Returns a value that indicates whether this instance is equal to a specified object or Char value.

Overloads

Equals(Char)

Returns a value that indicates whether this instance is equal to the specified Char object.
Equals(Object)

Returns a value that indicates whether this instance is equal to a specified object.

Equals(Char)

Char.cs

Returns a value that indicates whether this instance is equal to the specified Char object.

public:
 virtual bool Equals(char obj);
public bool Equals(char obj);
override this.Equals : char -> bool
Public Function Equals (obj As Char) As Boolean

Parameters

obj
Char

An object to compare to this instance.

Returns

Boolean

true if the obj parameter equals the value of this instance; otherwise, false.

Implements

Equals(T)

Remarks

This method implements the System.IEquatable<T> interface, and performs slightly better than Char.Equals(Object) because it does not need to unbox the obj parameter.

public override bool Equals(object? obj);
override this.Equals : obj -> bool
Public Overrides Function Equals (obj As Object) As Boolean

Parameters

obj
Object

An object to compare with this instance or null.

Returns

Boolean

true if obj is an instance of Char and equals the value of this instance; otherwise, false.

Examples

The following code example demonstrates Equals.

using System;

public class EqualsSample {
    public static void Main() {
        char chA = 'A';
        char chB = 'B';

        Console.WriteLine(chA.Equals('A'));		// Output: "True"
        Console.WriteLine('b'.Equals(chB));		// Output: "False"
    }
}

let chA = 'A'
let chB = 'B'

printfn $"{chA.Equals 'A'}"    // Output: "True"
printfn $"{'b'.Equals chB}"    // Output: "False"

Module EqualsSample

    Sub Main()

        Dim chA As Char
        chA = "A"c
        Dim chB As Char
        chB = "B"c

        Console.WriteLine(chA.Equals("A"c))     ' Output: "True"
        Console.WriteLine("b"c.Equals(chB))     ' Output: "False"

    End Sub

End Module

Remarks

The comparison performed by this method is based on the encoded values of this instance and obj, not necessarily their lexicographical characteristics.
