UInt16.Parse(String) Method in C# with Examples
Last Updated :

UInt16.Parse(String) Method is used to convert the string representation of a number to its 16-bit unsigned integer equivalent.
Syntax:
public static ushort 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 16-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:
csharp
// C# program to demonstrate
// UInt16.Parse(String) Method
using System;
class GFG {
// Main Method
public static void Main()
{
// passing different values
// to the method to check
checkParse("65535");
checkParse("15,784");
checkParse("-4589");
checkParse(" 785");
}
// Defining checkParse method
public static void checkParse(string input)
{
try {
// declaring UInt16 variable
ushort val;
// getting parsed value
val = UInt16.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:
'65535' parsed as 65535
Can't Parsed '15,784'
Can't Parsed '-4589'
' 785' parsed as 785
Example 2: For
ArgumentNullException
csharp
// C# program to demonstrate
// UInt16.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 UInt16 variable
ushort val;
// getting parsed value
val = UInt16.Parse(input);
Console.WriteLine("'{0}' parsed as {1}", input, val);
}
}
Output:
Exception Thrown: System.ArgumentNullException
