UInt32.Parse(String) Method in C# with Examples
UInt32.Parse(String) Method is used to convert the string representation of a number to its 32-bit unsigned integer equivalent.
Syntax:
public static uint Parse (string str);
Here, str is a string containing a number to convert. The format of str will be [optional white space][optional sign]digits[optional white space]. The sign can be positive or negative. But negative sign can be used only with zero otherwise it will throw an OverflowException.
Return Value: It is a 32-bit unsigned integer equivalent to the number contained in str.
Exceptions:
- ArgumentNullException: If str is null.
- FormatException: If str is not in the correct format.
- OverflowException: If str represents a number less than MinValue or greater than MaxValue.
Below programs illustrate the use of above-discussed method:
Example 1:
// C# program to demonstrate// UInt32.Parse(String) Methodusing System; class GFG { // Main Method public static void Main() { // passing different values // to the method to check checkParse("4294967295"); checkParse("14244,784"); checkParse("-457589"); checkParse(" 784845"); } // Defining checkParse method public static void checkParse(string input) { try { // declaring UInt32 variable uint val; // getting parsed value val = UInt32.Parse(input); Console.WriteLine("'{0}' parsed as {1}", input, val); } catch (OverflowException) { Console.WriteLine("Can't Parsed '{0}'", input); } catch (FormatException) { Console.WriteLine("Can't Parsed '{0}'", input); } }} |
Output:
'4294967295' parsed as 4294967295 Can't Parsed '14244, 784' Can't Parsed '-457589' ' 784845' parsed as 784845
Example 2: For ArgumentNullException
// C# program to demonstrate// UInt32.Parse(String) Method// for ArgumentNullExceptionusing System; class GFG { // Main Method public static void Main() { try { // passing null value as a input checkParse(null); } catch (ArgumentNullException e) { Console.Write("Exception Thrown: "); Console.Write("{0}", e.GetType(), e.Message); } catch (FormatException e) { Console.Write("Exception Thrown: "); Console.Write("{0}", e.GetType(), e.Message); } } // Defining checkparse method public static void checkParse(string input) { // declaring UInt32 variable uint val; // getting parsed value val = UInt32.Parse(input); Console.WriteLine("'{0}' parsed as {1}", input, val); }} |
Output:
Exception Thrown: System.ArgumentNullException
