项目文件中增加如下配置
<PropertyGroup Condition="$(TargetFramework.Contains('-android')) and '$(Configuration)' == 'Release'"><AndroidKeyStore>True</AndroidKeyStore><AndroidSigningKeyStore>myapp.keystore</AndroidSigningKeyStore><AndroidSigningKeyAlias>key</AndroidSigningKeyAlias><AndroidSigningKeyPass></AndroidSigningKeyPass><AndroidSigningStorePass></AndroidSigningStorePass></PropertyGroup>发布
dotnet publish -f:net6.0-android -c:Release /p:AndroidSigningKeyPass=youpwd /p:AndroidSigningStorePass=youpwd替换命令中的 youpwd
