Microsoft® Visual C#® 2005 Step by Step (Step By Step (Microsoft))

Add an amount to a variable

Use the compound addition operator. For example:

variable += amount;

Subtract an amount from a variable

Use the compound subtraction operator. For example:

variable -= amount;

Run one or more statements while a condition is true

Use a while statement. For example:

int i = 0; while (i != 10) {     Console.WriteLine(i);     i++; }

Alternatively, use a for statement. For example:

for (int i = 0; i != 10; i++) {     Console.WriteLine(i); } 

Repeatedly execute statements one or more times

Use a do statement. For example:

int i = 0; do {     Console.WriteLine(i);     i++; } while (i != 10);
