[C#]无法获取源 https://api.nuge t.org/v3-index存储签名信息解决方法

参考网上大部分方法错误，根本不起作用。正确方法是

C:\Users\你的用户名\AppData\Roaming\NuGet找到NuGet.Config打开，看到类似下面信息（可能不一样）

复制代码

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageRestore>
    <add key="enabled" value="True" />
    <add key="automatic" value="True" />
  </packageRestore>
  <bindingRedirects>
    <add key="skip" value="False" />
  </bindingRedirects>
  <packageManagement>
    <add key="format" value="0" />
    <add key="disabled" value="False" />
  </packageManagement>
  <packageSources>
    <add key="nuget-ch" value="https://nuget.cdn.azure.cn/v3/index.json" />
    <add key="Microsoft Visual Studio Offline Packages" value="C:\Program Files (x86)\Microsoft SDKs\NuGetPackages\" />
  </packageSources>
  <activePackageSource>
    <add key="nuget-ch" value="https://nuget.cdn.azure.cn/v3/index.json" />
  </activePackageSource>
</configuration>

找到关键词 https://api.nuget.org/v3/index.json

在关键词上下行加<disabledPackageSources>包裹起来，没有的话就把下面3行放对应位置

复制代码

    <disabledPackageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    </disabledPackageSources>

最后

复制代码

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <disabledPackageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    </disabledPackageSources>
    <add key="huawei" value="https://repo.huaweicloud.com/repository/nuget/v3/index.json" />
    <add key="Microsoft Visual Studio Offline Packages" value="C:\Program Files (x86)\Microsoft SDKs\NuGetPackages\" />
    <add key="azure" value="https://nuget.cdn.azure.cn/v3/index.json" />
    <add key="tencent" value="https://mirrors.cloud.tencent.com/nuget/" />
  </packageSources>
  <packageRestore>
    <add key="enabled" value="True" />
    <add key="automatic" value="True" />
  </packageRestore>
  <bindingRedirects>
    <add key="skip" value="False" />
  </bindingRedirects>
  <packageManagement>
    <add key="format" value="0" />
    <add key="disabled" value="False" />
  </packageManagement>
</configuration>

注意：如果你项目里面有Nuget.config同样设置下
