DataBase MySql

edData is a TextBox
content of edData.text = 08/03/2020

the field Data on MySql Table is DATETIME

What I have tried:

string Datas = edData.Text.Substring(6, 4) + "-" + edData.Text.Substring(3, 2) + "-"+ edData.Text.Substring(0, 2) + " 00:00:00,000";          

DateTime data = DateTime.ParseExact(Datas, "yyyy-MM-dd HH:mm:ss,fff", System.Globalization.CultureInfo.InvariantCulture);

const string quote = "\"";

string Query = "UPDATE tb_spese ";
                   Query += " SET id_codice = " + @idCodice + ",";
                   Query += " data = " + quote +  @Datas + quote + ",";
                   Query += " entrata = " + quote + entrata + quote;

ex.Message = "Incorrect date value: '2020-03-08 00:00:00,000' for column 'data' at row 1"

And the problem is? Other than the fact that it looks like you are butchering dates instead of just using dates and date controls.

Don't do it like that!

Your code is vulnerable to SQL Injection[^]. NEVER use string concatenation to build a SQL query. ALWAYS use a parameterized query.

And there's no need to manipulate the string like that before parsing the date. Just use the correct format in ParseExact:
DateTime date = DateTime.ParseExact(edData.Text, "dd/MM/yyyy", System.Globalization.CultureInfo.InvariantCulture);

// TODO: Add a WHERE clause to limit which rows are updated:
const string Query = "UPDATE tb_spese SET id_codice = @idCodice, data = @date, entrata = @entrata"; 

using (var connection = new SqlConnection("..."))
using (var command = new SqlCommand(Query, connection))
    command.Parameters.AddWithValue("@idCodice", idCodice);
    command.Parameters.AddWithValue("@date", date);
    command.Parameters.AddWithValue("@entrata", entrata);
    // TODO: Add other parameters here for the WHERE clause.
