How to add numbers in a loop [closed]

I am new in c#,

I want to add the numbers in my coding .

I dont know how to loop.

I want to add numbers in a loop for each time 开发者_开发技巧i want to add 500 in my Addition

I want to do something like this in loop for every time

   int StartTime = int.Parse("90000");
   int Add = StartTime + "500";

---

int StartTime = 90000;
int Add = StartTime;
int increment = 500;

for (int i = 0; i < 10; i++) {
    Add = Add + increment;
}

// Add is 90,000 + 500 * 10 = 95,000.

The for loop syntax is a bit weird if you haven't seen it before. You have a thing to do on initialization, int i = 0, a thing to test against each time around the loop, to see if you should continue going i < 10, and a thing to do at the end of each pass around the loop, i++ (which is a shorter way of writing i = i + 1;).

So here, First there is a loop variable created, i. Then if i is less than 10, the computer goes inside the loop (and sets Add = Add + increment). Then, the computer adds 1 to i, so i is now 1. Then checks if i is still less than 10. If it is, it goes into the loop again... and so on.

When i eventually reaches 10, the condition i < 10 no longer holds, so the computer exists the loop.

So if we write this:

int StartTime = 90000;
int Add = StartTime;
int increment = 500;

for (int i = 0; i < 10; i++) {
    Console.WriteLine(Add + " " + i);
    Add = Add + increment;
}
Console.WriteLine(Add);

The output is this:

90000 0
90500 1
91000 2
91500 3
92000 4
92500 5
93000 6
93500 7
94000 8
94500 9
95000

Note that the loop variable i only exists inside the loop, so if you were to do:

int StartTime = 90000;
int Add = StartTime;
int increment = 500;

for (int i = 0; i < 10; i++) {
    Console.WriteLine(Add + " " + i);
    Add = Add + increment;
}
Console.WriteLine(Add + " " + i);

The program would not work.

---

int count = 10; //amount of times you want to loop

int StartTime = 90000;

int Add = 0;

for (int i=0; i < count; i++)
{
    Add = Add + 500;
}

Why in the world are you parsing strings to integer?

And why do you make so many lines?

int StartTime = 90000; //use an integer, not a string!
int Add = StartTime;

for (int i=0; i < 10; i++) //looping 10 times, from 0 to 10, incrementing i for 1 every time
{
    Add += 500; //so you add 500 to Add every loop
}
Console.WriteLine(Add);

Result:

95000
