How do I connect to a SQL database using C#?

You can connect to a SQL database in C# using the SqlConnection class from the System.Data.SqlClient namespace.

Can you show me a code example?

Sure! Here's a simple example:

using System.Data.SqlClient;

string connectionString = "your_connection_string_here";
using (SqlConnection connection = new SqlConnection(connectionString))
{
    connection.Open();
    // Your code to interact with the database
}

What should I include in the connection string?

The connection string typically includes the server name, database name, user ID, and password. For example:

"Server=myServerAddress;Database=myDataBase;User Id=myUsername;Password=myPassword;".

Are there any common errors I should watch out for?

Yes, common errors include incorrect connection strings, network issues, and SQL Server not being accessible. Always check your connection string and server status.
