由于其保护级别，无法访问该类

问题描述

我在两个解决方案中都使用了一个项目IBSampleApp，并且它们的类在这两个类中均遇到以下编译器错误。

I have one project IBSampleApp used in two solutions and it’s classes suffer the following compiler error in both.

执行解决方案中IB执行项目的IBClient.cs错误：

Error in IBClient.cs of IB Execution project in Execution solution:

IBSampleApp项目中的TickPriceMessage类：

TickPriceMessage class in IBSampleApp project:

已将InternalsVisibleTo属性添加到IBSampleApp项目的AssemblyInfo.cs中（由@JamesFaix推荐）：

Added InternalsVisibleTo property to AssemblyInfo.cs of IBSampleApp project (recommended by @JamesFaix):

问题仍然存在。如何使TickPriceMessage类可用于两个解决方案？

The problem persistes still. How to make TickPriceMessage class available to both solutions?

推荐答案

您在内部类上有一个公共构造函数。在缺少任何访问修饰符的情况下，c＃默认为，对于像您这样的课程，它是内部的。

You have a public constructor on an internal class. With lack of any access modifier, c# defaults to the most restricted for the type which is internal for a class like yours.

// this is an "internal" class
class TickPriceMessage
{
   ...
}
