Compiler Error CS0161

'method': not all code paths return a value

A method that returns a value must have a return statement in all code paths. For more information, see Methods.

Example

The following sample generates CS0161:

// CS0161.cs
public class Test
{
    public static int Main() // CS0161
    {
        int i = 5;
        if (i < 10)
        {
            return i;
        }
        else
        {
            // Uncomment the following line to resolve.
            // return 1;  
        }
    }
}
