由于其保护级别，无法访问该类

本文介绍了由于其保护级别，无法访问该类的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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.

由于受到保护而无法访问级别

inaccessible due to it’s protection level

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＃默认为对类型的限制最大，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 { ... }
