asp.net - 在 ASP.NET 中导入模块 MSOnline 失败

Question

我们创建了一个用于在 asp.net 中运行 PowerShell 的迷你 Web 程序。 PowerShell 命令运行良好。但是当我们尝试导入 MSOnline 模块时，会显示以下错误:

Could not load file or assembly 'file:///C:\Windows\system32\WindowsPowerShell\v1.0\Modules\MSOnline\Microsoft.Online.Administration.Automation.PSModule.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Dim Ps As PowerShell = PowerShell.Create()

Dim tempScript As String = "Import-Module MSOnline " + Environment.NewLine
tempScript = tempScript + "$username = 'xxx@xxx.com' " + Environment.NewLine
tempScript = tempScript + "$password = 'abcd1234' " + Environment.NewLine
tempScript = tempScript + "$secureStringPwd = $password | ConvertTo-SecureString -AsPlainText -Force " + Environment.NewLine
tempScript = tempScript + "$creds = New-Object System.Management.Automation.PSCredential -ArgumentList $username, $secureStringPwd " + Environment.NewLine
tempScript = tempScript + "Connect-MsolService -Credential $creds " + Environment.NewLine
tempScript = tempScript + "Get-MsolDomain" + Environment.NewLine

Ps.Commands.AddScript(tempScript)

' Execute the script
Dim results = Ps.Invoke()

PS C:> $PSVersionTable |外串

尝试使用 process.start 调用 CMD，然后 cmd 调用 powershell，但它也失败了。同样的错误信息。

Private Function RunBatch() As String
Dim proc As New Process
Dim strBuilder As StringBuilder = New System.Text.StringBuilder

proc.StartInfo.FileName = "C:\temp\enableMFA.bat"
proc.StartInfo.UseShellExecute = False
proc.StartInfo.RedirectStandardOutput = True
proc.Start()
proc.WaitForExit()

Dim output() As String = proc.StandardOutput.ReadToEnd.Split(CChar(vbLf))
For Each ln As String In output
    strBuilder.Append(ln & vbNewLine + vbLf)
Next

Return strBuilder.ToString

End Function

错误信息:

one of its dependencies. An attempt was made to load a program with an incorrect format.

Answer 1

最后通过将CPU更改为x64解决了这个问题，这是步骤

• Right click the project >> properties >> complie >> Target CPU to x64

• Go to TOOLS >> Options >> Projects and Solutions >> Web Projects >> use 64bit IIS Express

**记得关闭VS2013再打开项目**

** Thx for the hints from David Brabant**
