Conditional Expressions C# with Example



Conditional Expressions C# with Example

When the following is compiled, it will return a different value depending on which directives are defined. 
// Compile with /d:A or /d:B to see the difference 
string SomeFunction() 
{ 
#if A 
return "A"; 
#elif B 
return "B"; 
#else 
return "C"; 
#endif 
} 
Conditional expressions are typically used to log additional information for debug builds. 
void SomeFunc() 
{ 
try 
{ 
SomeRiskyMethod(); 
} 
catch (ArgumentException ex) 
{ 
#if DEBUG 
log.Error("SomeFunc", ex); 
#endif 
HandleException(ex); 
} 
}
