===========================
C# DataRepository to MySQL!
===========================
An pretty simple, and easy form to use ADO .NET C#
No Dll's, Lib's, or anything else!
Just download the class files, put in your App_Code directory and enjoy!
**How to use!**
- First Of All!
- **1.1** Installing
- Type of Methods!
- **2.1** Modifiers
- **2.2** Retrieves
- **2.2.1** Extension Method (Verify)
- Accompaniments!
- **3.1** BusinessRepository<T>
-------------
First Of All!
-------------
**1.1 - Installing**
*You just have to download the archive class: data_repository.cs, and if you want the business_repository.cs to more explanation scroll down at the 3.1 section!*
----------------
Type of Methods!
----------------
**2.1 - Modifiers**
*Methods that will be modify rows, (INSERT, UPDATE, DELETE)*
Eg.:
```cs
public bool Add()
{
try
{
string sql = @"INSERT INTO tags (total_posts, name, uri)
VALUES (@total_posts, @name, @uri);";
return DataRepository.ChangeRecords(GetParameters(), sql);
}
catch (Exception ex)
{
throw new Exception(ex.Message);
}
}
```
Instead of use this very old and ugly form:
```cs
public bool Add()
{
bool isOk = false;
try
{
using (MySqlConnection conn = dbConnect.SiteConnection())
{
string sql = @"INSERT INTO tags (total_posts, name, uri)
VALUES (@total_posts, @name, @uri);";
using(MySqlCommand cmd = new MySqlCommand(sql, conn))
{
cmd.Parameters.Add("@name", MySqlDbType.VarChar).Value = Name;
cmd.Parameters.Add("@uri", MySqlDbType.VarChar).Value = Uri;
cmd.Parameters.Add("@total_posts", MySqlDbType.Int32).Value = TotalPosts;
conn.Open();
isOk = cmd.ExecuteNonQuery() > 0 ? true : false;
}
}
}
catch (Exception ex)
{
throw ex;
}
return isOk;
}
```
And its the same of UPDATE and DELETE methods, just changing the parameters and query of course!
**2.2 Retrieves**
To SELECT query statements you need one more method in your type class.
There is no pattern about the name. Here I just call him, FillAttributes;
He'll be used like as a Func<DataRow>.
See:
```cs
protected override Tag FillAttributes(DataRow dr)
{
return new Tag
{
ID = dr.Verify("id", Convert.ToInt32),
Name = dr.Verify("name", Convert.ToString),
Uri = dr.Verify("uri", Convert.ToString),
TotalPosts = dr.Verify("total_posts", Convert.ToString)
};
}
```
And you'll need him on these code (kept at tag.cs!)
```cs
public List List(int now, int end)
{
try
{
string strSQL = @"SELECT * FROM tbl_catalogs ORDER BY id DESC LIMIT @now, @end;";
return DataRepository.List(new Dictionary() { {"now", now}, {"end", end} },
strSQL, FillAttributes);
}
catch (Exception e)
{
throw new Exception(e.Message);
}
```
**2.2.1 Extension Method**
The method exemplicated before this explanation, verify all of collumns that comes into the DataRow object. In this form, you need define only once the method `FillAtributes`.
