webapi dotnet Program.cs 的封装

webapi dotnet Program.cs 的封装

精简代码

1. 拆分成两个部分RegisterServices(builder);和ConfigureApplication(app);
2. 或者使用代码块，大括号来进行拆分.

using HtmlTags;
using MediatR;
using Microsoft.AspNetCore.Builder;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
var builder = WebApplication.CreateBuilder(args);

RegisterServices(builder);
var app = builder.Build();

ConfigureApplication(app);
app.Run();

// 👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇
static void RegisterServices(WebApplicationBuilder builder)
{
    var services = builder.Services;
    services.AddDbContext<SchoolContext>(options =>
        options.UseSqlServer(builder.Configuration.GetConnectionString("DefaultConnection")));
    // ......
}
// 👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇👇
static void ConfigureApplication(WebApplication app)
{
    if (!app.Environment.IsDevelopment())
    {
        app.UseExceptionHandler("/Error");
        // ......
    }
    app.UseStaticFiles();
    // ......
}
