無需等待結果就執行PowerShell腳本

Question

我嘗試從c＃執行PowerShell腳本而無需等待結果。

string cmdArg = "MyScript.ps1"; 
//Create New Runspace 
Runspace runspace = RunspaceFactory.CreateRunspace(); 
runspace.ApartmentState = System.Threading.ApartmentState.STA; 
runspace.ThreadOptions = PSThreadOptions.UseCurrentThread; 
runspace.Open(); 

//Adds the command 
pipeline.Commands.AddScript(cmdArg); 
pipeline.Commands[0].MergeMyResults(PipelineResultTypes.Error, PipelineResultTypes.Output); 

//Do not wait for a result 
pipeline.InvokeAsync(); 
runspace.Close(); 

但它一直等到劇本結束！

Answer 1

使用BeginInvoke - 因爲這MSDN樣品中強調 - http://msdn.microsoft.com/en-us/library/windows/desktop/ee706580(v=vs.85).aspx。該腳本運行asynchronously和events are used to handle the output。

// Invoke the pipeline asynchronously. 
IAsyncResult asyncResult = powershell.BeginInvoke<PSObject, PSObject>(null, output); 

Answer 2

這有幫助嗎？

，你應該使用RunSpace.OpenAsync（）方法用於非同步的備註狀態....
