从vb转换为C# [英] Converted from vb to C#

问题描述

大家好，我将一些代码从vb转换为c#.我在一条线上遇到麻烦:
mail = CreateObject("CDO.Message")这是vb代码.转换为C#后:
mail = Interaction.CreateObject("CDO.Message");
我收到错误消息在当前上下文中不存在名称交互."
我是否需要包括某种using指令?任何帮助将不胜感激.我看过Google，但运气不佳.

谢谢

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

您可能没有添加对此类交互"的引用

you may didn''t add referance to this class ''Interaction''

为了使用Interaction类，您的C#项目必须具有对Microsoft.VisualBasic.dll的引用(请参见

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):

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