快速使用Monimal API 快速集成Orleans 微软官网地址如下：

https://learn.microsoft.com/zh-cn/dotnet/orleans/quickstarts/build-your-first-orleans-app?source=recommendations&tabs=visual-studio

当然它的存储grain存储采用的是内存级别存储，我缓存了mssql 存储。如果是内存存储使用如下代码就Ok

 siloBuilder.AddMemoryGrainStorage("urls");

我采用的是数据库存储：

siloBuilder.AddAdoNetGrainStorage("OrleansStorage", options =>{options.Invariant = "System.Data.SqlClient";options.ConnectionString = "Server=.;Database=OrleansStorage;Persist Security Info=True;User ID=sa;password=Sasa123;";});

当然这过程中需要引入的库如下：

Microsoft.Orleans.Persistence.AdoNet： ado.net存储

Microsoft.Orleans.Server ：orleans 开启服务

System.Data.SqlClient ：ado 操作数据库驱动程序，ado.net 开发使用库

Program.cs 完整代码如下：

using Microsoft.AspNetCore.Http.Extensions;
using Orleans.Runtime;
var builder = WebApplication.CreateBuilder(args);
builder.Host.UseOrleans(siloBuilder =>
{siloBuilder.UseLocalhostClustering();//siloBuilder.AddMemoryGrainStorage("urls");siloBuilder.AddAdoNetGrainStorage("OrleansStorage", options =>{options.Invariant = "System.Data.SqlClient";options.ConnectionString = "Server=.;Database=OrleansStorage;Persist Security Info=True;User ID=sa;password=Sasa123;";});});// Add services to the container.
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();var app = builder.Build();// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{app.UseSwagger();app.UseSwaggerUI();
}app.MapGet("/", () => "Hello World!");app.MapGet("/shorten/{*path}",async (IGrainFactory grains, HttpRequest request, string path) =>{// Create a unique, short IDvar shortenedRouteSegment = Guid.NewGuid().GetHashCode().ToString("X");// Create and persist a grain with the shortened ID and full URLvar shortenerGrain = grains.GetGrain(shortenedRouteSegment);await shortenerGrain.SetUrl(path);// Return the shortened URL for later usevar resultBuilder = new UriBuilder(request.GetEncodedUrl()){Path = $"/go/{shortenedRouteSegment}"};return Results.Ok(resultBuilder.Uri);});app.MapGet("/go/{shortenedRouteSegment}",async (IGrainFactory grains, string shortenedRouteSegment) =>{// Retrieve the grain using the shortened ID and redirect to the original URL        var shortenerGrain = grains.GetGrain(shortenedRouteSegment);var url = await shortenerGrain.GetUrl();return Results.Redirect(url);});app.Run();#region grain 粒度
///

}[GenerateSerializer]
public record UrlDetails
{public string FullUrl { get; set; }public string ShortenedRouteSegment { get; set; }
}#endregion 

特别注意如果是需要数据库存储：除了加入上面包外，还需要执行相应脚本，脚本到微软官网地址找：

https://learn.microsoft.com/zh-cn/dotnet/orleans/host/configuration-guide/adonet-configuration 当然需要自己按数据库配置链接建立一个空库，然后执行对应SQL脚本。否则会运行报错

然后对应执行相应需要存储脚本：也就是官网对应的持久化，提醒、集群脚本。
