Visual Studio说名称在当前上下文中不存在 [英] Visual Studio saying name doesn't exist in current context
问题描述
我正在像这样的类上调用静态方法
I am calling a static method on a class like
Foo.bar()
Visual Studio的智能感知功能可以识别Foo并为我自动完成设置(它突出显示了Foo，并且一切正常.)一切正常，直到我去构建项目为止，并且抛出一个错误，说当前环境中不存在名称Foo.
Visual studio's intellisense recognizes Foo and autocompletes bar for me (it highlights Foo and everything like it is working fine). Everything looks fine until I go to build the project, and it throws an error saying the name Foo doesn't exist in current context.
我正在其他文件中使用此静态方法调用，所以我知道该类是可以的.这种情况太大了，无法发布代码，所以我主要是在寻找开始研究的原因，这将导致智能感知正常运行，但在这样的编译过程中会出错.
I am using this static method call in other files, so I know the class is ok. The situation is too big to post code, so I am mostly looking for reasons to start looking into that would cause intellisense to function normally but get errors on compile like this.
推荐答案
当名称空间，类和变量具有相同的名称时，如果它们纠缠在一起，就会发生这种情况.我以前曾遭受过这种痛苦.Intellisense告诉我我是对的，编译器告诉我我是错的！我相信编译器！
This can occur when namespaces, classes and variables become tangled when they have the same name. I have suffered with this before. Intellisense told me I was right, the compiler told me I was wrong! I trusted the compiler!
您有2个我能想到的选择
You have 2 options that I can think of
-
在代码中搜索Foo，并查看其是否用于静态类之外.
Search your code for Foo, and see it it is being used for something other than the static class.
完全限定Foo.bar()调用. MyApplication.This.That.Foo.bar();
Fully qualify the Foo.bar() call. MyApplication.This.That.Foo.bar();
按此顺序执行...最好以优雅的方式解决问题，因此您只需调用Foo.bar()即可，因为与拥有 MyApplication.This.That.Foo.bar(); 到处都是！
Do it in that order...it's better to elegantly resolve the issue so you can just call Foo.bar() as this is more readable and maintainable than having MyApplication.This.That.Foo.bar(); all over the place!
