What it does:
Double.TryParse tries to convert a string into a double.
It returns true if the conversion is successful; otherwise, it returns false.
It does not throw an exception if the input is invalid — very safe to use!
Syntax:
bool double.TryParse(string strValue, out double result);
strValue → The input string you want to convert.
result → The output variable where the parsed double will be stored if successful.
Example Code:-
using System;
namespace ConsoleAppVerifyInput
{
internal class Program
{
static void Main(string[] args)
{
//double.TryParse()
bool a = true;
do
{
Console.Clear();
Console.WriteLine("Enter Any Number :-");
string strValue = Console.ReadLine();
if(double.TryParse(strValue,out double NumValue))
{
Console.WriteLine($"User Input Number is {NumValue}");
a = false;
}
else
{
Console.WriteLine("Invalid Number");
}
Console.ReadKey();
} while(a);
}
}
}
How it Works:
If the user types 12.3, TryParse stores 12.3 in the number, and isValid is true.
If the user types abc, TryParse fails, number is 0, and isValid is false.
Why use TryParse instead of Parse?
Parse (like double. Parse) throws an exception if the input is invalid.
TryParse avoids exceptions — it's safer and better for real-world apps!
