C# goto statement
In this chapter you will learn:
Description
The goto statement transfers execution to
another label within the statement block.
Syntax
goto statement jumps to another labeled location. It has the form of
goto label;
When using with switch statement its form is
goto case caseConstant;
A label statement is just a placeholder in a code block, denoted with a colon suffix.
Example
Example for goto statement
using System;//from w w w . j a va 2 s. c om
class Program
{
static void Main(string[] args)
{
for (int i = 0; i < 10; i++)
{
if (i == 1)
{
goto end;
}
}
end: Console.WriteLine("The end");
}
}
The output:
Example 2
The goto is C#'s unconditional jump statement.
When encountered, program flow jumps to the location specified by the goto.
The goto requires a label for operation.
A label is a valid C# identifier followed by a colon.
using System; //w w w.j a va 2s . com
class SwitchGoto {
public static void Main() {
for(int i=1; i < 5; i++) {
switch(i) {
case 1:
Console.WriteLine("In case 1");
goto case 3;
case 2:
Console.WriteLine("In case 2");
goto case 1;
case 3:
Console.WriteLine("In case 3");
goto default;
default:
Console.WriteLine("In default");
break;
}
Console.WriteLine();
}
}
}
The code above generates the following result.
