Binary String to Integer

Question

I have a binary string, entered by the user, which I need to convert to an integer.

At first I naivly used this simple line:

Convert.ToInt32(\"11011\         


        

Answer 1

Thanks for the great and incredibly fast answer!

Unfortunately, my requirements changed. Now the user can pretty much enter any format. Binary, Decimal, Hex. So I decided try - catch just provides the simplest and cleanest solution.

So just for good measure I am posting the code I am using now. I think it is pretty clear and even somewhat elegant, or so I think^^.

switch (format)
{
    case VariableFormat.Binary:
        try
        {
            result = Convert.ToInt64(value, 2)
        }
        catch
        {
            // error handling
        }
        break;
    case VariableFormat.Decimal:
        try
        {
            result = Convert.ToInt64(value, 10)
        }
        catch
        {
            // error handling
        }
        break;
    case VariableFormat.Hexadecimal:
        try
        {
            result = Convert.ToInt64(value, 16)
        }
        catch
        {
            // error handling
        }
        break;
}

So thanks for encouraging me to use try - catch, I think it really improved the readibility of my code.

Thanks
