Question

I have a program that reads in serial information from a device and that works fine but i want to make a statement something like;
if (first character = R)
do something
if (first character = T)
do something else

I hope this makes sense. Basically all i need to do is have a way to detect the first character from a variable, then remove that character from the variable.

Thanks

Assuming we are talking about a string:

string input = GetInput();
string remainingPart = input.Substring(1); // get string without first character
switch (input[0])
{
    case 'R':
        {
            DoSomething(remainingPart);
            break;
        }
    case 'T':
        {
            DoSomethingElse(remainingPart);
            break;
        }
    // more case clauses follow here
    default:
        {
            break;
        }
}
