Compiler Error CS0163
Visual Studio 2012
Control cannot fall through from one case label ('label') to another
When a switch statement contains more than one switch section, you must explicitly terminate each section, including the last one, by using one of the following keywords:
If you want to implement "fall through" behavior from one section to the next, use goto case #. For more information and examples, see switch (C# Reference).
The following sample generates CS0163.
// CS0163.cs public class MyClass { public static void Main() { int i = 0; switch (i) // CS0163 { // Compiler error CS0163 is reported on the following line. case 1: i++; // To resolve the error, uncomment one of the following example statements. // return; // break; // goto case 3; case 2: i++; return; case 3: i = 0; return; // Compiler error CS0163 is reported on the following line. default: Console.WriteLine("Default"); // To resolve the error, uncomment the following line: //break; } }
