你在哪里把SQL语句放在你的c#项目中？

SELECT * FROM users;
INSERT INTO users (name, email) VALUES (@name, @email);
UPDATE users SET email = @email WHERE id = @id;
DELETE FROM users WHERE id = @id;

using System.Data.SqlClient;

string connectionString = "Data Source=localhost;Initial Catalog=myDatabase;Integrated Security=True";
string sqlQuery = File.ReadAllText("SQL/Queries.sql");

using (SqlConnection connection = new SqlConnection(connectionString))
{
    connection.Open();

    using (SqlCommand command = new SqlCommand(sqlQuery, connection))
    {
        command.Parameters.AddWithValue("@name", "John Doe");
        command.Parameters.AddWithValue("@email", "john.doe@example.com");
        command.Parameters.AddWithValue("@id", 1);

        command.ExecuteNonQuery();
    }
}
