15. Statements

C# provides a variety of statements. [Note: Most of these statements will be familiar to developers who have programmed in C and C++. end note]

statement:

labeled-statement

declaration-statement

embedded-statement

embedded-statement:

block

empty-statement

expression-statement

selection-statement

iteration-statement

jump-statement

try-statement

checked-statement

unchecked-statement

lock-statement

using-statement

yield-statement

The embedded-statement non-terminal is used for statements that appear within other statements. The use of embedded-statement rather than statement excludes the use of declaration statements and labeled statements in these contexts. [Example: The code

void F(bool b) {
  if (b)
  int i = 44;
}

results in a compile-time error because an if statement requires an embedded-statement rather than a statement for its if branch. If this code were permitted, then the variable i would be declared, but it could never be used. (Note, however, that by placing i’s declaration in a block, the example is valid.) end example]
