C# 0 The Complete Reference

goto

 statement—it is not necessary 

for making the language complete. Rather, 

goto

 is a convenience that, if used wisely, can be 

a benefit in certain programming situations. As such, the 

goto

 is not used in this book 

outside of this section. The chief concern most programmers have about the 

goto

 is its 

tendency to clutter a program and render it nearly unreadable. However, there are times 

when the use of the 

goto

 can clarify program flow rather than confuse it.

The

goto

 requires a label for operation. A 

label

 is a valid C# identifier followed by a 

colon. The label must be in the same method as the 

goto

 that uses it and within scope. For 

example, a loop from 1 to 100 could be written using a 

goto

 and a label, as shown here:

x = 1;

loop1:

  x++;

  if(x < 100) goto loop1;
