编程语言: c#
数据库: MongoDB
框架: ASP.Net Core 3.1
关于.Net Core的安装,参考:
安装程序包:
MongoDB.Driver
配置文件设置:
appsettings.Development.json
"StackDatabaseSettings": {
"CollectionName": "StackRows",
"ConnectionString": "mongodb://localhost:27017",
"DatabaseName": "StackRowsDb"
}
数据库配置参数接口:
public interface IStackDatabaseSettings
{
string CollectionName { get; set; }
string ConnectionString { get; set; }
string DatabaseName { get; set; }
}
public class StackDatabaseSettings : IStackDatabaseSettings
{
public string CollectionName { get; set; }
public string ConnectionString { get; set; }
public string DatabaseName { get; set; }
}
Startup:
public void ConfigureServices(IServiceCollection services)
services.Configure<StackDatabaseSettings>(Configuration.GetSection(nameof(StackDatabaseSettings)));
services.AddSingleton<IStackDatabaseSettings>(sp =>
sp.GetRequiredService<IOptions<StackDatabaseSettings>>().Value);
}
使用:
StackService
public class StackService
{
private readonly IMongoCollection<Row> _rows;
public StackService(IStackDatabaseSettings settings)
{
var client = new MongoClient(settings.ConnectionString);
var database = client.GetDatabase(settings.DatabaseName);
_rows = database.GetCollection<Row>(settings.CollectionName);
}
public List<Row> Get() =>
_rows.Find(Row => true).ToList();
public Row Get(string id) =>
_rows.Find<Row>(Row => Row.Id == id).FirstOrDefault();
public Row Create(Row Row)
{
_rows.InsertOne(Row);
return Row;
}
public void Update(string id, Row RowIn) =>
_rows.ReplaceOne(Row => Row.Id == id, RowIn);
public void Remove(Row RowIn) =>
_rows.DeleteOne(Row => Row.Id == RowIn.Id);
public void Remove(string id) =>
_rows.DeleteOne(Row => Row.Id == id);
}
