<\/span><\/h2>\nTo access values from appsettings.json, we need to utilize the IConfiguration<\/code> interface provided by .NET Core. This interface acts as a bridge between our application and the configuration settings. To get started, add a reference to the Microsoft.Extensions.Configuration<\/code> namespace in your code file.<\/p>\nNext, inject the IConfiguration<\/code> interface into your class. Let’s say we have a class named “MyClass” that requires retrieving settings:<\/p>\n“`csharp
\nusing Microsoft.Extensions.Configuration;<\/p>\n
public class MyClass
\n{
\n private readonly IConfiguration _configuration;<\/p>\n
public MyClass(IConfiguration configuration)
\n {
\n _configuration = configuration;
\n }<\/p>\n
public void DoSomethingWithSettings()
\n {
\n \/\/ Retrieve values from appsettings.json using IConfiguration instance
\n }
\n}
\n“`<\/p>\n
Now, to retrieve the values from appsettings.json, you can use the GetValue<\/code> method provided by the IConfiguration<\/code> interface:<\/p>\n“`csharp
\npublic void DoSomethingWithSettings()
\n{
\n string mySetting = _configuration.GetValue(“MySetting”);
\n string connectionString = _configuration.GetConnectionString(“DefaultConnection”);
\n}
\n“`<\/p>\nBy providing the appropriate key, you can retrieve values of any type specified in appsettings.json.<\/p>\n
