c#中的函数相当于Vb6中的CreateObject

VB6 Code:

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# Code :-

c#代码:-

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

Then I try to convert line#6 of VB code to c# as :-

然后我试着将VB代码的第6行转换为c# as:-

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

but I couldn't casting instance object to SiebelHTMLApplication like :-

但是我不能将实例对象强制转换为SiebelHTMLApplication，比如:-

sApp = (SiebelHTMLApplication)instance;

Can any one suggest me an idea how to set it ?

谁能给我建议一下如何设置它吗?

3 个解决方案

#1

Type.GetTypeFromProgID creates the com instance but not the Type object.

类型。GetTypeFromProgID创建com实例，而不是类型对象。

Try

试一试

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

You have to replace AssemblyName with the name of the Assembly which contains the Siebel.Desktop_Integration_Application description.

必须用包含Siebel的程序集的名称替换程序集名称。Desktop_Integration_Application描述。

You could always import Microsoft.VisualBasic and then just use CreateObject ?

你可以一直导入微软。VisualBasic然后使用CreateObject ?

Thank to Vasiliy, Finally I got the solution by changing from object to type. Then It's working now !!

谢谢Vasiliy，最终我通过对象到类型的转换得到了解决方案。那现在就开始工作了!!

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