c# - VB.NET Execution Order -

i working on converting vb source code on c#. while understand there converters automate this, , use particular dll without rewriting it, i'm doing partially can understand vb better. not expect write it, it's @ least helping me able read it.

in doing though, i've come across quite confusing. following code snippets examples, i've seen throughout program.

vb source code:

friend function allocateobjectnumber() long     allocateobjectnumber = _nextfreeobjectnumber     _nextfreeobjectnumber += 1     _objectallocatedcount += 1 end function 

my translated c# code:

    internal long allocateobjectnumber()     {         cvnextfreeobjectnumber += 1;         cvobjectallocatedcount += 1;         return cvnextfreeobjectnumber;     } 

what i'm not understanding flow control vb uses. understand allocateobjectnumber += 1 used in place of return cvnextfreeobjectnumber, if line comes before incrementing of 2 variables, how code not considered unreachable? based on c# understanding, first line in method return calling method, , whole method act pseudo-property.

any helpful explanations?

the vb approach more similar storing value in temporary variable:

internal long allocateobjectnumber() {     var nextnumber = _nextfreeobjectnumber     cvnextfreeobjectnumber += 1;     cvobjectallocatedcount += 1;     return nextnumber; } 

in vb function = value syntax doesn't return - code after can keep running. when method reaches end, value used becomes 'return' value whatever called in first place.

you can use function = value syntax multiple times in same method way of returning different result in different conditions without needing temporary variable used in example.
