Question

I am new to ADO.net. I actually created a sample database and a sample stored procedure. I am very new to this concept. I am not sure of how to make the connection to the database from a C# windows application. Please guide me with some help or sample to do the same.

Something like this… (assuming you’ll be passing in a Person object)

public int Insert(Person person) { SqlConnection conn = new SqlConnection(connStr); conn.Open(); SqlCommand dCmd = new SqlCommand('InsertData', conn); dCmd.CommandType = CommandType.StoredProcedure; try { dCmd.Parameters.AddWithValue('@firstName', person.FirstName); dCmd.Parameters.AddWithValue('@lastName', person.LastName); dCmd.Parameters.AddWithValue('@age', person.Age); return dCmd.ExecuteNonQuery(); } catch { throw; } finally { dCmd.Dispose(); conn.Close(); conn.Dispose(); } }
