How to compare two ValueTuple in C#?
To compare two instances of ValueTuple you can use CompareTo method which is provided by ValueTuple structure. ValueTuple.CompareTo(ValueTuple) Method is used to compare the current instance of ValueTuple with another ValueTuple instance. It always returns zero if they are equal to each other.
Syntax:
public int CompareTo (ValueTuple other);
Here, other is the object to compare with the current instance.
Returns: The method always returns 0 of type System.Int32.
Exception: This method will throw an ArgumentException if the other is not ValueTuple instance.
Example 1:
// C# program to illustrate the // concept of CompareTo method using System; class GFG { // Main method static public void Main() { // Creating value tuples with two elements var MyTple1 = ValueTuple.Create(56, 45); var MyTple2 = ValueTuple.Create(56, 3); var MyTple3 = ValueTuple.Create(56, 45); var MyTple4 = ValueTuple.Create(5345, 45); // Using CompareTo method int res1 = MyTple1.CompareTo(MyTple2); int res2 = MyTple1.CompareTo(MyTple3); int res3 = MyTple1.CompareTo(MyTple4); // Display result Console.WriteLine( "Result 1: " + res1); Console.WriteLine( "Result 2: " + res2); Console.WriteLine( "Result 3: " + res3); } } |
Output:
Result 1: 1 Result 2: 0 Result 3: -1
Example 2:
// C# program to illustrate the // use of CompareTo method using System; class GFG { // Main Method static public void Main() { // Creating value tuples with one element var MyVTple1 = ValueTuple.Create(2018); var MyVTple2 = ValueTuple.Create(2018); // Compare both value tuples // Using CompareTo method if (MyVTple1.CompareTo(MyVTple2) == 0) { Console.WriteLine( "Welcome to w3wiki" ); } else { Console.WriteLine( "Page Not Found" ); } } } |
Output:
