PowerShell脚本问题
代码如下：
static String checkBackUp()
{
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.Open();
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.Add("Get-WBSummary");
pipeline.Commands.Add("Out-String");
Collection<PSObject> results = new Collection<PSObject>();
try
{
results = pipeline.Invoke();
}
catch (Exception ex)
{
results.Add(new PSObject((object)ex.Message));
}
runspace.Close();
StringBuilder stringBuilder = new StringBuilder();
foreach (PSObject obj in results)
{
stringBuilder.AppendLine(obj.ToString());
}
return stringBuilder.ToString();
}
问题是这会运行每个 cmdlet（例如 Get-Process），但是当我尝试验证是否已进行备份时（Get-WBSummary >），它会输出以下错误：
术语“Get-WBSummary”未被识别为 cmdlet、函数、脚本文件或可操作程序的名称。检查名称的拼写，或者如果包含路径，请验证路径是否正确，然后重试。
但是，当我将命令直接放入 PowerShell 中时，它会执行该命令。我已经尝试添加 SnapIn 但这不起作用。
我在这里做错了什么？
Here is the code:
static String checkBackUp()
{
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.Open();
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.Add("Get-WBSummary");
pipeline.Commands.Add("Out-String");
Collection<PSObject> results = new Collection<PSObject>();
try
{
results = pipeline.Invoke();
}
catch (Exception ex)
{
results.Add(new PSObject((object)ex.Message));
}
runspace.Close();
StringBuilder stringBuilder = new StringBuilder();
foreach (PSObject obj in results)
{
stringBuilder.AppendLine(obj.ToString());
}
return stringBuilder.ToString();
}
The problem is that this runs every cmdlet (like Get-Process for example) but when I try to verify if a backup has been made (Get-WBSummary), it spits out the following error:
The term 'Get-WBSummary' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
However when I put the command straight into PowerShell, it executes the command. I have already tried to add a SnapIn but this did not work.
What am I doing wrong here?

Get-WBSummary不是常规的内置 Powershell cmdlet。 初始化运行空间后，您需要执行
Add-PSSnapin Windows.ServerBackup操作。在代码中的某个时刻
Get-WBSummaryisn't a regular built-in Powershell cmdlet. You'll need to doAdd-PSSnapin Windows.ServerBackupat some point in your code after the runspace is initialised.
您必须创建初始会话状态并添加管理单元。以下是具体操作方法
You'll have to create an initial session state and add the snapin. Here is how to do it
