Sobrecargas

Equals(ReadOnlySpan<Char>)	Devuelve un valor que indica si los caracteres de esta instancia son iguales a los caracteres de un intervalo de caracteres especificado de solo lectura.
Equals(StringBuilder)	Devuelve un valor que indica si esta instancia equivale a un objeto especificado.

Equals(ReadOnlySpan<Char>)

Source:: StringBuilder.cs

Source:: StringBuilder.cs

Source:: StringBuilder.cs

Devuelve un valor que indica si los caracteres de esta instancia son iguales a los caracteres de un intervalo de caracteres especificado de solo lectura.

public:
 bool Equals(ReadOnlySpan<char> span);

public bool Equals (ReadOnlySpan<char> span);

override this.Equals : ReadOnlySpan<char> -> bool

Public Function Equals (span As ReadOnlySpan(Of Char)) As Boolean

Parámetros

span: ReadOnlySpan<Char>

El intervalo de caracteres que se va a comparar con la instancia actual.

Devoluciones

Boolean

true si los caracteres de esta instancia y span son iguales; en caso contrario, false.

Comentarios

El Equals método realiza una comparación ordinal para determinar si los caracteres de la instancia actual y span son iguales.

Se aplica a

Equals(StringBuilder)

Source:: StringBuilder.cs

Source:: StringBuilder.cs

Source:: StringBuilder.cs

Devuelve un valor que indica si esta instancia equivale a un objeto especificado.

public:
 bool Equals(System::Text::StringBuilder ^ sb);

public bool Equals (System.Text.StringBuilder sb);

public bool Equals (System.Text.StringBuilder? sb);

override this.Equals : System.Text.StringBuilder -> bool

Public Function Equals (sb As StringBuilder) As Boolean

Parámetros

sb: StringBuilder

Objeto que se va a comparar con esta instancia o null.

Devoluciones

Boolean

true si esta instancia y sb tienen los mismos valores de cadena, Capacity y MaxCapacity; en caso contrario, false.

Ejemplos

El código siguiente usa el Equals método para comprobar si dos StringBuilder objetos son iguales. Se llama al método repetidamente después de realizar pequeños cambios en cada objeto y los resultados se muestran en la consola.

using namespace System;
using namespace System::Text;
int main()
{
   StringBuilder^ sb1 = gcnew StringBuilder( "abc" );
   StringBuilder^ sb2 = gcnew StringBuilder( "abc",16 );
   Console::WriteLine();
   Console::WriteLine( "a1) sb1->Length = {0}, sb1->Capacity = {1}", sb1->Length, sb1->Capacity );
   Console::WriteLine( "a2) sb2->Length = {0}, sb2->Capacity = {1}", sb2->Length, sb2->Capacity );
   Console::WriteLine( "a3) sb1 = \"{0}\", sb2 = \"{1}\"", sb1, sb2 );
   Console::WriteLine( "a4) sb1 equals sb2: {0}", sb1->Equals( sb2 ) );
   Console::WriteLine();
   Console::WriteLine( "Ensure sb1 has a capacity of at least 50 characters." );
   sb1->EnsureCapacity( 50 );
   Console::WriteLine();
   Console::WriteLine( "b1) sb1->Length = {0}, sb1->Capacity = {1}", sb1->Length, sb1->Capacity );
   Console::WriteLine( "b2) sb2->Length = {0}, sb2->Capacity = {1}", sb2->Length, sb2->Capacity );
   Console::WriteLine( "b3) sb1 = \"{0}\", sb2 = \"{1}\"", sb1, sb2 );
   Console::WriteLine( "b4) sb1 equals sb2: {0}", sb1->Equals( sb2 ) );
   Console::WriteLine();
   Console::WriteLine( "Set the length of sb1 to zero." );
   Console::WriteLine( "Set the capacity of sb2 to 51 characters." );
   sb1->Length = 0;
   sb2->Capacity = 51;
   Console::WriteLine();
   Console::WriteLine( "c1) sb1->Length = {0}, sb1->Capacity = {1}", sb1->Length, sb1->Capacity );
   Console::WriteLine( "c2) sb2->Length = {0}, sb2->Capacity = {1}", sb2->Length, sb2->Capacity );
   Console::WriteLine( "c3) sb1 = \"{0}\", sb2 = \"{1}\"", sb1, sb2 );
   Console::WriteLine( "c4) sb1 equals sb2: {0}", sb1->Equals( sb2 ) );
}

Comentarios

.NET Framework y .NET Core 2.2 y versiones anteriores: La instancia actual y sb son iguales si tienen valores iguales de cadena, Capacityy MaxCapacity . El Equals método usa la comparación ordinal para determinar si las cadenas son iguales.

.NET Core 3.0 y versiones posteriores: La instancia actual y sb son iguales si las cadenas asignadas a ambos StringBuilder objetos son iguales. Para determinar la igualdad, el Equals método usa la comparación ordinal. Los Capacity valores de propiedad y MaxCapacity no se usan en la comparación.
