Hi All, I converted some code from vb to c#. I am having troubles with one line:
mail = CreateObject("CDO.Message") this was the vb code. After converting to C#:
mail = Interaction.CreateObject("CDO.Message");
I am getting the error "The name interaction does not exist in the current context."
Do I need to include some sort of using directive or what? Any help would be greatly appreciated. I looked on Google, but did not have much luck.

Thank-you,
D

In order to use the Interaction class, your C# project has to have a reference to Microsoft.VisualBasic.dll (see here[^]), which is a very heavy import for just one function.

The "proper" .NET way to do this is to use something like this (in .NET 4):

C#

dynamic comObject = Activator.CreateInstance(Type.GetTypeFromProgID(typeName, true));
