NumericInput
NumericInput is a library that simplifies the task of receiving numeric input and input validation in C#. When using Console.ReadLine()
to receive numeric input, you need to convert the string to a number. This library streamlines that process.
Installation
To use the library, include using NumericInput;
in your code.
Features
ReadInteger()
: Prompts the user for an integer input and repeatedly requests input until a valid integer is entered.ReadDouble()
: Prompts the user for a double input and repeatedly requests input until a valid double is entered.IsVaildNum(string value)
: Checks if the given string is a valid number.
Usage Examples
Traditional Input Method
class Program
{
static void Main(string[] args)
{
// Read an integer
Console.Write("Enter an integer: ");
string intInput = Console.ReadLine();
int intValue;
while (!int.TryParse(intInput, out intValue))
{
Console.WriteLine("Invalid input. Please enter an integer.");
Console.Write("Enter an integer: ");
intInput = Console.ReadLine();
}
Console.WriteLine($"You entered: {intValue}");
// Read a double
Console.Write("Enter a decimal number: ");
string doubleInput = Console.ReadLine();
double doubleValue;
while (!double.TryParse(doubleInput, out doubleValue))
{
Console.WriteLine("Invalid input. Please enter a number.");
Console.Write("Enter a decimal number: ");
doubleInput = Console.ReadLine();
}
Console.WriteLine($"You entered: {doubleValue}");
// Use IsValidNum
Console.Write("Enter a number or text: ");
string input = Console.ReadLine();
double value;
if (double.TryParse(input, out value))
{
Console.WriteLine($"You entered a valid number: {value}");
}
else
{
Console.WriteLine($"'{input}' is not a valid number.");
}
}
}
Using NumericInput Library
using NumericInput;
class Program
{
static void Main(string[] args)
{
// Read an integer
Console.Write("Enter an integer: ");
int intValue = Numeric.ReadInteger();
Console.WriteLine($"You entered: {intValue}");
// Read a double
Console.Write("Enter a decimal number: ");
double doubleValue = Numeric.ReadDouble();
Console.WriteLine($"You entered: {doubleValue}");
// Use IsValidNum
Console.Write("Enter a number or text: ");
string input = Numeric.ReadInput();
if (Numeric.IsValidNum(input))
{
double value = double.Parse(input);
Console.WriteLine($"You entered a valid number: {value}");
}
else
{
Console.WriteLine($"'{input}' is not a valid number.");
}
}
}
