Om jag har en if sats som den nedan och sedan sätter variabeln till HomeTeamH1ResSer2,
varför får jag då error :
Compiler Error Message: CS0165: Use of unassigned local variable 'HomeTeamH1ResSer2'

Om koden inte går in i if-satsen så kommer variabeln vara unassigned, därför får du det felet. Om du vet att den alltid kommer sättas kan du göra en fuling och deklarera variabeln såhär:

int HomeTeamH1ResSer2 = 0;

/Johan

Det kommer den att göra.

Tack

varför inte bara byta ut

else if (m.H1ResSer2 == 0)

mot

else

blir enklare att förstå för alla (inklusive kompilatorn)

Det går inte för jag har flera if satser sedan! Men det kanske finns smartare lösningar?
