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:
using System;
class GFG {
public static void Main()
{
checkParse( "65535" );
checkParse( "15,784" );
checkParse( "-4589" );
checkParse( " 785" );
}
public static void checkParse( string input)
{
try {
ushort val;
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
using System;
class GFG {
public static void Main()
{
try {
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);
}
}
public static void checkParse( string input)
{
ushort val;
val = UInt16.Parse(input);
Console.WriteLine( "'{0}' parsed as {1}" , input, val);
}
}

Output:
Exception Thrown: System.ArgumentNullException
