Question

I have two questions with this code:

public int InsertOrUpdateRecord(char _code, string _databaseFileName)
{

   switch(_code)
   {
      case 'N':
           // Some code here

       case 'U':
           // Some code here
   }
       return 0;
}

1. It is not accepting char single quote and double quote value.
2. If I pass _code as string, it gives red underline in case with this error:

Control cannot fall through one case label to another.

Answer 1

The reason for the compilation error is that the case is missing the break

switch (_code)
{
    case 'N':
    // Some code here
        break; // break that closes the case

    case 'U':
    // Some code here
        break; // break that closes the case
}
