# String.Inequality(String, String)String.Inequality(String, String)String.Inequality(String, String)String.Inequality(String, String) Operator

## Definition

Bestimmt, ob zwei angegebene Zeichenfolgen verschiedene Werte haben.Determines whether two specified strings have different values.

public:
static bool operator !=(System::String ^ a, System::String ^ b);
public static bool operator != (string a, string b);
static member op_Inequality : string * string -> bool
Public Shared Operator != (a As String, b As String) As Boolean

#### Parameter

a
String String String String

Die erste Zeichenfolge für den Vergleich oder null.The first string to compare, or null.

b
String String String String

Die zweite Zeichenfolge für den Vergleich oder null.The second string to compare, or null.

#### Gibt zurück

true, wenn der Wert von a vom Wert von b verschieden ist; andernfalls false.true if the value of a is different from the value of b; otherwise, false.

## Beispiele

Im folgenden Beispiel wird der Ungleichheits Operator veranschaulicht.The following example demonstrates the inequality operator.

// Example for the String Inequality operator.
using namespace System;
void CompareAndDisplay( String^ Comparand )
{
String^ Lower = "abcd";
Console::WriteLine( "\"{0}\" != \"{1}\" ?  {2}", Lower, Comparand, Lower != Comparand );
}

int main()
{
Console::WriteLine( "This example of the String Inequality operator\n"
"generates the following output.\n" );
CompareAndDisplay( "ijkl" );
CompareAndDisplay( "ABCD" );
CompareAndDisplay( "abcd" );
}

/*
This example of the String Inequality operator
generates the following output.

"abcd" != "ijkl" ?  True
"abcd" != "ABCD" ?  True
"abcd" != "abcd" ?  False
*/
// Example for the String Inequality operator.
using System;

class InequalityOp
{
public static void Main()
{
Console.WriteLine(
"This example of the String Inequality operator\n" +
"generates the following output.\n" );

CompareAndDisplay( "ijkl" );
CompareAndDisplay( "ABCD" );
CompareAndDisplay( "abcd" );
}

static void CompareAndDisplay( String Comparand )
{
String  Lower = "abcd";

Console.WriteLine(
"\"{0}\" != \"{1}\" ?  {2}",
Lower, Comparand, Lower != Comparand );
}
}

/*
This example of the String Inequality operator
generates the following output.

"abcd" != "ijkl" ?  True
"abcd" != "ABCD" ?  True
"abcd" != "abcd" ?  False
*/

## Hinweise

Die Inequality -Methode definiert den Vorgang des Ungleichheits Operators für String die-Klasse.The Inequality method defines the operation of the inequality operator for the String class. Sie ermöglicht Code wie im Abschnitt "Beispiele".It enables code such as that shown in the Examples section.

Der Inequality -Operator ruft wiederum die statische Equals(String, String) -Methode auf, die einen Ordinalvergleich (Groß-/Kleinschreibung und Kultur unabhängige) ausführt.The Inequality operator in turn calls the static Equals(String, String) method, which performs an ordinal (case-sensitive and culture-insensitive) comparison.

Hinweis

Der Visual Basic-Compiler löst den Ungleichheits Operator nicht als Aufrufe der Inequality -Methode auf.The Visual Basic compiler does not resolve the inequality operator as a call to the Inequality method. Stattdessen umschließt der Ungleichheits Operator einen Rückruf für Operators.CompareString die-Methode.Instead, the inequality operator wraps a call to the Operators.CompareString method.
