Char.Equals 方法

public:
 virtual bool Equals(char obj);

public bool Equals (char obj);

override this.Equals : char -> bool

Public Function Equals (obj As Char) As Boolean

參數

傳回

Boolean

當 true 參數等於這個執行個體的值時為 obj，否則為 false。true if the obj parameter equals the value of this instance; otherwise, false.

實作

備註

這個方法會實作為 System.IEquatable<T> 介面，而且執行方式稍微優於， Char.Equals(Object) 因為它不需要將參數取消裝箱 obj 。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.

• Equals(Object)

public:
 override bool Equals(System::Object ^ obj);

public override bool Equals (object obj);

public override bool Equals (object? obj);

override this.Equals : obj -> bool

Public Overrides Function Equals (obj As Object) As Boolean

參數

傳回

Boolean

如果 obj 是 Char 的執行個體，並且等於這個執行個體的值，則為 true，否則為 false。true if obj is an instance of Char and equals the value of this instance; otherwise, false.

範例

下列程式碼範例將示範 Equals 。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"
    }
}

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

備註

這個方法所執行的比較是以這個實例的編碼值為基礎 obj ，而不一定是其字典式特性。The comparison performed by this method is based on the encoded values of this instance and obj, not necessarily their lexicographical characteristics.
