# ASP.NET Core, Dapper ORM and MySql
A project example using ASP.NET Core, Dapper ORM and MySQL.
What you need to do
-------------------
First, install the following applications:
- [.NET Core SDK](https://www.microsoft.com/net/download/core)
- [Visual Studio Code](https://code.visualstudio.com/)
- [C# for Visual Studio Code](https://marketplace.visualstudio.com/items?itemName=ms-vscode.csharp)
- [MySQL Community Edition](https://dev.mysql.com/downloads/mysql/)
Considering that you know a little about .Net Core, open the 'Visual Studio Code' and create a new .NET Core web project.
Apply the nuget packages listed below:
- [Dapper](https://www.nuget.org/packages/Dapper)
- [Dapper.Contrib](https://www.nuget.org/packages/Dapper.Contrib/)
- [MySqlConnector](https://www.nuget.org/packages/MySqlConnector/)
Open the file 'appsettings.json' and put yours MySQL's configurations like the example below:
```json
"ConnectionStrings": {
"ConnectionString1": "host=localhost;port=3306;user id=USER;password=PASSWORD;database=DATABASENAME;"
}
```
Create a directory called 'Code' in the root folder of your project and in this folder create a class file called 'ConnectionStringList.cs' with the following content:
```csharp
namespace AspNetCoreDapperMySql.Code
{
public class ConnectionStringList
{
public string ConnectionString1 { get; set; }
}
}
```
Now, create other directory called 'Models' and three classes files with the following contents:
`Pais.cs`
```csharp
using Dapper.Contrib.Extensions;
using System.Collections.Generic;
namespace AspNetCoreDapperMySql.Models
{
[Table("GLB_Pais")]
public class Pais
{
[Key]
public int Id { get; set; }
public string Nome { get; set; }
public ICollection Ufs { get; set; }
}
}
```
`Uf.cs`
```csharp
using Dapper.Contrib.Extensions;
using System.Collections.Generic;
namespace AspNetCoreDapperMySql.Models
{
[Table("GLB_UF")]
public class Uf
{
[Key]
public int Id { get; set; }
public int Id_GLB_Pais { get; set; }
public string Nome { get; set; }
public string Sigla { get; set; }
public Pais Pais { get; set; }
public ICollection Cidades { get; set; }
}
}
```
`Cidade.cs`
```csharp
using Dapper.Contrib.Extensions;
namespace AspNetCoreDapperMySql.Models
{
[Table("GLB_Cidade")]
public class Cidade
{
[Key]
public int Id { get; set; }
public int Id_GLB_UF { get; set; }
public string Nome { get; set; }
public Uf Uf { get; set; }
}
}
```
And, create another directory called 'Repository' and two classes files with the following contents:
`IRepositoryBase.cs`
```csharp
using AspNetCoreDapperMySql.Models;
using System.Collections.Generic;
namespace AspNetCoreDapperMySql.Repository
{
internal interface IRepositoryBase
{
List SearchCidades(string nome);
List SearchUfs(string nome);
List SearchPaises(string nome);
}
}
```
`RepositoryBase.cs`
```csharp
using AspNetCoreDapperMySql.Code;
using AspNetCoreDapperMySql.Models;
using Dapper;
using Microsoft.Extensions.Options;
using MySql.Data.MySqlClient;
using System.Collections.Generic;
using System.Data;
using System.Data.SqlClient;
using System.Linq;
namespace AspNetCoreDapperMySql.Repository
{
public class RepositoryBase : IRepositoryBase
{
private readonly IDbConnection _db;
public RepositoryBase(IOptions connectionStrings)
{
_db = new MySqlConnection(connectionStrings.Value.ConnectionString1);
}
public void Dispose()
{
_db.Close();
}
public List SearchCidades(string nome)
{
nome = "Juiz de Fora";
if (string.IsNullOrEmpty(nome))
return _db.Query("SELECT * FROM GLB_Cidade ORDER BY Nome ASC LIMIT 10").ToList();
nome = nome.Trim();
return _db.Query("SELECT * FROM GLB_Cidade WHERE Nome LIKE @Nome ORDER BY Nome ASC LIMIT 10", new { Nome = string.Format("%{0}%", nome) }).ToList();
}
public List SearchUfs(string nome)
{
if (string.IsNullOrEmpty(nome))
return _db.Query("SELECT * FROM GLB_UF ORDER BY Nome ASC LIMIT 10").ToList();
nome = nome.Trim();
return _db.Query("SELECT * FROM GLB_UF WHERE Nome LIKE @Nome ORDER BY Nome ASC LIMIT 10", new { Nome = string.Format("%{0}%", nome) }).ToList();
}
public List SearchPaises(string nome)
{
if (string.IsNullOrEmpty(nome))
return _db.Query("SELECT * FROM GLB_Pais ORDER BY Nome ASC LIMIT 10").ToList();
nome = nome.Trim();
return _db.Query("SELECT * FROM GLB_Pais WHERE Nome LIKE @Nome ORDER BY Nome ASC LIMIT 10", new { Nome = string.Format("%{0}%", nome) }).ToList();
}
}
}
```
