本文介绍了从 C# 应用程序运行 PowerShell 脚本的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试从 c# 应用程序执行 PowerShell 脚本.脚本必须在特殊的用户上下文下执行.
I'm trying to execute a PowerShell script from a c# application. The script has to be executed under a special usercontext.
我尝试了不同的场景，有些有效，有些无效:
I've tried different scenarios some are working some not:
1.从 PowerShell 直接调用
我直接从在正确的用户凭据下运行的 ps-console 调用了该脚本.
I've called the script directly from a ps-console which is running under the correct usercredentials.
C:ScriptsGroupNewGroup.ps1 1
结果:成功运行脚本.
2.来自 c# 控制台应用程序
我从在正确的用户凭据下启动的 c# 控制台应用程序调用了脚本.
I've called the script from a c# consoleapplication which is started under the correct usercredentials.
代码:
string cmdArg = "C:\Scripts\GroupNewGroup.ps1 1"
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.ApartmentState = System.Threading.ApartmentState.STA;
runspace.ThreadOptions = PSThreadOptions.UseCurrentThread;
runspace.Open();
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(cmdArg);
pipeline.Commands[0].MergeMyResults(PipelineResultTypes.Error, PipelineResultTypes.Output);
Collection<PSObject> results = pipeline.Invoke();
var error = pipeline.Error.ReadToEnd();
runspace.Close();
if (error.Count >= 1)
{
string errors = "";
foreach (var Error in error)
{
errors = errors + " " + Error.ToString();
}
}
结果: 没有成功.还有很多空数组"异常.
Result: No Success. And a lot of "Null-Array" exceptions.
3.来自 c# 控制台应用程序 - 代码端模拟
(http://platinumdogs.me/2008/10/30/net-c-impersonation-with-network-credentials)
我从 c# 控制台应用程序中调用了脚本，该应用程序在正确的用户凭据下启动，并且代码包含模拟.
I've called the script from a c# consoleapplication which is started under the correct usercredentials and the code contains impersonation.
代码:
using (new Impersonator("Administrator2", "domain", "testPW"))
{
using (RunspaceInvoke invoker = new RunspaceInvoke())
{
invoker.Invoke("Set-ExecutionPolicy Unrestricted");
}
string cmdArg = "C:\Scripts\GroupNewGroup.ps1 1";
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.ApartmentState = System.Threading.ApartmentState.STA;
runspace.ThreadOptions = PSThreadOptions.UseCurrentThread;
runspace.Open();
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(cmdArg);
pipeline.Commands[0].MergeMyResults(PipelineResultTypes.Error, PipelineResultTypes.Output);
Collection<PSObject> results = pipeline.Invoke();
var error = pipeline.Error.ReadToEnd();
runspace.Close();
if (error.Count >= 1)
{
string errors = "";
foreach (var Error in error)
{
errors = errors + " " + Error.ToString();
}
}
}
结果:
- 术语Get-Contact"未被识别为 cmdlet 的名称，函数、脚本文件或可运行的程序.检查拼写名称，或者如果包含路径，请验证路径是否正确并且再试一次.
- 术语C:ScriptsFunctionsObjects.ps1"未被识别为cmdlet、函数、脚本文件或可运行程序的名称.查看名称的拼写，或者如果包含路径，请验证路径正确，然后重试.
- 尚未为 Windows PowerShell 版本 2 注册任何管理单元.Microsoft.Office.Server，版本=14.0.0.0，文化=中性，PublicKeyToken=71e9bce111e9429c
- System.DirectoryServices.AccountManagement，版本=4.0.0.0，文化=中性，PublicKeyToken=b77a5c561934e089
- 使用1"个参数调用.ctor"的异常:Web 应用程序在
http://XXXX/websites/Test4/找不到.验证您是否已正确输入 URL.如果 URL 应该提供现有的内容，系统管理员可能需要添加新的请求 URL映射到预期的应用程序." - 不能对空值表达式调用方法.无法索引到一个空数组.
- The term 'Get-Contact' is not recognized as the name of a cmdlet,function, script file, or operable program. Check the spelling of thename, or if a path was included, verify that the path is correct andtry again.
- The term 'C:ScriptsFunctionsObjects.ps1' is not recognized as thename of a cmdlet, function, script file, or operable program. Checkthe spelling of the name, or if a path was included, verify that thepath is correct and try again.
- No snap-ins have been registered for Windows PowerShell version 2.Microsoft.Office.Server, Version=14.0.0.0, Culture=neutral,PublicKeyToken=71e9bce111e9429c
- System.DirectoryServices.AccountManagement, Version=4.0.0.0,Culture=neutral, PublicKeyToken=b77a5c561934e089
- Exception calling ".ctor" with "1" argument(s): "The Web applicationat
http://XXXX/websites/Test4/could not be found. Verify that youhave typed the URL correctly. If the URL should be serving existingcontent, the system administrator may need to add a new request URLmapping to the intended application." - You cannot call a method on a null-valued expression. Cannot indexinto a null array.
直到现在还没有有效的答案
有谁知道为什么会有差异以及如何解决问题?
Does anyone know why there are differences and how to solve the problem?
推荐答案
你试过Set-ExecutionPolicy Unrestricted
using ( new Impersonator( "myUsername", "myDomainname", "myPassword" ) )
{
using (RunspaceInvoke invoker = new RunspaceInvoke())
{
invoker.Invoke("Set-ExecutionPolicy Unrestricted");
}
}
