UInt16.CompareTo() Method in C# with Examples

Last Updated : 11 Jul, 2025
UInt16.CompareTo Method is used to compare the current instance to a specified object or another UInt16 instance. It returns an integer which shows whether the value of the current instance is less than, equal to, or greater than the value of the specified object or the other UInt16 instance. There are 2 methods in the overload list of this method as follows:
  • CompareTo(UInt16) Method
  • CompareTo(Object) Method

UInt16.CompareTo(UInt16) Method

This method is used to compare the current instance to a specified 16-bit unsigned integer and returns an integer which shows whether the value of the current instance is less than, equal to, or greater than the value of the specified 16-bit unsigned integer. Syntax:
public int CompareTo (ushort value);
Here, it takes an unsigned integer to compare. Return Value: It returns a 32-bit signed number indicating the relative values of current instance and value parameter as follows:
  • Less than Zero: if Current Instance < value
  • Zero: if Current Instance = value
  • Greater than Zero: if Current Instance > value
Below programs illustrate the use of UInt16.CompareTo(UInt16) Method Example 1:
Output:
7 is less than 98
Example 2:
Output:
54 is less than 77
70 is less than 95
10 is less than 24
45 is equal to 45

UInt16.CompareTo(Object) Method

This method is used to compare the current instance to a specified object and returns an integer which indicates whether the value of the current instance is less than, equal to, or greater than the value of the object. Syntax:
public int CompareTo (object value);
Here, it takes the object to compare with this instance, or null. Return Value: It returns a 32-bit signed number indicating the relative values of current instance and value parameter as follows:
  • Less than Zero: if Current Instance < value
  • Zero: if Current Instance = value
  • Greater than Zero: if Current Instance > value
Exception: It throws ArgumentException if value is not UInt16. Below programs illustrate the use of UInt16.CompareTo(Object) Method Example 1:
Output:
10 is less than 56
Example 2: For ArgumentException
Output:
value2 must be null or an instance of UInt16
Exception Thrown: System.ArgumentException
