如何将 NPOI 库添加到 .NET Core 1.0 项目？

Question

我想将 NPOI 库添加到我的 .NET Core 项目中。我想使用 xls 和 xlsx 文件。

Answer 1

将 NPOI 库添加到 .NET Core 项目有 4 个步骤。

在 project.json 文件中添加 net451 作为框架属性下的依赖项，并包含对 NPOI 库的引用：

"frameworks": {
 "netcoreapp1.0": {
   "imports": [
     "dotnet5.6",
     "portable-net45+win8"
   ]
 },
 "net451": {
   "dependencies": {
      "NPOI": "2.2.1"
   }
  }
},

在 project.json 文件中，添加 runtimes 作为顶层属性:

 "runtimes": {
 "win7-x64": {},
 "win7-x86": {},
 "osx.10.11-x64": {},
 "ubuntu.14.04-x64": {},
 "centos.7-x64": {},
 "rhel.7.2-x64": {},
 "debian.8-x64": {}
}

在 project.json 文件中，从顶级属性 dependencies[=25= 中删除 Microsoft.NETCore.App 属性 ]
```
"Microsoft.NETCore.App": {
  "version": "1.0.0",
  "type": "platform"
},
```

在project.json文件中，去掉顶层frameworks下的netcoreapp1.0属性属性:

 "netcoreapp1.0": {
  "imports": [
    "dotnet5.6",
    "portable-net45+win8"
  ]
},

完整 project.json 文件示例：
