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

有4个步骤可将NPOI库添加到.NET Core项目中。

1. 添加net451为下在project.json文件的框架性的依赖，包括对NPOI库的引用：

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

2. 在project.json文件，添加runtimes作为顶级性能：

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

3. 在project.json文件中，从顶部级属性dependencies

   "Microsoft.NETCore.App": { 
       "version": "1.0.0", 
       "type": "platform" 
   }, 
   

4. 在project.json文件中删除Microsoft.NETCore.App属性，取出下顶层的netcoreapp1.0属性frameworks属性：

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

实施例完整的project.json文件：

    "userSecretsId": "aspnet-MyProjectName-xxxxxxxx-xxxx-xxxxx-xxxx-xxxxxxxxxxxx", 

    "dependencies": {
