Getting Started

Nuget

You can run the following command to install the Sikiro.Tookits in your project。

PM> Install-Package Sikiro.Tookits

What does it have？

• Base ```c# var pl = new PageList(1, 10, 100, new List());

var sr = new ServiceResult(); if (sr.Error) return;

* Extension

DataTable dt = list.ToDataTable();

int numString = "1".TryInt(1);

* Helper

Sikiro.Nosql.Mongo

This is mongo repository.Base on MongoDB.Driver.It is easy to use.

Getting Started

Nuget

You can run the following command to install the Sikiro.Nosql.Mongo in your project。

PM> Install-Package Sikiro.Nosql.Mongo

Connection

var mongoRepository = new MongoRepository("mongodb://10.1.20.143:27017");

Defining User Entity

[Mongo("Chengongtest", "User")]
public class User : MongoEntity
{
    public string Name { get; set; }

[BsonDateTimeOptions(Kind = DateTimeKind.Local)]
public DateTime BirthDateTime { get; set; }

public User Son { get; set; }

public int Sex { get; set; }

public List<string> AddressList { get; set; }
}

Add

var addresult = mongoRepository.Add(new User
{
    Name = "skychen",
    BirthDateTime = new DateTime(1991, 2, 2),
    AddressList = new List { "guangdong", "guangzhou" },
    Sex = 1,
    Son = new User
    {
        Name = "xiaochenpi",
        BirthDateTime = DateTime.Now
    }
});

UPDATE

Update according to the condition part field

c#
mongoRepository.Update(a => a.Id == u.Id, a => new User { AddressList = new List { "guangdong", "jiangmen", "cuihuwan" } });

You can also update the entity field information based on the primary key

c#
getResult.Name = "superskychen";
mongoRepository.Update(getResult);

DELETE

Delete according to the condition

c#
mongoRepository.Delete(a => a.Id == u.Id);

QUERY

GET

Get the first data by filtering condition

var getResult = mongoRepository.Get(a => a.Id == u.Id);

TOLIST

You can also query qualified data list.

c#
var listResult = mongoRepository.ToList(a => a.Id == u.Id);

PAGELIST

var listResult = mongoRepository.PageList(a => a.Id == u.Id, a => a.Desc(b => b.BirthDateTime), 1, 10);

Finally a complete Demo

var url = "mongodb://10.1.20.143:27017";
var mongoRepository = new MongoRepository(url);

var u = new User
{
    Name = "skychen",
    BirthDateTime = new DateTime(1991, 2, 2),
    AddressList = new List { "guangdong", "guangzhou" },
    Sex = 1,
    Son = new User
    {
        Name = "xiaochenpi",
        BirthDateTime = DateTime.Now
    }
};
var addresult = mongoRepository.Add(u);
var getResult = mongoRepository.Get(a => a.Id == u.Id);
getResult.Name = "superskychen";
mongoRepository.Update(getResult);
mongoRepository.Update(a => a.Id == u.Id, a => new User { AddressList = new List { "guangdong", "jiangmen", "cuihuwan" } });
mongoRepository.Exists(a => a.Id == u.Id);
mongoRepository.Delete(a => a.Id == u.Id);

ExcelClient

基于NPOI封装

Getting Started

注册

 public void ConfigureServices(IServiceCollection services)
{
    services.AddExcelClient("http://rpc.gshichina.com/api/file");
}

MVC导出

使用Get请求方式新开页面导出Excel ```c# public class DefaultController : Controller { private readonly ExcelClient _ec;

    public DefaultController(ExcelClient ec)
    {
        _ec = ec;
    }

public void Index()
{
    var list = new List<student>
    {
        new Student
        {
            Id = "1",
            Name = "123123"
        },
        new Student
        {
            Id = "12",
            Name = "asdasdqwe"
        }
    };
    _ec.HttpExport(list, "excel名称");
}
}

WebApi导出
```c#
[HttpGet]
public async Task> Get()
{
    var list = new List
    {
        new Student
        {
            Id = "1",
            Name = "123123"
        },
        new Student
        {
            Id = "12",
            Name = "asdasdqwe"
        }
    };
return await _ec.HttpExportAsync(list);
}

Base64导入

[HttpGet("import")]
public IEnumerable Import()
{
    var baseString = "data:application/vnd.ms-excel;base64,UEsDBBQAAAgIAFdGME8xSZgR7wAAANMCAAALAAAAX3Jl";

return _ec.HttpImport<student>(baseString);
}

form导入

public void Import()
{
    var file = Request.Form.Files[0];
    _ec.HttpImport(file);
}

DotNetCore.CAP.MySql-分布式事务（最终一致性）

基于DotNetCore.CAP.MySql与DotNetCore.CAP.RabbitMQ封装

Getting Started

注册

public void ConfigureServices(IServiceCollection services)
{
    services.AddChloeDbContext("Server=im.gshichina.com;Port=5002;Database=business_platform;Uid=ge;Pwd=shi2019");

services.AddCap(x =>
{
    x.UseMySql("Server=im.gshichina.com;Port=5002;Database=business_platform;Uid=ge;Pwd=shi2019");
    x.UseRabbitMQ(option =>
    {
        option.HostName = "rabbitmq.gshichina.com";
        option.Port = 5112;
        option.UserName = "guest";
        option.Password = "guest";
    });
    x.UseDashboard();
    x.FailedRetryCount = 5;
    x.FailedRetryInterval = 30;
});

services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
}

事务A端

[Route("api/[controller]")]
public class ValuesController : Controller
{
    private readonly ICapPublisher _capBus;
    private readonly BusinessPlatformContext _businessPlatformContext;

public ValuesController(ICapPublisher capPublisher, BusinessPlatformContext businessPlatformContext)
{
    _capBus = capPublisher;
    _businessPlatformContext = businessPlatformContext;
}

[Route("~/adonet/transaction")]
public IActionResult AdonetWithTransaction()
{
    _businessPlatformContext.UseTransactionEx(_capBus, () =>
    {
        _businessPlatformContext.Insert(new Test
        {
            Id = DateTime.Now.ToString(CultureInfo.InvariantCulture)
        });

        _capBus.Publish("sample.rabbitmq.mysql2", DateTime.Now);
    });

    return Ok();
}
}

事务B端

[Route("api/[controller]")]
public class ValuesController : Controller
{
    private readonly ICapPublisher _capBus;
    private readonly BusinessPlatformContext _businessPlatformContext;

public ValuesController(ICapPublisher capPublisher, BusinessPlatformContext businessPlatformContext)
{
    _capBus = capPublisher;
    _businessPlatformContext = businessPlatformContext;
}

[NonAction]
[CapSubscribe("#.rabbitmq.mysql2")]
public void Subscriber(DateTime time)
{
    Console.WriteLine([email protected]"{DateTime.Now} Subscriber invoked, Sent time:{time}");
}
}

注意点

1. UseTransactionEx里必须使用_capBus.Publish
2. 默认重发间隔60秒，重试第3次与第四次间隔4分钟，默认次数上限50次
3. 配置文档 ：http://cap.dotnetcore.xyz/user-guide/zh/cap/configuration/
