Operators in C#

Comparison Operators

Above, we used the > operator to mean “greater than.” Most of these operators are the same in C# as they are in C and other languages. In Table 2-5, note particularly that “is equal to” requires two equal signs and that “not equal” is different than in FORTRAN or VB.

>	greater than
<	less than
==	is equal to
!=	is not equal to
>=	greater than or equal to
<=	less than or equal to

Combining Conditions

When you need to combine two or more conditions in a single if or other logical statement, you use the symbols for the logical and, or, and not operators. These are totally different than any other languages except C/C++ and are confusingly like the bitwise operators shown in Table 2.

&&	logical And
||	logical Or
~	logical Not
