Hello all, while taking a break from larger projects I decided to make a TUT series I will be going "back to basics" showing some of the most commonly used methods in C#, I know these type of tuts are all over youtube, and I am by no means an expert, but hopefully it can help out a few members here Part 1 - if else statements https://www.youtube.com/watch?v=bLNkeEqFZV8 Reference Code: Code: if (textBox1.Text == textBox2.Text) { resultLbl.Text = "text boxes match"; } else { resultLbl.Text = "text boxes do not match"; }
Part 2 switch statements https://www.youtube.com/watch?v=R1mPzK5pFyw Reference code: Code: int value = int.Parse(textBox1.Text); switch (value) { case 1: resultLbl.Text = "the number is " + 1; break; case 2: resultLbl.Text = "the number is " + 2; break; case 3: resultLbl.Text = "the number is " + 3; break; default: resultLbl.Text = "the number is not valid"; break; }
Part 3 While Loops Here's a console example static void Main(string[] args) { int x = 0;// our integer variable while (x < 16)//we are going to "loop" 16 times so our results show 0-15 { Console.WriteLine(x);//write our number each time we loop x++;//add 1 to our variable each time we loop so we stop correctly } } ****************************************************************************************************************************** Here's a form example private void button1_Click(object sender, EventArgs e) { int myNum = 0;// this time we will use an integer variable while (myNum < 16)//we are going to "loop" 16 times so our results show 0-15 { //write our number with a statement to our text box each time we loop textBox1.AppendText("Current Loop Count: " +myNum+"\n"); //add 1 to our variable each time we loop so we stop correctly myNum++; } } ******************************************************************************************************************************* now here is an extra long way of accomplishing the exact same result as our first console version above, but shows how to use a "bool" as a switch to stop whatever code you have running inside the loop, here we run a loop inside a loop :LOL: Code: static void Main(string[] args) { bool x = false;// Our bool will be used to turn the loop on and off int myNum = 0;//variable to use in the 2nd while loop while (x == false)//while our bool is false { //here your program could run anything for any amount of time you choose while(myNum < 16)//we are going to "loop" 16 times so our results show 0-15 { Console.WriteLine(myNum);//write our number each time we loop myNum++;//add 1 to our variable each time we loop so we stop correctly } x = true; //turn our bool true to stop our main loop } }
Part 4 For Loops A "for" loop is almost like the "while" loop we learned about above so here we will write the same program using a for loop instead (results will be same as pics in above post) Here's a console example Code: static void Main(string[] args) { int myNum = 0;//variable to use while counting up our loop //for loops look intimidating but here's how they break down // our variable i ; if it is less than 16 ; add 1 to our variable for (int i = 0; i < 16; i++) { Console.WriteLine(myNum);//print our number myNum++;//add one to our number } Console.Read(); } ************************************************************************** Here's a form example Code: private void button1_Click(object sender, EventArgs e) { int myNum = 0;// our integer variable // our variable i ; if it is less than 16 ; add 1 to our variable for (int i = 0; i < 16; i++) { //write our number with a statement to our text box each time we loop textBox1.AppendText("Current Loop Count: " +myNum+"\n"); //add 1 to our variable each time we loop myNum++; } }
