可访问性不一致：c＃中的返回类型 [英] Inconsistent accessibility: return type in c#

问题描述

我开发了win form application。这个应用程序有2个错误

喜欢



不一致的可访问性：返回类型'System.Collections .Generic.List< pdf_clustering.lib.center>'不如方法'Pdf_Clustering.Lib.FileClustering.prepareCluster（int，System.Collections.Generic.List< pdf_clustering.lib.fileinfo>，ref int）'



另一个错误如



不一致的可访问性：参数类型'System.Collections.Generic.List< pdf_clustering .lib.fileinfo>'不如方法'Pdf_Clustering.Lib.FileClustering.prepareCluster（int，System.Collections.Generic.List< pdf_clustering.lib.fileinfo>，ref int）'

请帮我解决

解决方案

您的 Fileinfo 类没有定义任何辅助功能;所以它的默认可访问性设置为 internal 。这意味着此类仅可用于定义它的库（或可执行文件）。您不能在外部程序集中使用此类。



因此当您将其设置为 prepareCluster 中的参数时方法，定义为public，编译器警告你，尽管方法是公共的，你将无法从外部程序集中使用它，因为其中一个参数是内部类型，不会可以访问。



解决方案：将您的 Fileinfo 类标记为公开：

< pre lang =c＃> public class Fileinfo
{
// ...
}

编译器不应该在此之后抱怨。希望这会有所帮助。

I have develop win form application .this application have 2 errors
like

" Inconsistent accessibility: return type 'System.Collections.Generic.List<pdf_clustering.lib.center>' is less accessible than method 'Pdf_Clustering.Lib.FileClustering.prepareCluster(int, System.Collections.Generic.List<pdf_clustering.lib.fileinfo>, ref int)' "

another error like as

Filinfo propert class

}

please help me for solving

解决方案

Your Fileinfo class does not have any accessibility defined ; so its default accessibility is set to internal. That means that this class is usable only from the library (or the executable) that defines it. You cannot use this class from a foreign assembly.

So when you set it as a parameter in the prepareCluster method, which is defined as public, the compiler warns you about the fact that, despite the method being public, you won't be able to use it from a foreign assembly as one of the parameters is of an internal type, which will not be accessible.

Solution : mark your Fileinfo class as public:

public class Fileinfo
{
   //...
}

Compiler should not complain after that. Hope this helps.
