ASP.Net5 Startup.cs ConfigurationBuilder [英] ASP.Net5 Startup.cs ConfigurationBuilder

问题描述

使用VS 2015年MVC的测试版8，我收到以下错误

 严重code描述项目文件行
错误CS1503参数1：不能从'字符串'到'Microsoft.Framework.Configuration.IConfigurationProviderNewInventory.DNX核心5.0˚F转换：\\项目\\ NewInventory的\\ src \\ NewInventory \\ Startup.cs 35
 

从我startup.cs的这一部分：

 公共启动（IHostingEnvironment ENV，IApplicationEnvironment appEnv）
        {
            //设置配置资源。            VAR建设者=新ConfigurationBuilder（appEnv.ApplicationBasePath）
                .AddJsonFile（config.json）
                .AddJsonFile（$配置{} env.EnvironmentName以.json，可选的：真正的）;            如果（env.IsDevelopment（））
            {
                //这个读取来自秘专卖店的配置项。
                //有关使用用户秘专卖店看到http://go.microsoft.com/fwlink/?LinkID=532709更多详情
                builder.AddUserSecrets（）;
            }
            builder.AddEnvironmentVariables（）;
            配置= builder.Build（）;
        }
 

当我将鼠标悬停在ConfigurationBuilder我可以看到它找'ConfigurationBuilder.ConfigurationBuilder（PARAMS IConfigurationProvider []提供商）

我要如何改变appEnv.ApplicationBasePath到IConfigurationProvider阵列？

我project.json是：

解决方案

有 ConfigurationBuilder 有 appEnv.ApplicationBasePath 作为参数，而是有 SetBasePath 方法。

因此​​，改变你的code为：

  VAR建设者=新ConfigurationBuilder（）
                .SetBasePath（appEnv.ApplicationBasePath）
                .AddJsonFile（config.json）
                .AddJsonFile（$配置{} env.EnvironmentName以.json，可选的：真正的）;
 

Using VS 2015 with beta 8 of MVC, I receive the following error

"Severity   Code    Description Project File    Line
Error   CS1503  Argument 1: cannot convert from 'string' to 'Microsoft.Framework.Configuration.IConfigurationProvider'  NewInventory.DNX Core 5.0   F:\Projects\NewInventory\src\NewInventory\Startup.cs    35

from this portion of my startup.cs:

public Startup(IHostingEnvironment env, IApplicationEnvironment appEnv)
        {
            // Setup configuration sources.

            var builder = new ConfigurationBuilder(appEnv.ApplicationBasePath)
                .AddJsonFile("config.json")
                .AddJsonFile($"config.{env.EnvironmentName}.json", optional: true);

            if (env.IsDevelopment())
            {
                // This reads the configuration keys from the secret store.
                // For more details on using the user secret store see http://go.microsoft.com/fwlink/?LinkID=532709
                builder.AddUserSecrets();
            }
            builder.AddEnvironmentVariables();
            Configuration = builder.Build();
        }

When I hover over ConfigurationBuilder I can see its looking for'ConfigurationBuilder.ConfigurationBuilder(params IConfigurationProvider[] providers)'

How do I change the appEnv.ApplicationBasePath to an IConfigurationProvider array?

my project.json is:

{
  "webroot": "wwwroot",

解决方案

There is no more constructor of ConfigurationBuilder having appEnv.ApplicationBasePath as argument, but instead there is SetBasePath method.

So change your code to:

var builder = new ConfigurationBuilder()
                .SetBasePath(appEnv.ApplicationBasePath)
                .AddJsonFile("config.json")
                .AddJsonFile($"config.{env.EnvironmentName}.json", optional: true);
