What is the significance of parameters in SQL commands, and how do you handle them in ADO.NET?

Parameters are used to pass values to SQL commands or stored procedures. They provide

a way to safely and securely inject data into queries, reducing the risk of SQL injection

attacks.

In ADO.NET, you handle parameters using the Parameters collection of a SqlCommand

object.

Example:

SqlCommand command = new SqlCommand("SELECT * FROM Customers WHERE

CustomerID = @CustomerID", connection);

command.Parameters.AddWithValue("@CustomerID", customerId);
