我正在自动化部署到azure云的过程。我的powershell脚本就是这样做的，当从azure powershell命令行执行它时，它就像一个魅力。当我尝试从c＃应用程序调用相同的脚本时，它失败了。
这是我的代码：
internal void RunPowerShellScript(string scriptPath, Dictionary<string, string> arguments)
{
RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
runspace.Open();
RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
Pipeline pipeline = runspace.CreatePipeline();
//Here's how you add a new script with arguments
Command myCommand = new Command(scriptPath, true);
foreach (var argument in arguments)
{
myCommand.Parameters.Add(new CommandParameter(argument.Key, argument.Value));
}
pipeline.Commands.Add(myCommand);
var results = pipeline.Invoke();
foreach (var psObject in results)
{
_view.PrintOutput(psObject.ToString());
}
}
我也跟着其他线程，就像这样：Execute PowerShell Script from C# with Commandline Arguments 这一个：passing parameters to powershell from c#
但似乎没有任何效果。我收到以下错误：
无法验证参数'PublishSettingsFile'的参数。参数为null或空。提供一个非null或空的参数，然后再次尝试该命令。

我相信您传递publishsettings文件的方式导致了问题。传递publishsettings文件时，必须添加引号，如果没有引号，则会触发异常。
以下是基于您的代码的代码，我通过使用（\“）使用引号传递publishsetting文件来测试它，它运行正常：
private void button1_Click(object sender, EventArgs e)
{
Dictionary<string, string> myDict= new Dictionary<string, string>();
myDict.Add("-subscriptionDataFile", "\"C:\\InstallBox\\asc.publishsettings\"");
RunPowerShellScript("C:\\InstallBox\\testcode.ps1", myDict);
}
internal void RunPowerShellScript(string scriptPath, Dictionary<string, string> arguments)
{
RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
runspace.Open();
RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace);
Pipeline pipeline = runspace.CreatePipeline();
//Here's how you add a new script with arguments
Command myCommand = new Command(scriptPath);
foreach (var argument in arguments)
{
myCommand.Parameters.Add(new CommandParameter(argument.Key, argument.Value));
}
pipeline.Commands.Add(myCommand);
var results = pipeline.Invoke();
foreach (var psObject in results)
{
.........
}
}
我的testcode.ps1如下：
Param( [string]$subscriptionDataFile)
Import-Module Azure
Import-AzurePublishSettingsFile subscriptionDataFile
Get-AzureSubscription
为了确保我能看到你的问题，如果我将字典键值对更改为如下（没有引号），我会得到完全相同的错误：
myDict.Add("-subscriptionDataFile", "C:\\InstallBox\\asc.publishsettings");
所以传递PublishSettings文件的正确方法如下：
myDict.Add("-subscriptionDataFile", "\"C:\\InstallBox\\asc.publishsettings\"");
