All programming languages rely on keywords, which are words that are reserved and that you can’t use for your personal needs. Knowing the keywords enables you to choose other words for your code. For example, you can’t create a variable named while because it’s a C# keyword. The following table contains the C# keywords.

abstract as base bool break
byte case catch char checked
class const continue decimal default
delegate do double else enum
event explicit extern false finally
fixed float for foreach goto
if implicit in int interface
internal is lock long namespace
new null object operator out
override params private protected public
readonly ref return sbyte sealed
short sizeof stackalloc static string
struct switch this throw true
try typeof uint ulong unchecked
unsafe ushort using using static virtual
void volatile while
