从 1.1.1 升级错误:“FileMode"存在于“System.IO.FileSystem.Primitives"和“System.Runtime, Version=4.2.0.0"中

本文介绍了从 1.1.1 升级错误:“FileMode"存在于“System.IO.FileSystem.Primitives"和“System.Runtime, Version=4.2.0.0"中的处理方法，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

将我的项目更新到 1.1.1 后，以下两行不起作用:var d = new FileStream(Path.Combine(PathToFile, $"{fileName}.txt"), FileMode.Open);var fs = new StreamReader(d,Encoding.UTF8);

After updating my project to 1.1.1 the following two lines do not work:var d = new FileStream(Path.Combine(PathToFile, $"{fileName}.txt"), FileMode.Open); var fs = new StreamReader(d,Encoding.UTF8);

当我将 chane 恢复到 csproj 文件时，错误消失了.我做错了什么?

When I reverted the chane to the csproj file, the error disappeared. What am I doing wrong?

我收到以下错误:

  1. 错误 CS0433 类型StreamReader"存在于System.IO, Version=4.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"和System.Runtime.Extensions, Version=4.2.0.0, Culture=neutral,PublicKeyToken=b03f5f7f11d50a3a'

推荐答案

参见 这里

重建 nuget 包修复了它.转到 %USERPROFILE%/.nuget 并清除所有内容.

还有这里

@ericwj 根据网络工具团队的 joe 所说，这是一个已知问题.有一个包含错误引用的 BrowserLink 包版本，这显然是 .NET Core 1.1 CLI 安装程序附带的版本.但是，在 RC.3 中，我们从 Core 1.1 模板中删除了 BrowserLink，因此新项目应该不会出现问题.

这篇关于从 1.1.1 升级错误:“FileMode"存在于“System.IO.FileSystem.Primitives"和“System.Runtime, Version=4.2.0.0"中的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
