String.Inequality Operator (String, String)
.NET Framework (current version)
Determines whether two specified strings have different values.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- a
-
Type:
System.String
The first string to compare, or null.
- b
-
Type:
System.String
The second string to compare, or null.
Return Value
Type: System.Booleantrue if the value of a is different from the value of b; otherwise, false.
The Inequality method defines the operation of the inequality operator for the String class. It enables code such as that shown in the Examples section.
The Inequality operator in turn calls the static Equals(String, String) method, which performs an ordinal (case-sensitive and culture-insensitive) comparison.

The Visual Basic compiler does not resolve the inequality operator as a call to the Inequality method. Instead, the inequality operator wraps a call to the Operators.CompareString method. |
