This print for content only-size & color not accurate 7" X 9-1/4" / casebound / malloy

// Get name and age.

Console.Write("Please enter your name: ");

string userName = Console.ReadLine();

Console.Write("Please enter your age: ");

string userAge = Console.ReadLine();

// Change echo color, just for fun.

ConsoleColor prevColor = Console.ForegroundColor;

Console.ForegroundColor = ConsoleColor.Yellow;

// Echo to the console.

Console.WriteLine("Hello {0}!  You are {1} years old.",

userName, userAge);

// Restore previous color.

Console.ForegroundColor = prevColor;

}

Not surprisingly, when you run this application, the input data is printed to the console (using

a custom color to boot!).

Formatting Console Output

During these first few chapters, you may have noticed numerous occurrences of the tokens {0}, {1},

and the like embedded within various string literals. The .NET platform introduces a style of string

formatting slightly akin to the printf() statement of C. Simply put, when you are defining a string

literal that contains segments of data whose value is not known until runtime, you are able to spec-

ify a placeholder within the literal using this curly-bracket syntax. At runtime, the value(s) passed

into Console.WriteLine() are substituted for each placeholder.

The first parameter to WriteLine() represents a string literal that contains optional place-

holders designated by {0}, {1}, {2}, and so forth. Be very aware that the first ordinal number of a

curly-bracket placeholder always begins with 0. The remaining parameters to WriteLine() are sim-

ply the values to be inserted into the respective placeholders.
