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) Method using 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);
}
}
} |
'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 ArgumentNullException using 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);
}
