char.toLower()

[sean]

int i;
char c;
while(true)
{
	i = Console.Read();
	if (i!=1)
	{
		c = (char) i;
		switch(c)
		{
		}
	}
}

Obviously inside the switch statement I'm going to have case statements like

case 'z': // do something; break;

but then there's the easily solved problem of case sensitivity. I have two options:

1) Is there a char equivalent of String.toLower()

2) It's been a while since I did this and my book does not explicitly clarify. In the following code, would my_function() execute regardless of the case of z/Z:

case 'z': case 'Z': my_function; break;

Thanks.

Sean,

1. There is a Char.ToUpper() method. There is also String.ToLower/ToUpper as well.

I would say

...

string s;
char c;

Console.WriteLine("Enter a character');
s = Console.ReadLine();
c =s[0] ;          //extract the 0 char from string

switch (c)
{
   case 'z':
   case 'Z':
   Console.WriteLine("Or do something");
   break;
   ...

}

Remember, about switch in C#

1.C# accepts strings enums as well as integers.

2. C# does not permit fall through. Break statements are required in C# unless two cases are combined with no statements between them (like above).

Also, what C# book are you using?? Since I have a C# project going on right now.

Mr. C.

Well actually I don't have a C# book. For syntax issues like this where it's likely to be very similar between the two languages, I refer to the User's Guide that came with my Borland Turbo C++ 3.0 for DOS compiler, and that is what I was talking about it. I don't even know where I learned C#. But thanks for the help!

edit: I'll be using chars, not strings, if anyones cares. I needed to program to execute the desired option after the user presses just one key.
