How do I get the value from textbox before it can be inserted into batabase.

myStringValue = myTextBox.Text;

SqlCommand myCommand= new SqlCommand("INSERT INTO table (Column1, Column2) " +
"Values (@firstParam, @secondParam)", myConnection);
myCommand.Parameters.AddWithValue("@firstParam", myStringValue);
myCommadn.Parameters.AddWithValue("@secondParam", myIntValue);
myCommand.ExecuteNonQuery();

this line of code "Values (@firstParam, @secondParam)",
@firstParam will this be the name of the first textbox and @secondParam the name of the second textbox etc.

Also myCommand.Parameters.AddWithValue("@firstParam", myStringValue); myStringValue will be if am getting string from the textbox.

string name = NameTB.Text;
int age = Convert.ToInt32(AgeTB.Text);

SqlConnection myConnection = new SqlConnection(myConnectionString);
SqlCommand myCommand = new SqlCommand("INSERT Person(NameField, AgeField) "+
    VALUES (@nameParam, @ageParam)", myConnection);

myCommand.Parameters.AddWithValue("@nameParam", name);
myCommand.Parameters.AddWithValue("@ageParam", age);

myConnection.Open();
myComment.ExecuteNonQuery();
myConnection.Close();
