如何在 ASP.NET .NET 7 中读取最小 api 中的配置值

Question

我有现有代码，正在从 .NET5 升级到 .NET 6

目前我有这样的

ApplicationInsightsServiceOptions aiOptions = new ApplicationInsightsServiceOptions();
aiOptions.EnableAdaptiveSampling = false;
aiOptions.InstrumentationKey = Configuration["ApplicationInsights:InstrumentationKey"];
aiOptions.EnableQuickPulseMetricStream = true;
builder.Services.AddApplicationInsightsTelemetry();

如何注入要在最小中使用的配置依赖项？

  aiOptions.InstrumentationKey = Configuration["ApplicationInsights:InstrumentationKey"];

Answer 1

假设您有权访问：var builder = WebApplication.CreateBuilder(args);

只需使用：

builder.Configuration.GetSection("ApplicationInsights").["InstrumentationKey"];

或者

builder.Configuration["ApplicationInsights:InstrumentationKey"]
