c# – ‘无法在PowerShell中转换“System .__ ComObject”value

C#

System.Type t = System.Type.GetTypeFromProgID("VisualStudio.DTE.10.0",true);
object obj = System.Activator.CreateInstance(t,true);
EnvDTE80.DTE2 dte = (EnvDTE80.DTE2)obj;

dte.MainWindow.Activate();

dynamic solution = dte.Solution;
solution.Create(solution_folder_path,solution_name);
solution.SaveAs(solution_file_path);

dynamic project = solution.AddFromTemplate(template_path,project_folder_path,project_name);

TCatSysManagerLib.ITcSysManager system_manager = project.Object;

电源外壳

[System.Reflection.Assembly]::LoadFrom("C:WindowsassemblyGAC_MSILTCatSysManagerLib2.1.0.0__180016cd49e5e8c3TCatSysManagerLib.dll");

$dte = New-Object -ComObject VisualStudio.DTE.10.0

$dte.SuppressUI = $false
$dte.MainWindow | %{$_.GetType().InvokeMember("Visible","SetProperty",$null,$_,$true)}

$solution = $dte.Solution

$project = $solution.AddFromTemplate($template_path,$project_folder_path,$project_name)

[TCatSysManagerLib.ITcSysManager] $system_manager = [TCatSysManagerLib.ITcSysManager] $project.Object

我遇到的问题是PowerShell中的最后一行返回了表单的错误：

Cannot convert the “System.__ComObject” value of type
“System.__ComObject#{3b56a5ce-0c02-440b-8ced-f1f3e83f66ed}” to type
“TCatSysManagerLib.ITcSysManager”.

添加细节：

我可以在PowerShell代码中省略[TCatSysManagerLib.ITcSysManager]类型.我遇到了同样的问题但是稍后转换这个C#代码：

TCatSysManagerLib.ITcSmTreeItem gvl = system_manager.LookupTreeItem("TIPC^PLC1^PLC1 Project^GVLs^GVL");
TCatSysManagerLib.ITcPlcDeclaration gvl_declaration = (TCatSysManagerLib.ITcPlcDeclaration)gvl;
string gvl_declaration_text = System.IO.File.ReadAllText(gvl_declaration_text_file_path);
gvl_declaration.DeclarationText = gvl_declaration_text;

在这种情况下,我必须将强制转换为TCatSysManagerLib.ITcPlcDeclaration类型,以便访问gvl_declaration的DeclarationText属性.

我是C#和PowerShell的新手,并从示例中修改了这些内容.任何意见,将不胜感激.
