Parsing Values from String Data

The .NET data types provide the ability to generate a variable of their underlying type given a tex-

tual equivalent (e.g., parsing). This technique can be extremely helpful when you wish to convert a

bit of user input data (such as a selection from a GUI-based drop-down list box) into a numerical

value. Consider the following parsing logic within a method named ParseFromStrings():

static void ParseFromStrings()

{

Console.WriteLine("=> Data type parsing:");

bool b = bool.Parse("True");

Console.WriteLine("Value of b: {0}", b);

double d = double.Parse("99.884");

Console.WriteLine("Value of d: {0}", d);

int i = int.Parse("8");

Console.WriteLine("Value of i: {0}", i);

char c = Char.Parse("w");

Console.WriteLine("Value of c: {0}", c);

Console.WriteLine();

}
