Question

VB6代码：

Dim oApplication As SiebelHTMLApplication
Dim oBS As SiebelService
Dim oPSIn As SiebelPropertySet
Dim oPSOut As SiebelPropertySet
Dim sActivityId As String
Set oApplication = CreateObject("Siebel.Desktop_Integration_Application.1")
If oApplication.IsReady Then
    Set oBS = oApplication.GetService("Workflow Process Manager")

C＃代码： -

SiebelHTMLApplication sApp = new SiebelHTMLApplication();
SiebelService sService = new SiebelService();
SiebelPropertySet sPsIn = new SiebelPropertySet();
SiebelPropertySet sPsOut = new SiebelPropertySet();

然后我尝试将VB代码的第6行转换为c＃： -

object instance = Activator.CreateInstance(Type.GetTypeFromProgID("Siebel.Desktop_Integration_Application.1"));

但我无法将实例对象转换为SiebelHTMLApplication，如： -

sApp = (SiebelHTMLApplication)instance;

任何人都可以建议我如何设置它吗？

Answer 1

Type.GetTypeFromProgID创建com实例，但不创建Type对象。

尝试

object instance = Activator.CreateInstance(Type.GetType("Siebel.Desktop_Integration_Application, AssemblyName"));

您必须将AssemblyName替换为包含Siebel.Desktop_Integration_Application描述的Assembly的名称。

Answer 2

您始终可以导入Microsoft.VisualBasic，然后只使用CreateObject？

Answer 3

感谢Vasiliy，最后我通过从对象更改为类型来获得解决方案。那它现在正在工作!!

var siebelDeskType = Activator.CreateInstance(Type.GetTypeFromProgID("Siebel.Desktop_Integration_Application.1"));
            sApp = (SiebelHTMLApplication)siebelDeskType;

C＃中的函数与Vb6中的CreateObject等效
