Flow-of-Control Statements
C# provides the flow-of-control constructs common to modern programming languages.
Conditional execution
executes or skips a section of code depending on a condition. The
conditional execution statements are the following:
-
if
-
if...else
-
switch
Looping constructs
execute a section of code multiple times, where the number of times
depends on the changing state of the program. The looping statements are the
following:
-
while
-
do
-
for
-
foreach
Jump statements
change the flow of control from one section of code to a specific state-
ment in another section of code. The jump statements are the following:
-
break
-
continue
-
return
-
goto
-
throw
Conditional execution and looping constructs (other than
foreach
) require a test expres-
sion, or
condition
, to determine where the program should continue execution.
■
Note
Unlike C and C++, test expressions must return a value of type
bool
. Numbers do not have a
Boolean interpretation in C#.
