在.net core中启用unsafe代码

找到我们的csproj文件，在PropertyGroup节点内添加AllowUnsafeBlocks节点，代码如下：

1 <Project Sdk="Microsoft.NET.Sdk">
2   <PropertyGroup>
3     <OutputType>Exe</OutputType>
4     <TargetFramework>netcoreapp3.0</TargetFramework>
5     <AllowUnsafeBlocks>true</AllowUnsafeBlocks>
6   </PropertyGroup>
7 </Project>
