Cs8070 c# control cannot fall out of switch from final case label (case 1:)

C# Compiler Error

CS0163 – Control cannot fall through from one case label (‘label’) to another

Reason for the Error

You will receive this error when you DONOT explicitly terminate a switch statement in C#.

For example, try compiling the below code snippet.

using System; namespace ConsoleApp2 { class Program { public static void Main() { int val = 10; switch(val) { case 1: Console.WriteLine("Case 1"); case 2: break; } } } }

You will receive the error code CS0163 in C# for the above code snippet because the section (case 1 ) is not terminated explicitly using break.

Solution

When the switch statement contains multiple cases, it will need to be terminated by one of the following keywords : return, goto, break, throw, continue.

The error in the above code can be fixed by adding break to terminate the case 1 as show below.

using System; namespace ConsoleApp2 { class Program { public static void Main() { int val = 10; switch(val) { case 1: Console.WriteLine("Case 1"); break; case 2: break; } } } }
