ASP.Net5 Startup.cs ConfigurationBuilder [duplicate]

问题

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:

回答1:

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);
