Hai Joswa,

 Thanks for answering. I am new to c#.net, kindly guide me to add any namespace or reference for below error.

Variant Set enCrypt = CreateObject("cast.cipher"); ==> It show error like"The type of namespace name 'Variant' could not be found (are you missing  a using directive or an assembly reference?)"

With Regards,

Hello Siddheswaran,

In VB, CreateObject() creates as object using progId. Here is how you do it in C#,

Type t = Type.GetTypeFromProgID("cast.cipher");
var enCrypt = Activator.CreateInstance(t);

If  you are using .NET 4.0, you can make use of dynamic. So above code can be written as,

Type t = Type.GetTypeFromProgID("cast.cipher");
dynamic enCrypt = Activator.CreateInstance(t);
enCrypt.encode(strUName, strUPwd);

But if you are not using .NET 4.0, then you can use previous method but you have to call encode method using reflection.

Answer 7

Ofcourse that will give you error (if you are not using enCrypt variable is of dynamic type). Because, when you use CreateInstance to create an object, the type of the oject will be System.Object. So, enCrypt is of System.Object type which doesn't define encode method.

To get this work doe, you need to use reflection. Let me re-write the whole code,

Type t = Type.GetTypeFromProgID("cast.cipher");
var enCrypt = Activator.CreateInstance(t);

t.GetMethod("encode").Invoke(enCrypt, new String[] { strUName, strUPwd });  //Call encode method this way.

Note: This is not tested because I don't have "cast.cipher" progId registered in my system. Also I assume that "cast.cipher" progId is availablein your system.

Thanks Adavesh and JoSwa for your fast help and support.

Hi siddheswaran,

Welcome to MSDN Forum.

We are very glad to hear that you got some good suggestions.

Adavesh  is right. The C# equivalent of VB CreateObject is something like this:

dynamic objExcel =
Activator.CreateInstance(Type.GetTypeFromProgID("Excel.Application"));

This case discussed the similar issue to yours.
