4 C# Operators

4. C# Operators

The details of the IL language can be found in Ilinstrset.doc, which is in

C\Program Files\Microsoft.NET\FrameworkSDK\Tool Developer Guide. Reading

the screen dump of Figure 2.6, you can see that the Hello class has two  runtime for any class, and the other is the Main method. You can see that the Main method contains the entry point instruction indicating to the CLR that it is the entry point method. The next instruction of the Main method is ldstr, which loads the string literal into the local method stack. This is followed by a call to the framework class,System.Console. The last instruction is ret (which is the return of the Main method).

discussion assumes that we are dealing with numeric data types.

The +, -, /, *, and % operators have the same meaning in C# as they have in Java. In the context of two numeric operands the +,-,/,*, and %operators f dividing the LHS operand by the

RHS. shows these operators in action
