## About
|
||
|
|
|
||
|
|
MySQL provides connectivity for client applications developed in .NET compatible programming languages with MySQL Connector/NET through a series of packages.
|
||
|
|
|
||
|
|
MySql.Data is the core package of Connector/NET. It is compatible with .NET Framework 4.6+ and .NET 6.0+ and provides classic MySQL protocol and MySQL X DevAPI capabilities.
|
||
|
|
|
||
|
|

|
|
|

|
|
```
|
||
|
|
MySql.Data.MySqlClient.MySqlConnection myConnection;
|
||
|
|
string myConnectionString;
|
||
|
|
//set the correct values for your server, user, password and database name
|
||
|
|
myConnectionString = "server=127.0.0.1;uid=root;pwd=12345;database=test";
|
||
|
|
|
||
|
|
try
|
||
|
|
{
|
||
|
|
myConnection = new MySql.Data.MySqlClient.MySqlConnection(myConnectionString);
|
||
|
|
//open a connection
|
||
|
|
myConnection.Open();
|
||
|
|
|
||
|
|
// create a MySQL command and set the SQL statement with parameters
|
||
|
|
MySqlCommand myCommand = new MySqlCommand();
|
||
|
|
myCommand.Connection = myConnection;
|
||
|
|
myCommand.CommandText = @"SELECT * FROM clients WHERE client_id = @clientId;";
|
||
|
|
myCommand.Parameters.AddWithValue("@clientId", clientId);
|
||
|
|
|
||
|
|
// execute the command and read the results
|
||
|
|
using var myReader = myCommand.ExecuteReader()
|
||
|
|
{
|
||
|
|
while (myReader.Read())
|
||
|
|
{
|
||
|
|
var id = myReader.GetInt32("client_id");
|
||
|
|
var name = myReader.GetString("client_name");
|

|
|
// ...
