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

- obj
- Char
An object to compare to this instance.
Returns
true
if the obj
parameter equals the value of this instance; otherwise, false
.

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.

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

Examples
The following code example demonstrates Equals.
using namespace System;
int main()
{
char chA = 'A';
char chB = 'B';
Console::WriteLine( chA.Equals( 'A' ) ); // Output: "True"
Console::WriteLine( 'b'.Equals( chB ) ); // Output: "False"
}
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.
