernameBox.Text)
.AddParameter("COM_PASSWORD", passwordBox.Text)
.AddParameter("installDir", installDirBox.Text)
.AddParameter("TEMPVAULT_PATH", tempVaultBox.Text)
.AddParameter("MAX_REQ_LIMIT", maxReqLimBox.Text)
.AddParameter("MAX_BUFF_LIMIT", maxBuffLimBox.Text)
.AddCommand('Out-String'); // Add a pipeline segment
// Return the 1st (and in this case only) output object, as a string.
return ps.Invoke<string>()[0];
}
}
Using PowerShell.Create()
creates an instance of class PowerShell
, which provides a higher-level API based on an implicitly created runspace:使用PowerShell.Create()
创建类PowerShell
的实例,它提供基于隐式创建的运行空间的更高级别的 API :
.AddCommand()
repeatedly automatically adds new pipeline segments.重复调用.AddCommand()
自动添加新的管道段。As for what you tried :至于你尝试了什么:
pipeLine.Commands.AddScript(script.ToString());
The .AddScript()
method is for adding arbitrary pieces of PowerShell code , not for adding Command
instances with associated parameters. .AddScript()
方法用于添加任意的PowerShell 代码片段,而不是用于添加具有关联参数的Command
实例。
( Command
instances represent either a PowerShell command such as Out-String
or the name / path of an external executable or the path [1] to a script file ( *.ps1
)). ( Command
实例表示 PowerShell 命令,例如Out-String
或外部可执行文件的名称/路径或脚本文件 ( *.ps1
) 的路径[1] )。
By stringifying the Command
instance stored in script
with .ToString()
, you're effectively just passing the script path as the command to execute - all the parameters you've added with .AddParameter()
are lost, which is why you only saw the default parameter values in the script's output.通过使用.ToString()
存储在script
的Command
实例进行字符串化,您实际上只是将脚本路径作为要执行的命令传递 - 您使用.AddParameter()
添加的所有参数都将丢失,这就是为什么您只看到脚本输出中的默认参数值。
Instead, you should have added your Command
instance as follows :相反,您应该按如下方式添加您的Command
实例:
pipeLine.Commands.Add(script)
If scriptFile
is not a file path , but the contents of a script file (a string containing PowerShell code):如果scriptFile
不是文件路径,而是脚本文件的内容(包含 PowerShell 代码的字符串):
As you've since clarified, this is your actual use case, because the script is embedded as a resource in your executable that you pass with RunScript(Properties.Resources.<the script>)
正如您已经澄清的那样,这是您的实际用例,因为脚本作为资源嵌入到您通过RunScript(Properties.Resources.<the script>)
传递的可执行文件中
Adapt the simplified approach at the top as follows:调整顶部的简化方法如下:
// If `scriptFile` is the *contents* of a *.ps1 file,
// add it as a script [block] with .AddScript(),
// then add parameters (and the additional pipeline command).
ps.AddScript(scriptFile)
.AddParameter("COM_USERNAME", usernameBox.Text)
.AddParameter("COM_PASSWORD", passwordBox.Text)
.AddParameter("installDir", installDirBox.Text)
.AddParameter("TEMPVAULT_PATH", tempVaultBox.Text)
.AddParameter("MAX_REQ_LIMIT", maxReqLimBox.Text)
.AddParameter("MAX_BUFF_LIMIT", maxBuffLimBox.Text)
.AddCommand('Out-String'); // Add a pipeline segment
[1] PowerShell only allows by-name-only executions (eg, foo.ps1
) for executables / scripts located in a directory listed in the PATH
environment variable. [1] PowerShell 只允许对位于PATH
环境变量中列出的目录中的可执行文件/脚本执行仅按名称执行(例如, foo.ps1
)。 Otherwise, a file path must be specified, and it's safest to use a full path , because .NET's current directory usually differs from PowerShell's.否则,必须指定文件路径,使用完整路径最安全,因为 .NET 的当前目录通常与 PowerShell 的不同。
